Abstract

In a study to estimate the genetic variability, heritability, genetic advance and corre lation coefficients for eight quantitative characters and path coefficients for yield components in wheat (Triticum aestivum L.). the highest genotypic and phenotypic coefficient of variation was observed for yield per plant whereas the high heri- tability along with high genetic advance was observed for plant height. 100-seed weight. yield per plant and number of kernels per spike. Yield per plant had strong positive correlation with number of tillers per plant. length of spike, number of kernels per spikelet and 100-kernel weight. 100-kernel weight was highly and positively correlated with length of spike and spikelets per spike at genotypic level. number of spikelets per spike was highly correlated with length of spike and kernels per spike, kernels per spike and plant hoight with number of tillers per plant and length of spike: kernels per spikelet was strong- ly and positively correlated with kernels per spike. In path coefficient analysis, the length of spike seemed to make higher contribution to yield per plant as it gave the highest direct positive effect.
