本试验对２个抗虫棉品系、５个抗虫杂交棉（Ｆ２）的抗虫性及其产量进行了比较研究，结果表明，这些抗虫（杂交）棉的抗虫性均明显优于对照泗棉３号，表现为高抗棉铃虫并兼抗红铃虫，抗虫性以２个抗虫棉品系稍好，而慈抗１、２、３号３个抗虫杂交棉（Ｆ２）也有较好的抗虫性，而且其皮棉产量极显著地高于对照泗棉３号和２个抗虫棉品系。这表明利用抗虫杂交棉可将高产与抗虫性统一起来，实现高产高效的目的
In this study, two insect-resistant cotton lines, five insect-resistant hybrid cotton (F2) of the pest resistance and yield were compared, the results showed that these insect-resistant (hybrid) cotton insect resistance were significantly better than the control Simian No.3 showed high resistance to bollworm and anti-pink bollworm, the insect resistance was slightly better in two insect-resistant cotton lines, and the three insect-resistant hybrid cottons (F2) Better insect resistance, and its lint yield was significantly higher than the control Simian 3 and 2 insect-resistant cotton lines. This shows that the use of insect-resistant hybrid cotton can be high-yield and insect resistance together to achieve the purpose of high yield and high efficiency
