摘要:

为了从80份美国解禁自交系中筛选出配合力优良的自交系,分析其自交系利用潜力,为其合理利用提供依据。以PH6WC、PH4CV为测验种,采用NCII遗传交配设计,对80份美国解禁自交系进行配合力测定及对照优势分析。结果表明,80份美国自交系遗传基础丰富,存在真实差异,可将其分为33份母本群和47份父本群;80份供试材料中LH206、PHN66、NL001、2FACC、6M502A、29MIBZ2、1538、LH128、LH181、Lp215D、PHR30、LH214、LH213产量GCA效应值表现优良;杂交组合中PH6WC×6M502A、PHW51×PH4CV、NL001×PH4CV和LH128×PH4CV的产量TCA效应值表现优良,对照优势较强,可以进行下一步试验。80份材料中NL001、2FACC、29MIBZ2、1538适宜机械收获,性状GCA表现优良,6M502A、NL001、LH128一般配合力较高,可作为重点自交系利用。

Abstract:

In order to screen out maize inbred lines with excellent combining ability from 80 declassified inbred lines of the United States, analyze their utilization potential and provide the basis for rational utilization, we used PH6WC and PH4CV as test varieties to explore the combining ability and comparative advantages of the 80 maize inbred lines by NCII genetic design. The results showed that the genetic basis of the 80 American inbred lines was rich and there were real differences. The materials could be divided into 33 female parent groups and 47 male parent groups. Among the 80 test materials, LH206, PHN66, NL001, 2FACC, 6M502A, 29MIBZ2, 1538, LH128, LH181, Lp215D, PHR30, LH214 and LH213 had excellent GCA effect value for yield. The TCA effect values of PH6WC×6M502A, PHW51×PH4CV, NL001×PH4CV and LH128×PH4CV in the cross combination were excellent, and their comparative advantages were relatively strong, so further test could be carried out. The NL001, 2FACC, 29MIBZ2 and 1538 were suitable for mechanized harvesting, and the GCA showed excellent performance. Also, 6M502A, NL001 and LH128 had relatively high general combining ability, and they could be used as key inbred lines.

Key words: maize, American inbred lines, combining ability, yield, comparative advantages
