摘要: 对桃( Prunus persica L. ) 的282~491份品种资源果实的平均单果质量、核质量、可溶性固形物、可溶性糖、可滴定酸、维生素C、带皮硬度和去皮硬度等8项指标进行研究和统计分析, 提出我国桃种质资源评价系统中这些性状的数值分级指标和参照品种, 为我国桃种质资源描述系统数量化、规范化的建立奠定基础。

Abstract: We try to establish a new peach descrip tor system based on the statistics analysis, international Peach Descriptor from IBPGR in 1984, and Chinese peach descriptor in 1990. Fruit quantitative characters of 282 - 491 peach cultivars were investigated atNational Peach Genetic Collection in Zhengzhou
in China from 1986 - 2002. Those characters includes average fruit mass, stone mass, soluble solid content, soluble sugar content, soluble acid content, vitamin C, firmnesswith shin and firmnesswithout skin.Grade index and reference cultivarswere given by statistical data for peach descrip tors. These grade indexes were recorded on 1 - 5 scale. In generally, two reference cultivars for each grade were given, one USA cultivar, another Chinese cultivar. We try to use these as the reference cultivars, which are planted or used by
breeders widely in China.
