摘要
为改良玉米品种遗传性状,以19个玉米自交系为父本,德美亚3号的亲本为母本,采用NCⅡ遗传交配设计,对12个主要农艺性状的配合力及遗传参数进行分析。结果表明:产量性状一般配合力排名前三的为79呼、Mo17187和合344;杂种优势特殊配合力分析认为可以利用H21、绿983和K10改良6F576农艺性状,利用79呼改良9F592,也可以用Mo17187同时改良9F592和6F576。
In order to improve the genetic characteristics of maize varieties,in this study,the combining ability and genetic parameters of 12 main agronomic traits were analyzed by using 19 maize inbred lines as male parents,the parents of Demeia No.3 as female parents and NCⅡgenetic mating design.The results showed that,the top three general combining ability of yield traits were 79 Hu,Mo17187 and He344.The analysis of heterosis special combining ability showed that H21,Lyu 983 and K10 could be used to improve the agronomic traits of 6F576,9F592 with 79hu,or 9F592 and 6F576 with Mo17187.
