Abstract:

The Experiment was carried out to assess genetic variability with respect to grain yield and its components for heat tolerance in durum wheat. The values of phenotypic coefficient of variation in both sowing conditions were slightly higher than that of genotypic coefficient of variation for all the traits studied, indicating less effect of environment on the expression of characters studied. The genetic advance at 5% selection intensity (k=2.06) was found high under D0condition for number of grains per main spike, harvest index and biological yield per plant. Under D0 condition moderate genetic advance was observed for days to 50% flowering, plant height, grain filling period, days to maturity, chlorophyll content at anthesis (CHLa) and grain yield per plant, while under D1 condition for number of grains per main spike and harvest index. High heritability coupled with high genetic advance expressed as percentage of mean were observed for all characters except under D0condition for days to maturity, plant height and length of main spike, while under D1condition for days to maturity, grain filling period, length of main spike and 100-grain weight, which may be attributed to the preponderance of additive gene action and possessed high selective value and thus, selection pressure could profitably be applied on these characters for their rationale improvement.
