Comprehensive Analysis On Quality And Agricultural Characters Of Spring Wheat

Quality and agricultural characters of 21 spring wheat distinct varieties are comprehensively analyzed to discuss the relation of high-yield and high-quality: Principal component analysis was used to analyze the main qualities indexes mat affect the varieties. Fuzzy clustering was used to sort these varieties. Harmonizing index was used to describe quamtively the typical characteristics of every categcry. Linear equation of GMP and crude protein content was used to predict the bread bulk. The conclusion was showed as follows:1. The variance of sk quality indexes (wet gluten content, GMP, bread bulk ,pelshenke velum sedimentation ,crude protein content) are analyzed, except wet gluten content, Variances of GMP, bread bulk, pdshenke velum, sedimentation are significant; the variance of six agricultural character indexes(plant height, spike length ^maE spike numbers of main spike, available tiller .thousand kernel weight) are analyzed, except the plant height, available tiller, the differences of others are significant All these illustrate that the difference of varieties was significant2. GMP, bread bulk, pelshenke velum sedimentation .crude protein content affect the quality largely Among these, the principal choice indexes are GMP, bread bulk, and not wet gluten content3. Linear equation of GMP c and crude protein bread bulk was used to predict bread bulk Y=2.2785+0.7216**X2 +0.08692X, 3.4.1Analyze the equation further to simplify itY=0.73549** X2 +2.646 3.4.2(X2; crude protein content X1: GMP Y: bread bulk)The equation (3.4.2) may predict bread bulk4. The 21varieties are sorted 4 categories by fuzzy clustering,: Glany was proved to be one category: Dong 6501, Q16, Roblin belongs to one category; Xmke9,Ke88-843,Bai yonglian4,Xinchun8 turn into one category ,and the others are sorted to one category.5. Harmonizing indexes of quality, Agricultural characters, agricultural-quality are used to sort the varieties, the result was resemble to by fuzzy clustering .so, me harmonizing indexes of varieties can estimate quantivery varieties and may be one of the main oiterions to choice high-quality varieties. According the harmonizing indexes of quality, agricultural characters, agricdtural-quality quality, agricultural characters, agricultural-quality, the 21 varieties are sorted to 4 categories .The equation of die classification are listed below:(1) Harmonizing index of quality of quality was small, Harmonizing index of agricultural characters are small, The mathematic model was :Y=0.2906*x1+0.08248x2+0.11575 3.5.1(2)Hannomzing index, of quality was large, Harmonizing index of agricultural characters was small, The mathematic model was :Y=0.6174**x1+0.1187x2-0.0005667 3.5.2(3)Harmomzmg index of quality Harmonizing indexes of quality was small, Harmonizing index of agricultural characters was large, The mathematic model was :Y=0.51685x1-H).31472x240.0551063 3.5.3(4)Harmonizing index of quality was small, Harmonizing index of agricultural characterswas large.6. Through the analysis of this paper, I find that high-yield and high -quality can improve at the same time.
