摘要: 对甜玉米含糖量与各农艺性状间进行了通径分析,结果表明:各农艺性状对含糖量的作用由大到小排列顺序为千粒重>穗长>行粒数>穗位高>穗行数>产量>株高>穗粗>生育期>出籽率。其中,千粒重对含糖量的直接通径系数达到p=1.5007,因此要提高含糖量应着重注意千粒重的选育。

Abstract: Path analysis of sugary content and characters traits in sweet maize,the results shows that the most contribution to sugary content is from 1000-seed weight,the following is ear length,kernel number/row,ear height,row number/ear,yield,plant height,ear width,growth period and shelling percentage.Among them,directly path coefficient of 1000-seed weight with sugary content was 1.5007,when selecting high sugary content of sweet maize,we must pay more attention to select the sweet maize of 1000-seed weight in high weight.

Key words: Sweet maize, Agronomic trait, Path analysis
