Abstract:
The present investigation was carried out at Agricultural Research Station, Bailhongal, UAS, Dharwad during rabi-2018-19 in augmented design under well watered and water stress condition. Mutant populations (F2M2 and M2) of two bread wheat crosses along with control F2 were evaluated for nine yield traits and genetic variability parameters were estimated. The result of the study recorded increase in the range values for most of the yield traits in irradiated populations and the mean values increased from control F2 to F2M2 populations in both crosses for grain yield per plant, number of tillers per plant, number of spikelets per spike, spike length, days to 50 per cent flowering and days to maturity both under well watered (WW) and water stress (WS) conditions. High percent estimate of both genotypic and phenotypic variability coupled with high heritability for number of tillers per plant, 1000 grain weight and grain yield per plant was observed in F2M2 and M2 populations irradiated with 150 Gy and 200 Gy. Further, these populations could be expected as a source population for isolation of high yielding genotypes under rainfed/water stress condition.
