Genetic Variability of Quantitative Traits in Indian Mustard (Brassica juncea L.) Germplasm Lines

Type: article
Abstract: The family Cruciferae (Brassicaceae) includes Indian mustard (Brassica juncea (L.) Czern & Coss), which is grown across India and the rest of the world under the genus Brassica. It contains 24% protein and 38–42% oil. Rai (B. juncea), a variety of mustard and rapeseed, is highly prized by farmers for its higher yield and stronger resistance to heat, relative diseases, lodging, shattering, drought circumstances, and saltwater sodic environments. In 50 genotypes of Indian mustard germplasm lines, an experiment was carried out to evaluate the genetic variability, correlation, and path analysis of twelve quantitative parameters. The experiment used a randomized block design with three replications. The analysis of variance ratios showed that the traits analyzed had highly significant differences among the genotypes. This indicates that there is considerable genetic variability among the Indian mustard germplasm lines for the quantitative traits under study. In conclusion, this study provides valuable insights into the genetic variability, heritability and genetic advance quantitative traits in Indian mustard germplasm lines.
