| 摘 要： | 研究了若干棉花品种(系)及不同组合棉花杂交群体的经济性状,分析经济性状与病情指数的相关性。结果显示:①海陆杂交群体的抗性比陆陆杂交群体的抗性普遍偏高;②陆地棉品种(系)病情指数与有效果枝、有效铃数呈显著负相关;③陆陆杂交群体M44株系的相对病指与有效果枝、铃数、有效铃数呈显著负相关;④海岛棉品种(系)相对病指和株高呈显著负相关;⑤海陆杂交群体M37株系的相对病指与株高和始节高呈显著负相关;⑥有效果枝和有效铃数可以作为对黄萎病抗性间接鉴定的指标。⑦海陆杂交后代中,与抗病性共同遗传的为株高,因此可将株高作为分子标记辅助抗病育种的参考。 |

| Abstract: | Several cotton varieties and two hybrid populations were used to analysis the correlation between resistance to Verticillium wilt and economic characters in cotton.The results showed that,(i) The hybrid population from G.hisutum and G.barbadense had the higher resistance than that of G.hisutum and G.hisutum.(ii) The disease index of G.hisutum had significantly negative correlation with the number of effective fruit-bearing branches and the number of effective bolls.(iii) The disease index of M44 had signifi... |
