ABSTRACT
In the present study, a set of 48 genotypes (including 10 lines, 4 testers, and 34 cross combinations) were evaluated to assess the stability for grain yield per plant, biological yield per plant, 1000 grain weight, number of spikelets per ear, sedimentation value and protein content (including 4 checks i.e. GW-322, GW-366, LOK-1 and MP-3269) across three environments in bread wheat. The variance due to genotype x environment was found highly significant only for sedimentation value. The genotype JW-1201 X MP-3269 exhibits stable performance showing potential for high grain yield per plant (30.35g), biological yield per plant (65.09g), and protein content (14.62%). The genotype HI-1544 X JW-3288 shows fair stability and potentiality for grain yield per plant (29.06g) and biological yield per plant (67.63g), even showing suitability for unfavorable environmental conditions for 1000 grain weight (41.10g), sedimentation value (56.24ml) and protein content (14.32%). Further genotype HI-1544 X MP-3269 was found to be suitable for adverse environmental conditions for 1000 grain weight (46.41g), number of spikelets per ear (20.48), grain yield per plant (25.32g), sedimentation value (60.7ml) and protein content (14.57%) showing its above-average stability. Thus, these genotypes can be utilized in breeding program for improving grain yield and its quality traits in bread wheat.
