摘要
Abstract
[Objective] To explore the correlation between rice yield and its related characters.[Method] We took the representative 44 plots as the sample points,the paper collected the related traits affecting the yield of rice,and divided it into yield-related traits and agronomic traits,systematically useds simple correlation,complex correlation and canonical correlation analysis.[Result] It had a strong correlation between yield and yield-related traits,among which the correlation between spike number and spike grain number was the strongest,the correlation between yield and agronomic trait group was not significant,but the agronomic trait group could indirectly affect the yield by yield-related trait group.In a certain range,the more secondary branches,the shoter length of flag leaf,and the higher yield.[Conclusion] In actual production,increasing both effective panicle number and grain number per area is the basic way to capture high yield and super yield,but to achieve more high yield in a high level,the key is to increase the number of grains on the basis of enough spikes.关键词
