  • Abstract:
  • The present study entitled “Genetic analysis in local collection of Indian Mustard (Brassica juncea L.)” for estimating the degree of genetic diversity in the parents' respective yield and quality metrics as well as to find superior parents. To achieve these objective parents were conducted rabi 2022-23. Spacing of 30 X 10 cm2 was kept between row to row and plant to plant and 15 plants were raised in each row. Observations were made in days leading up to 50% flowering, plant height (cm), Numbers of primary branches per plant, Days to maturity, Numbers of silique per plant, Length of silique, Numbers of seed per silique, 1000 seed weight, Seed yield per plant. The results obtained were subjected to statistical analysis. All of the analyzed characters' mean squares resulting from genotypes were extremely significant i.e. 50% flowering, plant height (cm), Numbers of primary branches per plant, Days to maturity, Numbers of silique per plant, Length of silique, Numbers of seed per silique, 1000 seed weight, Seed yield per plant. This shows that the genotypes for these traits exhibit considerable genetic diversity. The estimate of high PCV and moderate GCV was observed for length of silique and number of branches per plant in TAM-108-1 and BIO-902, suggesting influence of environment. These characters are not expression its genetic potential. Moderate levels of PCV and GCV were obtained for days to flowering, 1000 seed weight, stem girth and average fruit weight indicating moderate level of variability for the said traits The estimates of high heritability value were noticed for plant height, number of branches, days to flowering, average fruit weight, fruit yield per plot, fruit length, fruit diameter, and Days to maturity in Pusa Agrani. High heritability indicates, a large number of fixable additive genes are present for the traits. It is also supported by the ratio of GCV and PCV, which also indicated the presence of additive genes for the characters.
