Hybrid breeding in Brassica juncea is suggested as the best strategy to boost rape seed mustard production in India. Diversified male sterile and restorer lines are required for a strong sustainable hybrid breeding programme. Knowledge about the inheritance of male sterile and restorer genes are essential for this. We studied the genetics of fertility restorer gene which can restore the fertility in three different male sterile systems(mori, eru and ber)in B.juncea using nine different BC1F1 populations. Monogenic and gametophytic mode of inheritance was observed for all the populations except for the back cross population derived from Pusa Agrani (ber). It was observed that few minor genes influence the pollen fertility in all the back cross populations
