摘要： 笔者对3个陆地棉抗虫品种在两年间的农艺性状和纤维品质性状进行了研究。结果表明，3个抗虫棉品种的产量性状年份间表现基本一致，而纤维品质性状差异较大。新棉33B在3个抗虫棉品种中产量性状表现最好。品种与年份的互作极为显著，2002年新棉33B在籽棉产量和皮棉产量上显著高于对照品种中棉所12号，而在2003年则与对照品种产量相当。JS166在单株籽棉产量和单株皮棉产量、单株铃数、单铃重等性状上两年间表现均较好，2003年还有较低的蕾铃脱落率。99035两年间在产量性状上与对照相比略有提高，但差异并不明显。所有3个抗虫棉品种2002年的纤维品质指标与对照相当，而2003年纤维长度和纤维整齐度明显高于对照。

Abstract: The objective of this study was to find if there were any differences among three Bt transgenic varieties with insect-resistance in two years. The Bt transgenic varieties with insect-resistance showed the similar trend in both seed cotton yield and lint yield in 2002 and 2003 while they showed significantly difference in fiber characters. Among the three varieties, Xinmian 33B was the best in the yield. The interaction of variety and year was obvious. Xianmian 33B yielded higher than the Check, CCRI12 in 2002 while it got similar yield with the Check in 2003. JS166 was better in seed cotton yield, lint yield, boll number per plant and boll size in two years. Moreover, JS166 got lower percentage of boll shedding in 2003. 99035 obtained the same yield as the Check. In 2002 all three Bt transgenic varieties with insect-resistance had similar fiber characters with the Check while in 2003 the fiber length and fiber uniformity were better than the Check.
