Drought-resistant Genotypes Selection of Yunnan Potato Resources
-
摘要: 用多年收集和选育、引进的云南马铃薯30个品种,以在宣威推广种植面积较大的宣薯4号为对照品种,在宣威农业技术推广中心马铃薯品种展示园进行抗旱性、丰产性和稳产性评价鉴定,筛选适宜当地种植抗旱、丰产的马铃薯品种和育种材料。结果表明:结合根提拉力和产量作为评价旱作马铃薯抗旱种质资源和筛选马铃薯抗旱品种的主要技术指标,05-290、05-363、S03-3276、夏波蒂、05-287、04-016、05-188、宣薯5号、05-225、丽薯200202均高于对照,表现出显著抗性,是较为抗旱的品种。Abstract: Thirty various potato strains were collected and breeded in the laboratory for many years.Control was Xuanshu 4 which was larger production in Xuanwei.In Agricultural Center of Xuanwei potato varieties,drought-resistance,high yield and stability of potato genotypes were evaluated.At last,appropriate local potato varieties were selected,which were drought-resistant and high yield.Results showed that taking root pulling force and yield as main technical parameters,drought-resistance of 05-290,05-363,S03-3276,Shepody,05-287,04-016,05-188,Xuanshu 5,05-225 and Lishu 200202 were higher than that of control,they were drought-resistance varieties.
