Abstract
Root traits, such as rooting depth and root biomass, have been identified as the most promising plant traits in chickpea for terminal drought tolerance. With this objective six genotypes of chickpea, viz, H02-36, H03- 56, H04-31, H04-33, H04-45 and HC-5 were assessed for various root characteristics under two environments – irrigated and rainfed. The sampling was done at full bloom. Under rainfed conditions, there were significant differences in the rooting depth among the genotypes. The chickpea roots penetrated to a maximum depth of 80 to 121 cm. The rooting depth remained higher under rainfed than irrigated environment. The genotypes HC-5 and H02-36 showed higher dry matter of roots, rooting depth, root : shoot ratio, yield and better plant water status and were directly associated with seed yield per plant and can be used in chickpea breeding for drought tolerance.
