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
