The Study On The Reaction Of The Different Genotype In Spring Wheat In The Grades Of Density And Fertility

The 10 quality and agricultural characters of the 14 varieties of spring wheat in the different the grads of density and fertility have been comprehensively analyzed by several statistical means .The conclusion was showed as follows:1. The 5 quality indexes (wet gluten content, GMP, pelshenke velum ,sedimentation, crude protein content) are analyzed, Variances of GMP, wet gluten content ,pelshenke velum, sedimentation are terribly significant; The sensitivity of pelshenke velum is higher than that of other quality characters. The sequence of the sensitivity of the quality characters is pelshenke velum, GMP, wet gluten content, sedimentation, crude protein content.2. The variance of agricultural characters are terribly significant and the variance of different density is terribly significant, the variance of different fertilizer is terribly significant The The sequence of the sensitivity of the quality characters is plant height, thousand kernel weigh, ear length, available tiller, single plant grain weight3. Tthe correlativities of wet gluten content, GMP, pelshenke velum ,sedimentation ,crude protein content are terribly significant, and cumulative contribution rate is above 85%.So wet gluten content, GMP, pelshenke velum ,sedimentation ,crude protein content can decide the change of the different quality types of spring wheat.4. plant height, available tiller, thousand kernel weight, ear length are used to be independent variable and single plant grain weight is Y in order to do step- regress, the equation is :the equation has been proved by simple correlation on agricultural characters and can be used to prognosticate single plant grain weight.5. There are not necessary contact between plant length(61.529-110.14cm) and single plant grain weight.6. Investigation in agricultural and quality characters find that the properest combination of 5 agricultural characters is 200000/mu+30kg/mu.The properest combination of 5 quality characters is different each other .moreover it can detach the different genotypes of spring wheat.7. Clustering of quality prove that the properest combination of 5 quality characters is validity and Clustering of quality is a good way to sort spring wheat.8. The reaction of different genotype spring wheat to environment is different, so the most blunt variety can been elected ,ie ,6501 in order to gain high yield and quality at the same time.Ma Tingchen Crop hybrid breeding Prof. Li Zhuofu...
