Abstract
The present study involved 100 treatments (10 parents, 45 F1s, and 45 F2s) arranged in a Randomized Block Design during the 2024 Rabi season at Student Instructional Farm (CSAUAT, Kanpur) in F1 and F2 generations of a 10× 10 diallel cross without reciprocal. The experiment included 10 parental lines (K-0307, DBW-187, K-1711, DBW-252, DBW-316, DBW-173, HI-1653, HI-1654, SONALIKA, and PBW-835). The strong positive connection between phenotypic and genotypic performance, as well as path correlation across crops, contributes in the selection of superior breeding lines. A total of fourteen quantitative features were observed. In the F1 generation, grain yield/plant was positively and highly significant at the genotypic level when compared to biological yield per plant, productive tillers/plant, spike length, and harvest index. At the phenotypic level, grain yield/plant was significantly positively linked with biological yield per plant, productive tillers/plant, grain weight per spike, and spike length. In the F2 generation, grain output per plant was exceptionally positive and significant at the genotypic level when compared to biological yield, productive tillers/plant, spikelets/spike, and spike length. At the phenotypic level, grain output per plant had a highly significant positive relationship with biological yield per plant, productive tillers/plant, spike length, and spikelet count per spike. highlighting their important and vital significance in influencing production.
