摘要
本研究对我国１１０个山楂种和品种进行了染色体数目观察和农艺、品质、加工、贮藏、矮化等项性状鉴定，获得鉴定评价数据１３２０个，输入到国家种质资源数据库，鉴定筛选出大果型、高糖、高Ｖｃ、极耐贮、优异制汁、矮化、多倍体等２１份稀有珍贵的优异山楂种质。
With the steady growth of economy in China, scientific research on Crataegus plants has increased in recent years, but comprehensive and systematic identification and evaluation of Crataegus resources is still lacking. In an effort to further develop and exploit Crataegus resources in China and to promote international exchange of information in this connection, between 1986and 1990, an investigation was launched, in which 110 Crataegus species and varieties were identified and evaluated for their horticultural traits, fruit and processing quality, storage property,chromosome characters and dwarding effect, and 1, 320 data items were obtained and fed into the nation's germplasm bank for use in germplasm resource research and exploitation, in breeding and in exchange of information. In the course of the study, 21 superior germplasm types were screened out, including 2 big fruit types, 2 high sugar content types, 2 high Vc content types,2 extremely storage stable types, 2 types excellent for juice-making, 10 polyploids and 2 dwarfed types.
