Heterosis and inbreeding depression in interspecific crosses of upland cotton

Of the 15 crosses using 8 varieties of upland cotton (Gossypium hirsutum Linn.), 7 showed positive and significant heterosis for bolls/plant, 10 for boll weight, 11 for seed-cotton yield and 1 for ginning percentage over their parents. Highest heterosis for yield was due to increased vigour for boll...

Summary:Of the 15 crosses using 8 varieties of upland cotton (Gossypium hirsutum Linn.), 7 showed positive and significant heterosis for bolls/plant, 10 for boll weight, 11 for seed-cotton yield and 1 for ginning percentage over their parents. Highest heterosis for yield was due to increased vigour for bolls/plant. 'Reba B 50' x '9030 H 8 (M)' which showed high heterosis for bolls/plant, boll weight, seed-cotton yield/plant and ginning percentage would be used for heterotic breeding
