摘要
应用灰色系统理论中的关联度分析方法,对福建省上杭白砂林场马尾松实生种子园子代测定林分的调查结果进行家系综合评选。通过马尾松家系多性状的关联度分析,评选出材积生长量高且结实性状好的家系37个,材积生长量中等且结实性状好的家系10个,材积生长量高且结实性状中等的家系7个。
The family comprehensive selection was conducted on the investigated results of progeny test stand of Pinus massoniana seedling seed orchard of Shanghang Baisha Forest Farm of Fujian Province with the correlation degree analysis method of grey system theory.Through the multicharacter correlation degree analysis of P.massoniana family,37 families whose volume growth was high and whose fruitbearing character was good,10 families whose volume growth was moderate and whose fruitbearing character was good as well as 7 families whose volume growth was high and whose fruitbearing character was moderate were selected.
