以转基因抗虫杂交棉9个（代号为 B1～B9）新组合和湘杂棉7号（对照）为材料，进行生育性状、光合特性、产量性状和品质性状等方面进行系统的比较分析。研究结果表明：各组合与对照在生育期、株高、果枝数方面无显著差异；B3的早熟性、结铃性、叶绿素含量、籽棉产量和纤维品质均优于对照；B5、B6、B9的籽棉产量与对照无显著差异，B1、B2、B4、B7、B8叶绿素含量偏低、皮棉减产，品质也略差。综合各方面的因素，B3叶绿素含量高，有利于光合产物生产和供应，且铃大，结铃性强、产量高，纤维品质优，符合湖南省棉花新品种审定的产量及品质要求。
以轉基因抗蟲雜交棉9箇（代號為 B1～B9）新組閤和湘雜棉7號（對照）為材料，進行生育性狀、光閤特性、產量性狀和品質性狀等方麵進行繫統的比較分析。研究結果錶明：各組閤與對照在生育期、株高、果枝數方麵無顯著差異；B3的早熟性、結鈴性、葉綠素含量、籽棉產量和纖維品質均優于對照；B5、B6、B9的籽棉產量與對照無顯著差異，B1、B2、B4、B7、B8葉綠素含量偏低、皮棉減產，品質也略差。綜閤各方麵的因素，B3葉綠素含量高，有利于光閤產物生產和供應，且鈴大，結鈴性彊、產量高，纖維品質優，符閤湖南省棉花新品種審定的產量及品質要求。

The paper took 9 new combinations of Transgenic Insect Resistant Hybrid Cotton (codenamed B1 ~B9)and Xiangzamian 7 (CK)as materials,fertility traits,photosynthetic characteristics,yield and quality traits and other aspects were system comparative analyzed.The results showed that compared with CK,there were no significant difference in growing peri-od,plant height and fruit branch numbers.B3 showed higher value in precocious,boll setting,chlorophyll content,seed cot-ton yield and fiber quality.the yields of B5,B6,B9 were no significant difference with CK,B1,B2,B4、B7 and B8 showed lower SPAD value in leaves,lower yield and poorer -quality .B3 showed higher SPAD value in leaves,was conducive to the photosynthetic production and supply,and the big boll,strong boll setting,high yield and quality of cotton in Hunan province to meet the requirement of the new variety registration.
