Abstract:
This study was carried to analysis correlation in six wheat (Triticum aestivum L.) genotypes such as TJ-83, Kiran-95, NIA-Sundar, Benazir, Hamal and Sehar-2006 for nine different traits viz., plant height (cm), tillers plant-1, spike length(cm), spikelets spike , grains spike , seed index (1000-grain weight, g), grain yieldplant biological yield plant (g) and harvest index (%). The results revealed that genotypes differed significantly (P ?0.01) for plant height, tillers plant-1, spike length, spikelets spike-1, grains spike-1, grain yield plant-1, seed index, biological yield plant-1 and harvest index. The varieties Kiran-95 and Sehar-2006 showed maximum values in mean performance for different traits. The traits such as spike length, spikelets spike-1, grains spike-1 and seed index showed positive and significant correlations with grain yield plant-1; hence these traits may be given priority in selection. High heritability estimates were observed for plant height, tillers plant-1, spike length, spikelets spike-1, grains spike-1, grain yield plant-1, seed index, biological yield plant-1 and harvest index.
