dc.description.abstractThe objectives of present investigation were to determine the genetic variability, estimation of association between grain yield and its component traits and among themselves to find out the correlation with agro-meteorological parameters of 28 genotypes of wheat and triticale under two dates of sowing. Significant variability was observed among genotypes for all the traits under both the environments. Genotypes WH1105, WH1142, HD 3086, WHD 948 and TL 3004 have been found promising for grain yield under favorable environment. Grain yield per plant showed highly significantly and positive phenotypic correlation with biological yield per plant, harvest index, number of grains per spike and 1000-grain weight. The path coefficient analysis revealed that Biological yield per plant registered the highest direct and positive effects on grain yield per plant followed by harvest index. Nutrient uptake and use efficiency was higher in triticale and synthetic wheat under late sown conditions. Triticale and synthetic have a low value of HSI showing its low susceptibility to elevated temperature which can be utilized in heat tolerance breeding programme.en_US
