我国青蒿初选核心种质的构建

Establishment of canditate core collection of Artemisia annua from China

目的:构建青蒿初选核心种质。方法:比较青蒿形态性状描述和SRAP分子标记相结合。结果:青蒿素含量、株高等8个形态标记性状的平均数、标准差、方差、变异系数等参数,与青蒿初始种质基本一致;观测等位基因数、有效等位基因数、Nei’s遗传多样性指数和Shannon’s信息指数等SRAP分子标记参数在0.01水平上与初始种质差异不显著。结论:本研究的青蒿初选核心种质能够代表初始种质的遗传多样性。

Objective:To establish the candidate core collection of Artemisia annua.Method:The morphologic traits and the results of SRAP marker were compared respectively.Result:The χ2 test and the t test of both indexes for 8 morphological characters and SRAP marker parameters did not reach significant level between the candidate core collection and the primary sample.Conclusions:In this study,the candidate core collection can stand for original collection excellently.
