High-quality spring wheat strains Yield and Quality Traits genetic parameters and correlation of selected seven spring wheat, 14 important quality and yield traits genetic coefficient of variation, broad sense heritability, genetic correlation coefficients, the generalized correlation heritability and genetic parameters estimation and analysis, and to explore a comprehensive selection of economic traits of spring wheat. The results show that: (1) SDS-sedimentation value broad-sense heritability (75.81%), direct selection, genetic variation coefficient (5.22%) and the average performance (3.5918ml), to further improve the sedimentation value of the group , should be the introduction of new germplasm; the gluten mass index broad-sense heritability (87.43%), genetic coefficient of variation (25.97%), positively correlated with the sedimentation value, a major cause of sedimentation value differences. (2) flour protein content, grain protein content, wet gluten content of genetic variation coefficient of medium, high broad-sense heritability, phenotypic correlations and genetic correlations were highly significant, and the phenotype caused by genetic reasons. Grain protein content in the early generation late generation of flour protein content as those traits, cost-effective. (3) the yield and quality trait there is a contradiction, but mainly due to the conflict between the gluten quantitative trait, with no apparent contradiction in gluten quality traits. Correlation between analysis and protein yield and other traits heritability Path analysis showed that the genetic factors that affect protein production is biological yield, seed number per plant and protein content, the use the protein yield efficiency of indirect selection is greater than Direct selection efficiency, but the protein content of the main limiting factor, the choice should not be asked to strict. These three traits combined with sedimentation value, blowing bubble instrument parameters processing quality traits comprehensive selection, easy to get the yield and quality trait combination of better economic system. (4) the evaluation and selection of the important traits of seven spring wheat, the results showed that: line 032 yield and quality traits showed the best, it may be a signs of strain or at least a good germplasm; strains 342 512 Yield Traits and Nutritional Quality Traits performed better processing quality traits in general, its transformation may be relatively easy, it is recommended as a germplasm material; performance of other strains, eliminated or further investigation.
