摘要
以海岛棉亲本及杂交后代为试验材料,研究海岛棉杂种优势空间分布,结果表明:海岛棉籽棉重量、皮棉重量、单铃重、铃数均具有中部优势,7～10节位表现突出;海岛棉各节位的籽棉重、皮棉重的杂种优势呈负向优势,杂种后代在各节位铃数少是杂种优势负向的主要原因。
Using parents of island cotton and its hybrids as test materials, we have studied the spatial distribution of island cotton beterosis. The results showed that： seed weight, lint weight, boll weight, and the boll number have central advantage, 7 to 10 section performed significantly, seed weight, lint weight, boll weight in every section position hetcrosis behave negatively advantage, the less boll number of hybrids is main reason which heterosis negative.
