Trait variations for seed physical characteristics in chickpea (Cicer arietinum L.) from the Western Himalayas

Chickpea (Cicer arietinum L.) is one of the most important grain legumes after common bean. In the present study, a total of 35 chickpea genotypes including desi and Kabuli types of cultivated chickpea (C. arietinum) were evaluated for seed physical characteristics that are very important for seed storage, processing and determining seed quality traits. Therefore, it has become imperative to study the seed physical characteristics of chickpea during the present study. The analysis of data revealed that substantial variation is present among the genotypes under study with respect to seed physical characteristics such as seed size, seed volume, seed density, hydration capacity, hydration index, swelling capacity and swelling index. These traits are considered important to determine the seed rate at the time of sowing of the crop, cooking quality, storage and processing and thereby have a direct bearing on the economics of chickpea consumption. Our results indicated that the desi, Kabuli and pea-shaped genotypes differ significantly in seed physical characteristics with overall superior trait performance of the Kabuli type compared to other seed types, making them superior with respect to consumer/market demands.
