滇牡丹

滇牡丹是中国西南的特有植物，在中国植物红皮书中将其定为渐危种而列为国家二级保护植物。

Paeonia delavayi , an endemic species to Southwestern China , was protected as a vulnerable plant in China .

本文主要从形态性状、EST-SSR分子标记及孢粉学等方面对滇牡丹10个花色类群的遗传背景进行了研究，以期为制定正确的选育种策略和系统进化研究提供理论依据。

In order to provide a theoretical basis of breeding strategy and system evolution , the genetic backgrounds of 10 flower color groups were studied from the aspects of morphological characters , palynology characters and EST-SSR molecular marker in this research .

主要研究结果如下：（1）滇牡丹花色类群形态变异丰富。

The results were shown as follow : ( 1 ) The morphological variations were rich in P. delavayi flower color groups .

滇牡丹具丰富的花色变异，是一种极具观赏价值和开发潜力的野生花卉资源。

Because of the rich variations in flower color , P. delavayi is an excellent wild flower resource with ornamental value and development potential .

从表型、花粉形态及分子多层次综合分析，滇牡丹花色类群间虽有较高的遗传分化，但同一类群内个体间遗传多态性也较高。

The study was comprehensively analyzed from the aspects of morphology , palynology and molecular . The results showed that the genetic differentiations were high among the flower color groups , but the individual genetic polymorphism within the same group was also in high level .

综上推知：滇牡丹花色类群遗传多样性为中等水平，变异主要来自于类群内。（4）滇牡丹花色类群更宜作为多目标育种亲本。

It could be concluded that the genetic diversity of P. delavayi flower color group was in middle level ; the variation mainly came from intragroup . ( 4 ) The P. delavayi flower color groups would be more applicable as the multiple object parents of breeding .
