花香A系列杂交水稻组合产量及米质性状相关及通径分析
Correlation and Path Analysis of Yield and Quality Traits of Rice Combinations from Huaxiang A
摘要
Abstract
By analyzing the data collected from 10 hybrid rice from Huaxiang A for rice regional test with the coefficient of the correc-tion and path analysis, the results indicated that there exist significant positive correlation between daily production and effective pan-icle number, plant height and panicle length, grain number per panicle and filled grain number of per panicle, respectively. And the contribution of daily production to grain yield is the largest, next for effective panicle number. The head rice rate and chalky rice rate, length/width ratio and chalky rice rate, length/width ratio and chalkiness degree are significant negative correlation. Accordingly, we can increase the yield of hybrid rice from Huaxiang A by improving the daily production and the number of effective panicle, extend-ing the growth period, reducing the plant height and panicle length properly. And in order to improve the grain quality, we should re-duce the length/width ratio moderately, so as to improve the grain filling efficiency, reduce the chalky rice rate and chalkiness degree, and improve the head rice rate.关键词
