Abstract:

The Experiment was conducted at Agriculture Farm, Nana Ji Deshmukh New Agriculture Campus, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna to evaluate the thirty two genotypes/varieties under normal soil and rain fed condition. The experiment was laid out fallowing Randomized Block Design (RBD) with three replications during Kharif 2018. The seed yield kg/ha showed significant and positive correlation with pods/plant, secondary branches, 100-seed weight and primary branches exhibited positive correlation coefficient with seed yield kg/ha at genotypic level. The seed yield kg/ha exhibited highly significant and positive correlation with pods/plant, secondary branches and 100-seed weight exhibited positive correlation coefficient with seed yield kg/ha at phenotypic level. The characters showing significant positive correlation among yield and yield components suggested that selection would be highly effective and efficient in improving these traits. phenotypic coefficient of variation was higher than genotypic coefficient of variation. Maximum phenotypic and genotypic coefficients of variation were observed for seed yield kg/ha and number of no. of primary branches. This indicated the presence of high magnitude of genetic variability in the material for these characters.
