EVALUATION OF GERMPLASM FOR VARIABILITY IN BREEDING AND SEED YIELD TRAITS IN Brassica juncea (L)

The present study was undertaken to evaluate various Genetic parameters like Variability, Heritability, Genetic advance and Genetic advance percent as mean for twenty-six genotypes of Indian mustard (Brassica juncea) L. by using RBD design in Rabi 2018 – 2019 at Experimental farm of the lovely professional university, Punjab. High phenotypic and genotypic coefficient variation (PCV and GCV) was reported in number of secondary branches (38.98 and 33.82), harvest index (35.58 and 25.49), biological yield (35.40 and 30.24), seed yield per plant (31.02 and 29.18) and number of primary (24.04 and 20.83), High magnitude heritability was recorded in all most all characters except harvest index and seeds per silique. High genetic advance recorded for plant height (42.06), length of the main shoot (42.35) and biological yield (45.47), genetic advance percent mean recorded high recorded for all most all traits except days to first flower, whereas selection of above traits would help in the effective improvement on seed yield per plant.
