转基因芸苔属作物营养生长速率等级评判模型的构建

An evaluation model for ranking the vegetative growth rate of transgenic Brassica crops

基于模糊集重心理论及熵值法构建了转基因芸苔属作物营养生长速率等级评判模型,该模型包含确立评价指标正态隶属函数、利用模糊集重心理论计算指标重心向量集、利用熵值法计算评价指标权重向量和营养生长速率等级划分4个基本步骤.以一常规杂交组合试验的营养生长指标测量值为例对该评判模型进行了演示,论证了该模型具有可操作性.

An evaluation model of transgenic Brassica crops was proposed based on the theory of barycenter of fuzzy set and entropy method.The model included four steps as follows： the normal membership function establishment of evaluation indexes,calculating index barycenter vector set by the theory of barycenter of fuzzy set,calculating index barycenter by entropy method and identifying the rank of vegetative growth rate.Subsequently,the evaluation model was demonstrated in a case of cross combination experiment,which was proved to be operational.
