模糊信息综合评判方法在优质小麦品质评价中的应用

小麦品种(系)间综合品质的差异性取决于各品质性状的优劣及变异性.根据模糊数学原理,提出优质小麦品质模糊综合评判的三种变异性信息权重分配方法—变异系数赋权、信息量赋权与距优平方和赋权.按方法对陕西省11个育成小麦品种(系)品质综合评判结果为:>-λ0.65,为优质小麦品种,包括高优503、陕160、小偃6号、大粒878、陕优225;λ-<0.55,为低筋粉专用小麦,包括小偃7号、秦麦12号、陕354、荔丰3号.

The Application of Fuzzy Information Synthetically Judging Method in the Appraise of High-quality Wheat

The difference quality of wheat depends on wheat′s varied nature quality and variability of properties.According to fuzzy mathematics principle,this paper put forward high-quality wheat fuzzy synthetically judging method of three varied kinds information synthetically weight assign-varied coefficient weigh,information amount weigh,excellent from square sum weigh.According to this paper′s method,synthetically judging result to 11 of Shannxi Province wheat breed is that high-quality wheat variety value>0.65,including high excellent 503,Shan 160,XiaoYan 6,Heavy grains 878,Shan excellent 225;and low muscle powder special-purpose wheat′s value<0.55,including XiaoYan 7,wheat Qin 12,Shan 354,LiFeng 3.
