DEVIDAS PATEL, P.K. MOITRA and SUBHASH RAWAT. 2017. Genetic variability, correlation and path analysis in F1s of bread wheat (Triticum aestivum L.). Green Farming Vol. 8 (5) : 1067-1070 ; September-October, 2017
Ten parents and their 25 F1s of wheat were evaluated during rabi 2015-16 for genetic variability in respect of ten quantitative traits. The analysis of variance for experimental design revealed that the mean squares due to genotypes were significant for all the ten characters studied. High GCV and PCV were observed for number of spikes/plant, number of tillers/plant, grain yield/plant and biological yield/plant. High heritability coupled with genetic advance as percent of mean was observed for number of spikes/plant, number of tillers/plant, grain yield/plant and biological yield/plant. Grain yield/plant showed significant and positive association with number of tillers/plant, number of spikes/plant, biological yield/plant, harvest index and 1000 seed weight. The path coefficient analysis indicated that the highest positive direct as well as appreciable indirect influence were exerted by the days to maturity followed by number of tillers/plant, biological yield/plant and harvest index.
