Abstract:
The current investigation was carried out during rabi, 2020-21 following Randomized Block Design (RBD) with two replications using fifty genotypes of wheat germplasm that were collected from Wheat Research Station, JAU through 19th High-Temperature Wheat Yield Trails under International Maize and Wheat Improvement Center, Mexico (CIMMYT). Accessions were screened for characters association and path analysis using 21 quantitative traits. Association studies unveiled the presence of significant and positive association of Grain yield per plant with Harvest index (%), Biological yield per plant, LWR at 45 DAS, Number of productive tillers per plant, LAR at 45 DAS, and LAR at 75 DAS implying them as major component traits towards grain yield. Besides, findings from path analysis manifested that Biological yield per plant and Harvest index% were the characters that displayed a true relationship with grain yield.
