Abstract: Fifty durum wheat genotypes were evaluated in three replicated trials under timely and late sowing conditions during 2015-16. The Experiment was carried out to assess effects of heat tolerant traits on grain yield and their association under late sowing condition in durum wheat. The values of genotypic correlation in both sowing conditions (D0 & D1) were higher as compared to the corresponding phenotypic correlation. This indicated that though there was high degree of association between two variables at genotypic level, its phenotypic expression was deflated by the influence of environment. The character, grain yield per plant exhibited highly significant and positive genotypic and phenotypic correlation under D0 condition with harvest index, biological yield per plant and 100-grain weight, while it also manifested the highly significant positive correlation with length of main spike and plant height at genotypic level. The character, grain yield per plant under D1 condition exhibited significant and positive genotypic and phenotypic correlation with harvest index, biological yield per plant and plant height, while it also manifested the significant positive correlation with length of main spike and number of grains per main spike at genotypic level. The yield components exhibited varying trends of association among themselves. Thus, revealed that under D0 condition harvest index, biological yield per plant, 100-grain, length of main spike and plant height and under D1 condition harvest index, biological yield per plant, plant height length of main spike and number of grains per main spike were the most important traits and may contribute considerably towards higher grain yield.
