Abstract:

Drought is considered to be one of the major abiotic stress factors that severely limit grain yield production, often causing extensive economic loss to agriculture. Improving drought tolerance in maize has become one of the top priorities in maize breeding programs. Identification of maize germplasm with superior drought tolerance is a prerequisite for such purpose. Out of a set of 35 inbred lines, nine inbred lines viz., UMARKOTE-3, CML-411, CML-122, CML-40, CML-27, CML-336, CML-191, CLO-2450 and CAL-1415 showed high tolerance to drought. Such inbred lines were able to maintain shorter anthesis-silking interval (ASI), higher shelling %, moisture%, cob length, cob diameter, 100 grain weight and comparatively higher grain yield when subjected to drought stress. In contrast, CML-161 and CML-300 showed exactly opposite trend as compared to those tolerant ones and these two recorded lowest grain yield among the inbred lines under water stress. The potential use of promising inbred lines that are able to alleviate the negative impacts of drought on growth and development, are underway for production of maize hybrids.
