Abstract: The net photosynthetic rate(NPR),stomatal conductance,transpiration rate(TR),SOD activity,POD activity and MDA content were studied for cotton hybrid.The results showed that there were positive superparent heterosis for NPR and TR of F,and Fz,and for SC and SOD activity of F,and positive midparent heterosis for SC of F and POD activity of F,but negative midparent heterosis for MDA content of F.

Key words: Upland Cotton, Intervarietal hybrid, Net photosynthetic rate, SOD, POD, Stress-resistance
