[ Method] The morphological and anatomical characters of stems of 10 rice varieties （including 3 internedes） were systematically studied by paraffin sectioning technology; the digital force tester was used to measure the compressive strengths of various varieties; the correlation between various characters and stem compressive strengths was analyzed. [ Result ] Correlation analysis showed that the outer diameter and cress-sectional area of stem had clese relation with longing resistance of stem, which could be adopted as the important factors for stem lodging resistance. The outer diameter and cross-sectional area of 63 Liangyou 636 was significantly higher than other tested varieties, 3 intemedes all had high comoressive strength, and the vleld was also high. [Conclusion] 63 Liangyou 636 could be used as the rice cultivar with super yield.展开更多
