998、1 999年两年在麦盖提县对我国“863”项目选育一批转基因抗虫棉品种与对照进行了对比试验 ,调查评估了抗虫棉品种在新疆南疆棉区的丰产性、抗病性、抗虫性及适应性。结果表明 :丰产性在抗虫棉品种间及对照间差异较大 ,8个抗虫棉品种对二代棉铃虫具有较高的抗性 ,抗虫性在抗虫棉品种间有差异 ,但均优于对照 ;抗病性在抗虫棉品种间有差异 ,但均劣于对照 ,纤维品质、绒长均在 2 9mm以上 ,比强度 3号、5号抗虫棉品种和对照品种在 2 1 c N/tex以上 ,抗虫棉品种前期生长势不如对照 ,后期早衰
In 1999 and 1999, a series of comparative experiments were conducted on the breeding of a batch of transgenic Bt cotton varieties in the “863” project in Maitgei County in 1999 to investigate and evaluate the high yield of insect-resistant cotton varieties in southern cotton area of Xinjiang , Disease resistance, insect resistance and adaptability. The results showed that there were significant differences among high-yielding varieties and insect-resistant varieties. Eight varieties had higher resistance to second generation cotton bollworm, Which was better than that of the control. The disease resistance was different among insect-resistant cotton varieties, but both were inferior to the control. The fiber quality and cashmere length were all above 29mm. The specific resistance of cotton varieties 3 and 5 were 21 c N / tex above, the potential growth of insect-resistant cotton earlier than control, premature senility
