Abstract

The greengram, also known as mungbean or Vigna radiata L. Wilczek, is a significant pulse crop in India. Throughout India, it is mostly cultivated in subsistence agricultural systems. Even though it may be cultivated in three seasons across India, the average production is unbelievably low. The local germplasm has a significant genetic variation since the crop has developed in a wide variety of environmental settings. To comprehend the genetic variability and identification of distinct germplasm lines, a study was conducted on 300 green gram accessions utilising 14 quantitative traits. For pods per plant, pod clusters per plant, branches per plant, biological yield per plant, 100 seed weight, nodes per plant, harvest index, and seeds per pod, relatively high PCV and GCV were found. Additionally, an evaluation of the genetic advance (GA) and broad-sense heritability (h2) was done to select the most significant quantitative variables. Due to their high broad sense heritability (h2) and genetic advance, biological yield per plant, pods per plant, plant height, and harvest index were shown to be highly suited for mungbean breeding programmes. The breeder must typically utilise an appropriate breeding strategy to use these traits in subsequent breeding programmes.
