摘要: 利用AFLP分子标记技术对板栗短雄花序芽变及其母株进行了初步研究, 72种引物组合共产生5 129条清晰谱带, 多态性位点53个, 多态性2.05% , 相似性系数0.9897, 差异片段主要集中于300~900 bp之间。研究表明短雄花序芽变和对照个体之间变异与遗传物质的改变相关, 其中一些可能与雄花序变短的基因有关。

Abstract: AFLP was used to compare the short catkins sport and its mother plant in chestnut (Castanea mollissima Bl. ). A total of 72 selective primer pairs amplified 5 129 clear bands, of those 53 were polymorphic loci. The polymorphic rate and Neips association coefficient between them were 2.05% and 0.9897 respectively. The molecular weight range of the polymorphic fragments was mainly 300 - 900 bp. The results indicated that there were some molecular-level differentiation between chestnut and its short catkins sport. Some of the specific segments had been considered as markers of short catkins in chestnut.

Key words: Chestnut, Sport, Short catkin, AFLP
