| 摘要: |
| 在陕西杨凌测定了引种的14个树莓品种的生活力、抗病性和繁殖特性。结果表明，生活力强的品种有Heiltage，Summit，Willameppe，Royalty，Kopata和Triplecrown；生活力差的品种有Ruby，Goldensummit，Chiliwack和Meeker。2种最常见的树莓病害是白粉病和茎腐病，红莓和黄莓对这2种病害的抗性较差，而黑莓抗病性强；抗病性较强的品种有Heiltage，Willameppe，Royalty，Boysen，Kopata和Triplecrown，抗病性差的为Chiliwack，Ruby，Summit和Goldensummit。根蘖繁殖技术对Heiltage，Willameppe和Fallgold繁殖效果最好，而Heiltage，Royalty和Triplecrown采用基生枝繁殖技术能获得较好的繁殖效果；使用水平压条技术繁殖效果好的品种有Fallgold，Boysen，Kopata和Triplecrown，而先端压条繁殖技术对Heiltage，Fallgold，Royalty，Kopata和Triplecrown的繁殖效果较好；繁殖力强的品种有Heiltage，Willameppe，Fallgold，Royalty，Boysen，Kopata和Triplecrown。 |

| Abstract: |
| 14 varieties of raspberry introduced to Yangling in Shaanxi province were studied.The results are as follows.Such varieties as Heiltage,Summit,Willameppe,Royalty,Kopata and Triplecrown were more vigorous than Goldensummit,Chiliwack and Meeker.Powdery mildew and diplodinaparasitica were the two dominating diseases that damaged raspberry and red and yellow varieties were prone to infection but black varieties had stronger resistance.Heiltage,Mekker,Willameppe,Royalty,Boysen,Kopata and Triplecrown were most disease resistant while Chiliwack,Ruby,Summit and Goldensummit were the least.The best effect of propagation was achieved by root shoots on Heiltage,Willameppe and Fallgold,by basic growing shoots on Heiltage,Royalty and Triplecrown,by level layering on Fallgold,Boysen,Kopata and Triplecrown,by tip layering on Heiltage,Fallgold,Royalty,Kopata and Triplecrown.Such as Heiltage,Willameppe,Fallgold,Royalty,Boysen,Kopata and Triplecrown have stronger progenitive abilitys.Therefore,Heiltage,Willameppe,Royalty,Kopata and Triplecrown could be the best options to plant in Yangling area in Shaanxi province. |
