以河北省棉花品种区域试验结果为数据源,分析了1997~2006年审定的62个春播品种的主要性状参数分布、不同年度审定品种的变化趋势及综合达标情况。结果表明:①产量和株高性状参数分布广泛,衣分、铃重、子指和果枝始节变幅较小,枯萎病指和马克隆值高频区接近育种目标;②随时间推移,产量、单株铃数、铃重、子指、纤维长度和比强度有提升趋势,马克隆值适中且基本稳定,枯萎病指变化不大,黄萎病指有所降低但仍然偏高;③纤维比强度和黄萎病指是品种达标的制约因子。
Taking the regional test results of cotton varieties in Hebei Province as the data source, the distribution of the main traits of 62 spring sowing varieties approved from 1997 to 2006, the changing trend of the examined varieties in different years and the comprehensive compliance were analyzed. The results showed that: (1) The parameters of yield, plant height and height were widely distributed. The amplitude of boll weight, boll weight, index finger and fruiting branch were small, and the fusarium disease index and micronaire high frequency region were close to the breeding target. (2) With the passage of time, , Boll number per plant, boll weight, index finger, fiber length and specific intensity tended to increase. Micronaire value was moderate and basically stable. Fusarium wilt did not change much, while Verticillium wilt decreased but remained high. Intensity and Verticillium wilt are the limiting factors for the breed compliance.
