Abstract: The aim of this study was to systematically compare branch prickles, leaf prickles and fruiting characteristics of ‘Danlin No.1’ and ‘Danlin No.2’, which were selected as test Zanthoxylum armatum DC. materials with fewer prickles. The results showed that (1) the prickle number, prickle width and prickle length-width ratio of ‘Danlin No.1’ and ‘Danlin No.2’ were significantly different from the control, and the differences between them were not significant. The number of prickles on branches was 72.72% and 70.91% lower than CK respectively. There were significant differences among ‘Danlin No.1’, ‘Danlin No.2’ and CK at prickle length and prickle distance. The prickle distance was 81.14% and 37.96% higher than CK respectively. (2) The number of compound leaf leaflets of ‘Danlin No. 1’ and ‘Danlin No. 2’ was three at most cases, with no prickle on leaves and rachis. But CK compound leaf leaflets were mainly five, with tiny leaf prickles. (3) There were significant differences in ear length and ear width among ‘Danlin No.1’, ‘Danlin No.2’ and CK, with ‘Danlin No.2’ having the largest ear length and ear width, which were 12.54 cm and 7.87 cm respectively. ‘Danlin No.1’ and ‘Danlin No.2’ had no prickle cluster, and the average number of fruit was between 98 and 101, which was significantly different from CK.
