摘要
对板栗主产区毕节地区开展优良品种和优株调查选择,应用Fuzzy二级线性加权变换模型进行分级后,将选出的板栗优株繁殖成无性系,开展无性系测定。最后选出Ⅰ级性状的优株无性系5个、Ⅱ级2个、Ⅲ级1个、Ⅳ级1个、Ⅴ级1个。
The clones of selected plus trees were tested after surveying, selecting and propagating plus trees of choice varieties for Chinese chestnut in Bijie area in main product area, these plus trees were classified by using the Fuzzy two levels linear weighting transformation model. The plus tree clone for class Ⅰ , Ⅱ,Ⅲ, Ⅳ, Ⅴ were selected 5,2,1,1,1 respectively.
