Product Description/Background

Worldwide, chickpea is the fourth largest grain legume crop, predominantly grown in Asia. CGIAR’s and NARS genebanks maintain large collections of chickpea germplasm. However, globally there has been very limited use of genebank materials for the genetic enhancement of chickpea due to the very large size of the collections and limited resources by researchers to evaluate accessions. To address this constraint, a composite collection of 3000 accessions was developed and profiled using 50 SSRs and high throughput assays.  A total of 1741 alleles were detected in the composite collection, of which 968 were rare and 773 common alleles.  A complete data set of 49 SSRs on 2915 accessions was used to dissect the structure and diversity in the composite collection and form this reference set of 300 accessions which captures 1315 (78%) of the 1683 composite collection alleles.  The reference set represents a critical resource for plant scientists to study new adaptive traits, discover new favorable alleles and also new parental lines for pre-breeding crosses.

Associated SSR marker kit:

The reference kit results from the formation of the Chickpea Reference Set and is composed of 35 SSRs with a sequence list and protocol, germplasm checks, and allele sizes of markers for those checks.  Access the detailed list at   http://www.icrisat.org/Marker-Kits.html
