Morphometric variation in wild chickpea seeds.

The size, shape, and color of seeds were among the central traits selected during domestication of grain legumes and cereals.  Here we examine variation across 20 populations of the immediate wild relatives of chickpea, Cicer reticulatum and Cicer echinospermum, from southeastern TurkeyWe find substantial heritable variation in size, shape, and color across populations.  Seeds from all wild populations were smaller than most common modern varieties of chickpea, but approach the size range of smaller seeded desi varieties.  Morphometric analysis shows three-dimensional variation in shape, which are concordant with patterns of genetic variation.
