Drought is a major abiotic stress that causes a great reduction in the yield of the key cereal crops including sorghum. As the crops are sessile, they evolved several drought tolerance component traits to combat the water stress. Among the drought adaptive traits, root architecture plays a major role in efficient capillary water absorption even under severe water scarce situations through early development and deep penetration of roots. Thus, introgression of root traits in the elite breeding lines would enhance the breeding efficiency for water-limited environments. |
