Abstract:

Current research was conducted with the objectives to identify the utmost traits that may be beneficial for the higher productivity of the grains under stress environment. Research material consisted of thirteen genotypes which were obtained from different sources. Experiment was carried out in randomized complete block in a split plot design. Water regimes (irrigated and non-irrigated) were allocated to the main plots and genotypes to the subplots. Path coefficient could be used as an important tool to bring about appropriate cause and effects relationship between yield and yield components. According to obtained results the selection on the basis of number of spikes, number of spikeletís and number of grains in this material would likely to be most useful for increasing grain yield because of their direct positive contribution to grain yield under irrigated condition. However number of spikes, spikelet numbers, spike length and grains number may be used an effective selection criterion for increasing grain yield of wheat under different irrigation levels. Therefore it is concluded that these traits could be selected for the different stress environments and it would be beneficial for the yield.
