Genetic components analysis in Indian mustard (Brassica juncea L. Czern. and Coss.)

Genetics components analysis exhibited over dominance for all the characters in both the generations except plant height which showed partial dominance in F1 and complete dominance in F2. The value of genetic component ( Fˆ ) were found positive for all the characters in both generations except number of primary branches and plant height in both the generations. The positive and significant values of Fˆ indicated that the dominant genes were more frequent than recessive ones in the parents for concerned character. The correlation coefficient (r) between parental order of dominance and parental measurement was not found to be negative for any character.
