Variability in groundnut for end-of-season drought tolerance


Author(s): Chandrashekhara G, Hasanali Nadaf and Harish Babu BN

Abstract: Groundnut is one of the leading oilseed crops, primarily cultivated for edible oil and protein in arid and semi-arid regions of the world. Drought is the most significant constraint that severely affects the pod yield and growth related traits in groundnut. The present study aims at assessing the genetic variability in groundnut genotypes to terminal drought tolerance The forty groundnut genotypes including advanced breeding lines and existing cultivars were evaluated under irrigated and drought stress conditions during Rabi 2016-17 at the College of Horticulture, Hiriyur using two sets of randomized completely block design with two replications. The results revealed the highly significant differences for all traits studied among the genetic stock indicating the remarkable levels of variability existed among the investigated genetic material that are very essential in groundnut improvement for terminal drought tolerance. The genotypes SB-14, ICGV 15141 and ICGV 15145 were observed better for terminal drought tolerance with high pod yield. It is suggested that these genotypes could be grown under regions of limited rainfall and may be used as parents in breeding programs for developing drought tolerant groundnut cultivars.
