Abstract:
Sixty-four genotypes including sixty mutants of F4 generation derived from mutation breeding of Parbhani Moti using different treatments and four checks were evaluated for correlation and path analysis in Rabi 2020-21 at Cotton Research Station, Nanded, VNMKV, Parbhani. These mutant lines were grown in RBD with two replications and a plot size of four meters. These mutant lines were collected from the Department of Agricultural Botany, College of Agriculture, Parbhani, VNMKV, Parbhani in collaboration with BARC, Mumbai. From the experiment, it has resulted that grain yield had a positive and significant correlation with plant height, leaf area, stem girth, panicle length, panicle weight, fodder yield per plant, and biological yield per plant, while it had a significant but negative correlation with days to 50 % flowering, days to maturity, internodal length, 1000 grain weight. From these results, it can be said that these traits can be utilized for a further breeding program in grain yield as a prime objective. In genotypic path analysis, characteristics like days to maturity, plant height, stem girth, panicle breadth, fodder yield per plant, biological yield per plant, harvest index, iron content, and protein content positively affected grain yield per plant. However, characters days to 50 % flowering, leaf area, internodal length, panicle length, panicle weight, 1000 grain weight, and zinc content recorded negative direct effects on grain yield.
