Abstract: A new peach(Prunus persica)line named 'Beilun 02-1' was discovered at a peach orchard in Beilun,Ningbo,Zhejiang Province in 2002.Based on four-year observation,'Beilun 02-1' was found ripe early with large fruit.In order to identify this line,this study was carried out to compare its phenological phase and fruit traits with reference cultivar 'Hujingmilu'.AFLP and SSR markers were also used to reveal its genetic identity in comparison with local peach cultivars 'Zaohongbaoshi','Datuanmilu','Hujingmilu','Yulu','Late Yulu' and 'Ohdama Hakuhoh'.It was found that fruits of 'Beilun 02-1' ripened around June 20 th,and had average fruit weight of 196 g,with red color on the tip and high fruit quality.Based on three SSR markers,'Beilun 02-1' displayed different from some local cultivars such as 'Hujingmilu','Datuanmilu' and 'Yulu'.SSR marker pchcms5,located on linkage group 6,was able to be used to distinguish 'Beilun02-1' from 'Hujingmilu'.Three out of twenty-four AFLP primer pairs tested also told difference between 'Beilun02-1' and 'Hujingmilu'.We concluded that 'Beilun02-1' was a tentative new line different from other local cultivars.

Key words: 'Beilun 02-1', peach(Prunus persica), a new line, genetic identity, SSR, AFLP
