Abstract

A field experiment was laid to study correlation and path co-efficient analysis for 14 traits. The genotypic correlation co-efficient were found to be of higher magnitude than the corresponding phenotypic correlation co-efficient in most of the cases. Grain yield was highly significant and positively correlated with number of tiller per plant whereas strong positive and highly significant correlation also exhibited by plant height at genotypic level however highly significant and negative correlation with protein content. Path analysis revealed positive direct effect via harvest index followed by days to heading, plant height, number of spikelet per panicle, gluten content, protein content, number of tiller per plant, number of grains per panicle and length of panicle on grain yield. Hence emphasis should be given to number of tillers per plant, and number of grains per panicle for genetic improvement of grain yield in wheat.
