摘要
为筛选出晚疫病抗性强、产量高、适宜于大面积推广种植的马铃薯品种和优质的亲本材料,研究以‘天薯10号’为对照,对23份国内育成的马铃薯品种的晚疫病抗性、产量进行评价。结果表明,‘农天1号’、‘天薯12号’、‘天薯10号’(CK)、‘陇薯10号’、‘陇薯13号’、‘青薯9号’、‘陇薯11号’和‘陇薯12号’8个品种表现为植株高抗(HR)晚疫病,杂交育种中可作为抗晚疫病品种选育的亲本材料;‘庄薯3号’、‘云薯505’、‘农天2号’、‘陇薯7号’、‘天薯9号’、‘云薯205’、‘天薯11号’、‘云薯303’、‘陇薯6号’、‘云薯807’、‘云薯501’、‘青06-26-7’和‘云薯202’13个品种表现为中抗(MR);其余3个品种‘青薯2号’、‘下寨65’和‘脱毒175’表现为中感(MS)。‘青薯9号’、‘陇薯7号’、‘庄薯3号’、‘农天2号’、‘天薯11号’、‘陇薯13号’、‘云薯505’、‘云薯807’和‘农天1号’9个品种较对照‘天薯10号’增产。综合晚疫病抗性和产量筛选出‘青薯9号’、‘庄薯3号’、‘陇薯13号’、‘陇薯7号’、‘天薯11号’和‘农天2号’6个抗晚疫病性能强和丰产性较好的品种,可在甘肃省天水及周边地区大面积示范种植。
The yield and resistance of 23 potato varieties were evaluated using 'Tianshu 10' as a control in order to screen the large scale cultivated potato varieties and potato breeding material with the strong resistance, high yield and adaptability to late blight. Eight varieties('Nongtian 1', 'Tianshu 12', 'Tianshu 10', 'Longshu 10', 'Longshu 13', 'Qingshu 9','Longshu 11' and 'Longshu 12') were high resistant(HR) to late blight, which would be used as parents of resistance to late blight in cross breeding. Thirteen varieties('Zhuangshu 3', 'Yunshu 505', 'Nongtian 2', 'Longshu 7', 'Tianshu 9', 'Yunshu205', 'Tianshu 11', 'Yunshu 303', 'Longshu 6', 'Yunshu 807', 'Yunshu 501', 'Qing 06-26-7' and 'Yunshu 202') were moderately resistant(MR) and 'Qingshu 2', 'Xiazhai 65' and 'Tuodu 175' were moderately susceptible(MS)to late blight.The yields of nine varieties('Qingshu 9', 'Longshu 7', 'Zhuangshu 3', 'Nongtian 2', 'Tianshu 11', 'Longshu 13', 'Yunshu 505','Yunshu 807' and 'Nongtian 1') were higher than that of 'Tianshu 10'(CK). Based on both disease resistance and yields of tested varieties, six varieties('Qingshu 9', 'Zhuangshu 3', 'Longshu 13', 'Longshu 7', 'Tianshu 11' and 'Nongtian 2') with strong resistance to late blight and high yields were selected, which could be planted on large area in Tianshui of Gansu Province and surrounding areas.
