Brassica genotypes representing four different species viz. B. nigra and B. campestris (both primary diploids), B. juncea and B. carinata (both allotetraploids) were examined for photosynthesis rate (Pn), ribulose-1,5-bisphosphate carboxylase (RuBPC) activity, leaf soluble protein and chlorophyll content. B. nigra is the male and female parent of B. juncea and B. carinata, respectively. B. campestris is the maternal parent of B. juncea. Pn was significantly higher in B. nigra and B. carinata compared to the other two species. These two species also sustained Pn of the leaves for a longer period during ontogeny. When B. nigra was the male parent, the higher Pn of B. nigra was not inherited in B. juncea. On the other hand, the Pn and pattern of ontogenetic changes in B. campestris and B. juncea were more or less similar. In specific RuBPC activity on soluble protein basis, chlorophyll and soluble protein content B. carinata also followed B. nigra whereas, B. juncea followed B. campestris. These results indicated the possible maternal(cytoplasmic) influence on the inheritance of these traits.
