摘要
结合2002～2004年3年来参加国家高梁区试春播晚熟组的高粱杂交组合在各承试点的产量及有关性状的调查数据，综合运用方差分析、相关分析、通径分析等多种统计方法，对高粱杂交种的产量及其重要农艺性状间的相关性和性状的遗传特性进行了细致和全面的比较分析和评价。通过这些比较和分析，总结出了高产杂交种所应具备的特征特性，为今后高梁的育种、栽培、推广提供一些有益的参考。
In this paper, yield and relevant traits of sorghum hybrids tested in 2002 - 2004 national sorghum regional .trails were studied. The correlation and genetic characters among yield and relevant traits of these sorghum hybrids were analyzed and evaluated by using a lot of statistical methods, such as analysis of variance, analysis of correlation and Path analysis. Through these analysis and evaluation, concluded what characters the good hybrid ＂should possess. So that can provide some useful suggestions and conference for sorghum breeding, culture and popularization.
