Preliminary Studies on Yield Heterosis of Red Leaf Cotton Hybrids Abstract£ºYield heterosis of 19 red leaf cotton hybrids made by three red leaf cotton materials with excellent synthetic properties as male parents crossed with 15 new Bt transgenic green leaf lines as female parents was studied. There was obvious heterosis for seed cotton yield, positive mid-parent and super-parent, and negative competitive heterosis for lint cotton yield. There was positive mid-parent heterosis for lint percentage and single boll weight, positive mid-parent, super-parent and competitive heterosis for boll numbers per plant, 4 hybrid combinations with excelent synthetic properties and their yield competitive heterosis increased above5%.
