The present investigation was carried out at the Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar using forty-four diverse bread wheat genotypes. These were sown and evaluated under timely sown condition, in a randomized complete block design with four replications during Rabi 2019-2020. In the present investigation, 11 morphological and 2 biochemical traits were analyzed. The analysis of variance revealed significant variation among the genotypes for all the studied characters indicating the presence of adequate amount of variability among forty-four genotypes. High heritability associated with high genetic advance as percent of mean was found for the number of tillers per meter, the number of grains per spike, grain yield per plant, leaf area per plant, and peduncle length indicating the traits were simply inherited in nature. Higher values of genotypic correlations than their corresponding phenotypic correlations were recorded for all the studied characters. The path coefficient analysis revealed that the harvest index recorded the highest direct effect towards grain yield per plant, followed by plant height, the number of grain per spike, and protein content. It can be summarized that forimproving the grain yield in wheat; more attention should be given to harvest index, grain yield per spike, protein content, days to heading, and spike length while making the selection for developing high yielding wheat genotypes under timely sown condition.
