Unveiling Key Correlation Studies in Local Germplasm of Green Gram [Vigna radiata (l.) Wilczek]

The present investigation entitled “Unveiling key correlation studies in local germplasm of green gram [Vigna radiata (L.) Wilczek]” was conducted at Agricultural Botany section farm, College of Agriculture, Dhule during kharif-2022. The experimental material included 42 genotypes of mungbean which were evaluated in a Randomized Block Design (RBD) with two replications, representing different eco-geographic regions and the source of material was Assistant Pulse Breeder, Oilseed Research Station, Nimkhedi, Jalgoan and local collection from Dhagdaon, Akkalkua, Nandurbar of Maharashtra state. Genotypes were evaluated for twelve diverse characters and correlation coefficient studies were conducted. The weight of 100 seeds (0.5054), the number of seeds per pod (0.4168), the thickness of the pods (0.339), the number of clusters per plant (0.2602), the number of pods per plant (0.2232), and the seed output per plant were the most significant and favourable relationships. It has a negative and non-significant correlation with the number of pods per cluster (-0.0534), but a positive correlation with plant height (0.1748), pod length (0.1737), protein content (0.159), 50 per cent flowering (0.0282) and days to maturity (0.0071). Based on the results, the highest yield of mungbean may be obtained from genotypes with higher protein content, early flowering and ripening, maximum plant height, long and thick pod size, more seeds per pod, and superior seed weight.
