摘要
本试验在交城骏枣自然分布区进行资源调查的基础上,经初选、复选、决选,选出优良单株12株。应用模糊数学综合评价选优法,选出最佳优良单株5号,可供繁殖推广。主成分分析表明决定优良单株的基本指标为:丰产性状、Vc、含糖量和可食率。
Based on the resources of the Ziziphus jujuba cv. Jiaochengjunzao in its natural distributed area Jiaocheng county, Shanxi province. 12 superior trees were selected by the methods of preliminary selection, secondary selection and final selection. Through the application of fuzzy mathematics comprehensively estimating optimization method, the tree No. 5 was chosen as the best one and could be reproduced and extended. In addition, the principal component analysis shows that the basic indexes for a superior tree are fruit productive traits, rate of flesh weight to fruit weight, Vc content, sugar content.
