Abstract

The present experiment has been designed to study the correlation and path coefficient analysis to identify the important character(s) for selection under different environmental conditions. The fifty durum wheat genotypes were grown in simple randomized block design experiment (RBD) as timely and late sowing for two years. The estimates of genotypic correlation coefficients were higher in magnitude than the estimates of phenotypic correlation coefficients for almost all the character combinations in all the environments. The grain yield showed significant and positive association with tiller number, biological yield and harvest index in all the environments; with plant height in   E III and E IV; with days to maturity and 100 grain weight in E IV only. Path coefficient analysis identified biological yield and harvest index as most important characters which not only showed highest direct effect towards grain yield but almost all other character also showed indirect contribution towards grain yield via these two characters.
