Comparison of Yield and Rice Quality of Direct Seeding Rice Progeny Stable Lines Based on Principal Component Analysis
Rice yield and quality traits of 52 stable lines of direct progeny were analyzed.The results showed that the yield and quality traits of rice were separated in different degrees.In terms of yield,it needs to be improved,but it has great advantages in processing quality,appearance quality,nutrition and taste quality.The comprehensive evaluation function of rice quality traits was constructed by using principal component analysis to reduce the dimensionality of rice quality resources,and 5 materials with scores greater than 2.0 were selected.22DS045 scored the highest score(3.102),which provided the material basis for the research and innovation of new varieties breeding of resistant and good eating resistance live rice in coastal rice area of Liaoning Province.
