| 摘 要： | 对黑龙江省20个常用自交系与国内主要代表系Mo17、B73、丹340和444组配的80个杂交组合的群体杂种优势效应进行聚类分析。结果表明,K10、7884-7聚为Reid群,吉846、合344、垦44、冬17和杂C546聚为Lancaster群,东6002、81162、黄早四和L105聚为塘四平头群,旅9、丹337和丹705聚为旅大红骨群,东46、7010、海014、甸11、冬96和东237聚为东北群,分析结果与育种经验吻合。

| Abstract: | Twenty maize inbred lines in Heilongjiang province were crossed with 4 test lines from main domestic germplasm and the heterosis group were classified according to their heterosis value. The result showed that line 7884-7 and K10 could be classified into the Reid group. Dong17, He344, Ji846, Ken44 and ZaC546 were belong to the Lancaster group. 81162, Dong6002, Huangzao4 and L105 were divided into Tangsipingtou group. Dan337, Dan705 and Lu9 were in the Ludahonggu group. 7010, Dian11, Dong46, Dong96, Dong237 and Hai014 were in the Northeast group. The results anastomosed with the breeding experience. |
