光皮树（优良无性系）优树选择技术研究

On Selection Techniques of the Swida （Fine Clones）

本文根据江西省光皮树的自然分布和人工栽培状况，赣州市的于都、瑞金等部分乡镇有着悠久的栽培历史，光皮树自然变异类型很多，通过连续3年的选优，制定了光皮树的优树标准，初步选出了3个优良无性系，其果穗数、果德果粒数、百粒质童、饱粒率和抗虫性等性状均明显优于对照样。为生产单位发展与开利用光皮树提供优良种质资源和技术参考。

According to the natural distribution of trees and planting conditions of the Swida in Jiangxi Province, it has a long history of cultivation in Yudu and Ruijin area in Ganzhou in all, There are many types of natural variation of the Swida, and through 3 consecutive years of the optimal selection, developed standards for fine trees, and initially selected three fine clones, the number of spikes, fruits, seed weight quality, full grain traits and insect resistance rate are superior to the sample, which can provide excellent resonrces and technical reference for the developing and exploiting the Swida.
