Analysis of Quality Traits and Abundance and Stability of Rice Varieties in Liaoning Province
Based on the experimental data of 23 varieties in the middle and late maturing group of rice regional test in Liaoning Province in 2023,the quality traits,high yield and stability of varieties were analyzed.The results showed that the coefficients of variation of 11 quality traits ranged from 0.93％to 70.00％,and there were different degrees of correlation among them.Processing factor,amylose factor,alkali elimination factor,chalkiness factor and protein factor all affected the comprehensive performance of quality traits of varieties.The abundance and stability of 23 rice varieties were analyzed by using coefficient of variation,regression coefficient,high stability coefficient and variety yield.The results showed that high stability coefficient,regression coefficient and variety yield could better distinguish high yield and stable yield of rice varieties,and there was obvious negative correlation between high yield and stability parameters of rice varieties.On this basis,cluster analysis and variance comparison showed that Tianlonggeng-224,Liaogeng-169,Yangeng-66,Tianlonggeng-234,Tianlonggeng-788,Huageng-1607,Yangeng-945 and Liaogeng-1920 had better yield level and stability.
