The response of Brassica carinata hybrids and their parents to moisture stress at different growth stages was studied. B. carinata 226 was found to be susceptible to stress at pre-flowering and post-flowering stages while B. carinata 241 at flowering stage. Neither the changes in stomatal conductance nor in chlorophyll content could fully explain the reduction in net photosynthetic rate (PN) induced by stress. B. carinata 241 had higher leaf water potential (psi w) although, it had lower PN compared to B. carinata 226. Both the parents had lower PN as well as leaf psi w. The stress response of PN in hybrids followed that in their respective female parents.
