在高密度条件下,对37个玉米杂交组合个体效应的产量正、负相关性状赋权值分析计算,并结合单株产量最终选出各性状相对良好的5个组合。结果表明,玉米强优势杂交组合1203、1207、1235、1230、1224有选育成超高产品种的潜力,可以进入品比试验及区试。
在高密度條件下,對37箇玉米雜交組閤箇體效應的產量正、負相關性狀賦權值分析計算,併結閤單株產量最終選齣各性狀相對良好的5箇組閤。結果錶明,玉米彊優勢雜交組閤1203、1207、1235、1230、1224有選育成超高產品種的潛力,可以進入品比試驗及區試。

In this study,with 37 different corn hybrid-combinations under high density condition,the positive and negative weights their individual effected yields are calculated and analyzed,then integrated with single plant yield,5 hybrid combinations of characteristic are identified. In conclusion,the hybrid-combinations of 1203,1207,1235,1230 and 1224,perform a strong potential for super-high yield,thus all of which could be taken for further variety comparison and plot experiment.
