Genotype x Environment interaction effects and the stability for grain yield was determined by evaluating eighteen wheat genotypes in three different sowing dates at AICRP on wheat, MARS, University of Agriculture Sciences, Dharwad (Karnataka) during rabi 2017-18 under irrigated conditions using a RCBD with two replications. The genotypes NIAW 34, HW 1098 and BMZ 15-16-2 showed higher grain yield (2965.7, 3131.5 and 3037.7kg/ha), average responsiveness (bi = 1) and non-significant S²di value which suggesting suitability of these genotypes for different dates of sowing. The genotype HW 1098 exhibited superior performance for yield contributed by high tiller under early sown conditions. The genotype HD 3090 recorded lower mean value with average responsiveness (bi=1) indicating, poor adoptability to different dates of sowing and suitable only for timely sowing. The genotypes, GW 322, UAS 415 and DDK 1029 showed higher mean values and bi > 1 indicating sensitive to environmental changes and specific adaption to early sowing. The genotypes BMZ 15-16-5 shows above average mean value and bi <1 indicated specific adoption to only early sowing conditions. Results inferred that the genotypes namely NIAW 34, HW 1098 and BMZ 15-16-2 suitable for all the three dates of sowing condition. It was also found that early sowing is the most optimum time for sowing of wheat crop.
