Mining the chickpea composite collection for allelic variation uri icon

abstract

  • Chickpea, Cicer arietinum L., is believed to have originated in south-east Turkey. However, atpresent, the major chickpea-growing countries are India, Pakistan, Iran, Turkey, Australia,Ethiopia, and Mexico. Chickpea is a leguminous food crop, self-pollinating, and diploid. Itsgene pool consists of 43 species: one annual cultivated (i.e. chickpea), eight annual wild, and34 perennial wild species. Two types of chickpea are known: desi types with colouredflowers, and angular-shaped and dark-coloured seeds, primarily grown in South Asia andAfrica; and kabuli types with white flowers, owl?s head-shaped and beige-coloured seeds,and grown mostly in Mediterranean countries. To study the allelic richness and diversityassociated with beneficial traits, a composite set of 3000 chickpea germplasm accessions wasconstituted. This set included the chickpea core collection, old and new cultivars and traitspecificgermplasm accessions from ICRISAT and accessions representing the ICARDAcollection
