摘　　要：对不同抗虫棉品种间几个主要性状的差异显著性、遗传力及相关性进行了分析。结果表明:在不同品种间,生育期、果枝数等几个主要性状差异显著;遗传力大小顺序为:皮棉产量>霜前皮棉产量>株高>节位>生育期>果枝数;生育期与节位、霜前皮棉产量与皮棉产量呈极显著正相关,生育期与霜前皮棉产量、果枝数与节位呈极显著负相关。This paper analyses the diverse significance, hereditary strength and. dependence of several main characters among the varieties of different Bt gene anti-insect cottons. The result showed that the different breeding time and fruit branch numbers grade several main characters of Bt gene anti-insect cottons were remarkable difference in varieties; The size order of hereditary strength is： yield of ginned cotton 〈 yield of ginned cotton before the frost 〉plant height 〉festival location 〉breeding time 〉the boll-bearing branch numbers ; The festival location and breeding time, the yield of ginned cotton and yield of ginned cotton before the frost were extremely remarkable positive eorrelation; the breeding time and the yield of ginned cotton be fore the frost, the fruit branch numbers and festival location were extremely remarkable negative correlation.
