Laboratory methods

Describes the various recommended options, to test the viability and quality of chickpea seeds. The percentage of germination of the stored seeds of the accessions determines when regeneration of the accessions should take place and if the accession can be distributed to the users.

Type of test

When sufficient seed is available:

  • Use a standard viability test (between paper, BP), following the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009).

When the seed sample is small:

Number of seeds and replicates

  • Use 50-100 seeds in 2-4 replications (following the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009); FAO/IPGRI standards, 1994; Normative ISTA and AOSA; ‘Methodics examinations seed and plant, of State variety trials’. Bratislava. 1999. Slovak Republic).

Or

Pre-treatment

Follow the recommendations of the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009):

  • Apply a dry seed treatment with fungicide at 3 g/kg seed.
  • Scarify the seed coat for hard seeds, especially wild Cicer species.

To avoid seed damage resulting from rapid moistening by liquid water in germination substrate, and to improve germination:

  • Re-humidify (90% RH) seeds stored in dry and cool environments (-18oC).
  • Pre-chill the re-humidified seeds (10oC for 48 hours) followed by germination according to ISTA standards.

Media

Following the recommendations of the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009):

  • Standard paper towel is best and cost effective.
  • Alternatively, germination boxes with artificial soil (turf, vermiculate, etc.) using tap water may be used.

Temperature

According to the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009) and the ISTA Standards:

  • 20-25ºC.

Light

According to the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009):

  • Not required.

Duration of test

According to the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009) and the ISTA Standards:

  • 5-10 days after incubation.

Interpretation of results

According to the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009) and the ISTA Standards (2003, 2005), Association of Official Seed Analysts (AOSA) Standards (2005):

  • Scarify hard and ungerminated seeds and evaluate 14 days after incubation.
  • If the mean viability percentage of the accession is below 85% (75% for wild species), repeat the test.
  • Calculate the mean viability percentage from the results of the two tests and use this as the overall test result.
  • If the results are far below the germination standard, the accession should be sent to regeneration.

Monitoring intervals

According to the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009):

For the active collection (4ºC and 20-30% RH)

  • Germination less than 85% - 5 years.
  • Germination 85-95% - 8 years.
  • Germination 95% or more - 10 years.

For the base collection (-20ºC)

  • Germination less than 85% - 10 years.
  • Germination 85-95% - 15 years.
  • Germination 95% and more - 20 years.

Other option

According to Ellis' and Robert's predictive model with log parameters for initial viability, seed storage temperature and moisture content were used to monitor viability. This was more efficient than routine calendar interval monitoring of viability of collections such as every 5–10 years:

  • As per predicted longevity: 20-30 years after initial regeneration and viability testing.

Routine monitoring

Describes the recommended monitoring methods to assure minimum viability and quantity of seeds in storage.

  • Routine inventory management of active collection and base collection using a Genebank Information Management System (GIMS).
  • Aim viability of germplasm seed stock at 85% or more, based upon seed age and predicted viability from storage trial (to keep viable seed of all accessions available for distribution, and that seed stock is sufficient for both regeneration and distribution requirements).
  • Monitor when seed quantity in active storage falls below 100 g.
  • Monitoring – five years in the active collection, ten years in the base collection (recommended in the FAO/IPGRI standards, 1994).
  • Use the computerized stock control system to monitor the quality and quantity of seed accessions in the cold store.

Monitoring frequency

Recommends the minimum quantity and minimum viability of seeds below which they need to be regenerated.

Critical quantity

To be detected by data on stocks in the Genebank Information Management System (GIMS) (according to FAO/IPGRI standards, 1994; ISTA Standards).

  • For the active collection: critical quantity less than 100 g.
  • For the base collection: When the number of seeds falls below the number required for at least three cycles of regeneration.
  • For wild Cicer: 300 seeds.

Critical germination level

To be detected by data on stocks in the Genebank Information Management System (GIMS) (according to FAO/IPGRI standards, 1994; ISTA Standards).

  • For the active collection: critical germination level less than 75%.
  • For the base collection: when viability falls below 85% of the initial value.
  • For wild Cicer: critical germination level: less than 75%.
 

Recording information during storage monitoring

The following information should be recorded for each step:

  • Seed moisture content (% wet basis).
  • Date when accession was sent for regeneration (date, person) [date accessions were sent for regeneration in the field (dd/mm/yyyy)].
  • Date of receiving newly regenerated seeds of the accession (date, seed germination, others). According to accepted protocols for seed handling in genebanks.
  • Number of regenerations (frequent regeneration can affect germplasm identity).
  • Date of next test (one year: if germination % is close to critical value; five years: when it is above 85%).

Base collection

long_term_storage_facility
Long-term storage facility (photo: ICRISAT)

A base collection is a long-term storage. The initial population is used as a bench mark for monitoring changes in genetic diversity over time and after several cycles of regeneration due to genetic drift. It should ensure that an accession’s seed viability remains at acceptable levels for at least 50 years, or at least one cycle of the regeneration of the accession.

When it should be used

  • When aiming to store seeds for 50-100 years (Upadhyaya and Laxmipathi, 2009); FAO/IPGRI Standards, 1994).
  • Priority should be given to landraces, released varieties, wild relatives of crops and special genetic stocks.
    • Landraces contain the greatest crop diversity with accessions adapted to a myriad of agro–ecological environments through long-term evolution in these localities.
    • Breeding lines do not qualify as they are of short-term interest to breeders and continually displaced with each new breeding cycle.
  • When needing to rejuvenate the medium-term collections, often after three multiplication cycles (so as to maintain genetic integrity of the original population).

Sample specifications

Minimum sample size for storage

A representative sample should be used to avoid genetic drift (Upadhyaya and Laxmipathi, 2009).

  • For cultivated species: 1500-2000 seeds.
  • For wild Cicer species: 300 seeds.

Minimum viability for storage

  • Cultivated species: seeds with 90% or more viability.
  • Wild Cicer species: seeds with 80% or more viability.

Moisture content

Important to avoid any deterioration pf the stored seed samples.

Container specifications

Seed packaging method

Follow the procedures of the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009).

  • Prepare and label the aluminum foil packets with computer generated self-adhesive labels with the accession number, identity and season of harvest.
  • Take out few samples at the time from the drying room to minimize re-absorption of moisture by the seed lot.
  • Weigh the amount of seed prepared for storage and fill the container with seeds having at least 2.5 cm headspace for labelling.
  • Place a non-adhesive label highlighting accession number, identity and season of harvest inside the packet.
  • Seal the container using a standard vacuum sealer.
  • Check for any deficiencies in packets and sealing.
  • Print the date of sealing on the packet and move the samples to the long-term storage.

Specifications of packaging material

Follow the procedures of the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009) and FAO/IPGRI Standards, 1994.

  • Use three layered standard aluminum foil packets consisting of the following layers:

    • Alufoil 33 g/m2 [a middle layer of 33 g (12 mm) aluminum foil and 4 g lacquer].
    • Polyethylene 63 g/m2 (an inner layer of 63 g polyethylene).
  • Use packets size of 190 x 160 mm for holding approximately 200 g of seed.

Storage specifications

Assigning location codes

Follow the procedures of the ICRISAT Genebank Manual (Upadhyaya and Laxmipathi, 2009).

  • Use the exact location where the sample will be stored in the base collection (e.g. coded as 05-A-VI-06-132 indicating the room, rack, bay, shelf and tray numbers).
  • Use computerized codes (for quick and easy retrieval of material).
  • Use a barcode system (Genebank Information Management System, GIMS).

Storage conditions

Storage management

Storage space arrangement

It is very important to provide easy access to the accessions.

If the genebank's main function is distibution of germplasm, then adopting a two-step storage system for maintaining active collections and base collections at controlled environments is recommended, otherwise a long-term storage condition should be adopted (Upadhyaya and Laxmipathi, 2009).

System for tracking material/inventory system

Samples must be quickly accessed.

  • Develop a facility/database for tracking various operations including the inventory management for active, base and duplicate collections on Genebank Information Management System (GIMS):
    • Passport details.
    • Seed storage details.
    • Sample location/position in cold rooms.
    • Distribution of accessions (in the country and abroad).
  • Storage should be arranged by crop and by accession number within the crop. Accession pouches should be labelled internally and externally with durable numbered and barcoded waterproof labels.
  • Separate blocks of accession numbers with large margins should be assigned for each crop. This facilitates the correct retrieval of germplasm for distribution and for regeneration.

  • Phytosanitary inspections may require an additional time, even up to three to four weeks.

Customer assurance

Based on GIMS, Germplasm catalogues, SINGER database; PGRFA policy for free and open access to germplasm and documentation.

  • Improved and updated characterization and passport databases.
  • Knowledge on the collection.
  • Well classified and documented information on collections.
  • The material is sent based upon the type of request (targeted/non-targeted).

Feedback from users

Send a Germplasm Utilization Feedback form with every supply, with the following issues:

  • Comments on the appropriateness of the material supplied.
  • Voluntary feedback of evaluation data.
  • Performance of the accessions under different environmental conditions and the special traits observed.

Quantity of material recommended to be distributed

Unless special urgent circumstances are presented (Upadhyaya and Laxmipathi, 2009):

  • Cultivated chickpea – 100 seeds.
  • Wild Cicer – 10 seeds.

Procedures for distribution

Check availability

  • Check the existence of seeds using the inventory management system and physical verification (Upadhyaya and Laxmipathi, 2009).
  • Check the availability in stock using the inventory management system and physical verification (GIMS).
  • Check the passport data, especially the status of designation using an electronic version of the databases (GIMS).

Preparing samples for distribution

  • Registering the request (GIMS).
    • Do an automatic registration using the distribution module.
    • Requests should be registered with a number and filed electronically for future feedback.
  • Preparing a list of accessions available with an inventory management system and manual (GIMS).
    • Checking requirements for material transfer agreements using manual and electronic databases (GIMS).
  • Generating labels.
    • Generate labels for the selected accessions using the module Numeric/bar code ID fixed with adhesive and stapled on all seed packets for each accession (GIMS).
  • Labelling the accession containers (Upadhyaya and Laxmipathi, 2009).
    • Manual pasting on metal folding paper envelops.
    • Label should be affixed to each seed packet and packets should be enclosed in a sealed plastic bag and placed in box / padded envelope for shipment.
  • Check the inventory file and note the location of the container (Upadhyaya and Laxmipathi, 2009).
  • Remove containers from the genebank and perform the acclimatization procedures required (Upadhyaya and Laxmipathi, 2009).
    • For smaller numbers of samples, containers should not be removed from the genebank. Samples should be directly drawn and kept under ambient conditions for supply.
    • For large numbers of samples, take the containers from the genebank and move them out to a dehumidified room the previous evening to allow them to warm up to room temperature before opening.
  • Assuring accuracy in identification (GIMS).
    • Cross-check identification with passport and characterization databases.
    • Visual and barcode verification with label on storage pouch for each accession.
  • Extracting samples from the original containers.
    • In a two-way system of active and base collections, the source for distribution should only be the active collection. The base collection and the reference samples should not be used for seed supply (Upadhyaya and Laxmipathi, 2009).

Preparing the information list to accompany the plant material

According to the Genebank Manual of ICRISAT (Upadhyaya and Laxmipathi, 2009).

  • Passport data (Germplasm Assembly Module of GIMS).
  • Accession identification and alternate identity (Germplasm Assembly Module of GIMS).
  • Source country (Germplasm Assembly Module of GIMS).
  • Location and biological status (Germplasm Assembly Module of GIMS).
  • Limited characterization data used to verify accessions (Germplasm Characterization Module of GIMS).
  • Standard Material Transfer Agreement (SMTA).
  • Cover letter (detailed cover letter on the consignment and related documents with necessary suggestions on using the material).

Dispatching the plant material

According to the Genebank Manual of ICRISAT (Upadhyaya and Laxmipathi, 2009)

  • Pack the seed envelopes, covering letter, phytosanitary certificate, import permit, GMO free certificate and seed list in a jiffy bag or suitable size cardboard box.
  • Label it with the complete address of the consignee.
  • Use filling material to avoid damage to seeds during transit.
  • Include a reply form.
  • Attach acknowledgment letter and SMTA form for reply with every consignment.
  • If germplasm is a wild species, additional information for germinating seeds is enclosed.
  • Send the plant materials with a standard post, but may use courier, if urgent.
  • Record shipping details, the request number, date of sending the material and destination for retracing, if material is lost in transit.
  • Update the inventory of genebank.
    • Necessary for future distribution as well as for regeneration purposes.
    • Dynamic updating of seed stock weight in collection is important, while packaging seed for request.
