Abstract:
In the present experiment twenty-seven genotypes of Indian mustard are evaluated for thirteen quantitative and one biochemical trait for different measures of variability, inheritance and character association and path coefficient analysis. PCV and GCV analysis stated that traits such as SYP, TAW and NSB were high in both the parameters and the difference between the PCV and GCV value in all the traits were minute representing that involvement of environment in the expression of these traits were negligible. Traits namely DFF, DM, NSB, TAW, BYP, HI, SYP exhibited very high heritability as well as high genetic advance rendering these traits eligible for selection due to the existence of fixable component of genetic variance. Traits namely LMS, BYP, NSS and NSB were found to be significantly and positively associated with the trait SYP. In the path coefficient study, traits such as BYP, HI, NSMS, NPB, NSS, LMS, LSMS, OC, DFF and TAW revealed positive direct effect on the trait SYP which gives an insight of the magnitude of relationship with the trait of interest.
