Abstract
The present investigation was carried out as a field experiment for the evaluation of fifty genotypes for various traits and multivariant analysis. The research aims to study correlation between grain yield and its yield-contributing characteristic. The investigation was carried out at the Bajara Research Scheme, College of Agriculture, Dhule in 2021. Correlation studies revealed that grain yield per plant showed a significant positive association with traits such as plant height, productive tillers, panicle girth, panicle length, and test seed weight. While iron and zinc showed a non-significant positive genotypic correlation; negative correlation with days 50 percent flowering, days to maturity, and protein content. Analysis of direct and indirect effects for effective selection.
