Stability analysis for yield and yield related traits in advance breeding lines of chickpea (Cicer arietinum L.)

An experiment was carried out during Rabi 2018-19 at three locations (Nandyal, Gulbarga and Vijayapura) in Southern India to identify high yielding and stable chickpea genotypes for cultivation in South Zone. At each of the locations, the stability and adaptability of 35 advance breeding lines and two checks viz., JG 11 and JAKI 9218 were tested in a Randomized Block Design with three replications. Highly significant genotype × environment interaction was evident for days to 50 percent flowering, days to maturity, 100 seed weight and seed yield. Among three locations, Gulbarga was the most favourable environment for expression of the traits. The study identified BDNG 2017-1, RKG 13-22, RVSSG 67, DBGC-2 and DC 17-1111 as stable genotypes which can be recommended for all the three locations where as NBeG 798, BG 4001, PG 215, CSJ 1065, H15-27, RG 2016-134, DC17-115 and ICCV 171117 are appropriate for favourable environments.
