| 摘 要： | 将20个加拿大早熟玉米群体与4个我国主要种质类群的代表自交系按照NCⅡ设计组配80个测交组合,2006、2007年进行田间鉴定试验,研究引进群体与我国主要种质类群的杂种优势关系。结果表明,EP1、EP9、EP14、EP15、EP16和EP17群体单株产量等综合性状一般配合力效应表现较好;EP1、EP8和EP19群体属于塘四平头群,EP12、EP14、EP15和EP22属于Reid群,EP17、EP20、EP21和EP23属于Lancaster群,EP3、EP6、EP7、EP9、EP10、EP11、EP13、EP16和EP18属于旅大红骨群;加拿大早熟玉米群体与旅大红骨类群的杂种优势最强。 |

| Abstract: | Twenty early-maturing Canadian maize populations were crossed with 4 elite Chinese inbred lines to produce 80 combinations by NCII design. These hybrids were tested to study heterosis analysis between import populations and Chinese main populations in Harbin during 2006 and 2007. The results showed that EP1, EP9, EP14, EP15 and EP17 showed the better general combining ability effect in comprehensive traits; EP1, EP8 and EP19 were belonging to Sipingtou group; EP12, EP14, EP15 and EP22 belonging to PA group; EP17, EP20, EP21and EP23 belonging to Lancaster group; and EP3, EP6, EP7, EP9, EP10, EP11, EP13, EP16 and EP18 belonging to Ludahonggu group. The heterosis between early-maturing Canadian maize populations and Luda red group was showed the strongest. |
