桃种质资源冻害情况调查报告

Investigation of Cold Damage to Peach Cultivars in Germplasm Plot

对北京市农林科学院林业果树所国家果树种质桃质资源圃内的380份桃种质资源进行了冻害调查。结果表明:桃抗寒力因品种不同而异,抗寒能力较强的品种(系)有西伯利亚C、GF677、珲春桃、中宁3号、曲枝山桃、五宝桃、白花山桃;最弱的是寿红、安康毛桃9、6-3-54、Mafim、霞晖7号、昆旺毛桃、红不软、南山贡桃、奉化玉露、南山甜桃1号、南山甜桃6号、莱山蜜、满城雪桃、迟园蜜、早魁蜜、早硕蜜、中华寿桃等,摸清了桃种质间抗寒力的差异,从中筛选出抗寒品种(品系),为桃的北方产区选择品种以及抗寒育种亲本选择提供科学的依据。

The cold damage of 380 peach germplasm resources were indagated within national genetic resource garden of Pomology of Institute of Forestry and Pomology,Beijing Academy of Agricultural and Forestry Sciences.The results showed that the cultivars with strongest freezing resistance ability were Siberian C,GF677,Hunchuntao,Zhongning 3,Prunus davidiana（Carr.） Franch（tortuous branch）,Wubaotao and Prunus davidiana（Carr.） Franch（white flower）.The weaker ones were Shouhong,Ankang-maotao,96-3-54,Mafim,Xiahui7,Kunwangmaotao,Hongburuan,Nanshan-gongtao,Fenghuayulu,Nanshantiantao 1,Nanshantiantao 6,Laishanmi,Mancheng-xuetao,Chiyuanmi,Zaokuimi,Zaoshuomi,Zhonghuashoutao.Knowing the differences of cold hardiness among different Peach germplasms so as to select cold resistant varieties and provide scientific evidence for selecting varieties for the north areas and peach breeding.
