| 摘 要： | 本文按16X3双因数交叉式遗传设计配置的48个单交种为材料，连续2年在云南农业大学试验农场进行了家系的抗病性评价试验，试验采用随机区组，4次重复；抗病性采用Jan W.Henfling的方法计算发病叶面积，并进行了配合力分析。结果表明：（1）马铃薯对晚疫病的抗病性主要由本决定。（2）一般配合力对于马铃薯抗晚疫病更为重要。（3）母本393085．5、391002．15、391002．6、391004．4号具有较高的一般配合力，父本一般配合力不高。（4）母本39328058号与父本392639．8具有较高的特殊配合力。本研究结果为抗晚疫病的亲本选配提供了重要依据。 |

| Abstract: | Estimation on resistance to late blight ( Phytophthora infestans ) of the 48 crosses potato clones was conducted with Line X tester experiment on the Farm of Yunnan Agricultural University from 1998 to 1999 RUDP and 4 REP have been used in the experiment Their resistance was analysed according to the method of Jan W Henfling The area under disease progress curve(AUDPC) was calculated and their combining ability of resistance to late blight was analysed The results show that their resistance is mainly from their female parents,and the G C A of parents are more important on resistance to potato late blight;the female parents,such as 393085 5,391002 15,391002 6, etc,had better G C A;there was a better S C A between the 393280 58 and 392639 8 These results provide an important basis for selecting the parents with resistance to potato late blight in breeding |
