    Effect of pickings on seed quality in cotton (Gossypium hirsutum and Gossypium arboreum)
    (CCSHAU, 2005) Sasan, Ashish Kumar; Duhan, J.C.
    Seed quality plays an important role in crop establishment and overall performance of the crop. Four picking stage viz. First, Second, Third, Fourth of the eight varieties/hybrids viz. AAH-1, HD-107, HD-123, HD-324, HHH-223, H-1098, H-1117, H-1226 of cotton (Gossypium hirsutum and Gossypium arboreum) were evaluated by various tests viz. Standard germination, Seedling length, Seedling dry matter, Vigour index-I, Vigour index-II, Dehydrogenase activity test, Electrical conductivity, Seed index, Seed density, Tetrazolium test in the Department of Seed Science and Technology at Chaudhary Charan Singh Haryana Agricultural University, Hisar during 2003-2004. The quality of second picking seed was found significantly better as comparision to other pickings in all varieties/hybrids except seed index which was observed superior in the first picking seed.AAH-1 in desi cotton and HHH-223 variety in American cotton were found superior in seed quality and storability as compare to other varieties. In desi and American cotton AAH-1 and HHH-223 in second picking were recorded significantly higher interaction effect as compared to other combinations (pickings/varieties). These seed lots of various pickings were accelerated aged at 42±1oC for 72 hrs. for predicting the storability. The storability of second picking seed was observed significantly better as comparison to other pickings in all varieties / hybrids. AAH-1 in desi cotton and HHH-223 variety in American cotton wee found superior in storability as compare to other variation.
