树莓遗传资源的形态多样性研究

Study of Morphological Diversity on Genetic Resources of Raspberry

在保加利亚保存的树莓遗传资源有126个品种,其中9个是保加利亚的品种（1999～2001）。通过对树莓的形态多样性,供试材料的生物和经济性状的综合评价,获得了枝条的数量、高度和粗度,枝条上结果枝的数量,结果枝上浆果的数量等主要数据,这些数据可以确定用于育种的原始材料的优劣。

There were genetic resources of the raspberry 126 cultivars, 9 of which were Bulgarian （1999 2001）. After investigated the morphological diversity,biological and economic qualities of the samples, the main data of number of shoots,height and thickness of the shoot,number of fruit-breeding branches per shoot,number of fruit on a fruit-breeding branch were acquired,which could be used to establish the quality of initial materials in breeding.
