OAR@ICRISATManaging and Discovering Agronomically Beneficial Traits in Chickpea Germplasm CollectionsH DUpadhyayaauthorS LDwivediauthorSSharmaauthorAccess to crop biodiversity is foremost to address new challenges to agricultural production. The chickpea genetic resources maintained at ICRISAT genebank have been characterized for morpho-agronomic traits. The passport and characterization data were used to form representative subsets: core/mini core collections and genotyping data of composite collection was used to form reference set. The chickpea core and mini core collections, respectively, consist of 1956 and 211 accessions, while reference set 300 accessions. These subsets are ideal genetic resource to dissect population structure and diversity, identify new sources of variations, mine allelic variation, and conduct association genetics to identify QTLs associated with agronomic traits which upon validation may be used in applied breeding. Using mini core collection, a number of accessions with early maturity, high yield and large seed size, seed nutritional traits, and stress tolerance were identified, including some with high yield and multiple stress tolerance. A systematic program is underway to introgress wild Cicer gene(s) to enhance levels of resistance and to broaden the genetic base of cultigen genepool.ChickpeaGenetics and GenomicsGermplasmLegume Crops2017SpringerBook Section
