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。

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.
