Path coefficient analysis between seed yield components and seed yield of Setaria sphacelata cv. Narok
摘要
Abstract
This paper used multi-factor split plot designed field experiment, through the correlation analysis, path coefficient analysis and stepwise regression analysis for seed yield components and seed yield. The result showed that the order of six seed yield components of Setaria sphacelata contributing to seed yield was florets/cm, 1 000 seeds weight, inflorescence length, fertile tillers/m2, spikelet numbers /cm and seed numbers/cm in sequence. So improving the florets/cm, 1 000 seeds weight and inflorescence length was the most effective way to increase seed yield. The next was to increase spikelet numbers/cm, florets/cm and fertile tillers/m2.关键词
