| 摘 要： | 采用不完全双列杂交设计,对玉米主要性状进行配合力效应分析。结果表明:不同自交系所表现的配合力不同,同一自交系不同性状间和同一性状不同自交系间的配合力存在一定差异;自交系昌7-2、太100、黄早四、05008都是较好的亲本,均可配制出高产的优良组合,其中,昌7-2、太100作父母本均可,黄早四、05008适宜作母本,054092需进一步改良。从产量构成因子配合力分析结果可以看出,尽管不同自交系不同性状的配合力有差异,但根据各因子配合力总和可知,昌7-2、黄早四、太100是高配合力自交系。

| Abstract: | With incomplete biserial row cross design,efficiency analysis of the main yield components combining ability in maize was conducted.Results showed that various inbreed lines had different combining abilities,or even various traits in an individual line or the same trait between lines also showed some difference.Four inbred lines Chang 7-2,Huangzaosi,Tai 100,05008 were fairly good parents,so could be used to make fine high-yield combinations.Namely,both Chang-72 and Tai 100 could be used as male or female pa... |
