Current research was conducted with aim to identify the characters of utmost importance in irrigated
and non-irrigated conditions that may be used as selection criteria in a wheat breeding program. The
experimental material consisted of 13 wheat genotypes including 11 bread wheat advanced lines from two
different sources, 1 synthetic hexaploid and its durum parent. Stress was imposed by withholding irrigation at
three different growth stages of plant i.e. tillering, anthesis and grain filling. Experiment was carried out in a
randomized complete block in a split-plot arrangement. Water regimes (irrigated and non-irrigated) were
allocated to the main plots and genotypes to the sub-plots. Morphological traits were recorded including days
to heading, flowering, anthesis, physiological maturity, grain-filling period, flag leaf area, plant height, biomass,
number of spikes, number of spikelets per spike, spike length, number of grains, grain yield, harvest index and
1000-grain weight. According to obtained results heritability among the traits under irrigated and non-irrigated
conditions was estimated. Spike length exhibited highest heritability value of 0.89, 0.84 and 0.87 under
irrigated, tillering and grain filling stress whereas grain yield had highest heritability value of 0.76 under
anthesis stress. These traits therefore deserve more attention in future breeding programs for evolving better
wheat for stress environments.
