【摘要】 宁海县马铃薯种植品种以本地品种‘东仓种’为主,因结构单一、种性退化导致马铃薯产量与品质下降。为了筛选适合在宁海县种植的新品种,引进6个马铃薯品种进行比较试验,以‘中薯3号’和本地‘东仓种’作对照,调查不同品种的生育期、块茎性状和经济性状,并测定其产量。结果表明,‘浙薯956’和‘希森6号’商品薯率较高,分别达到83.36%和79.27%,产量较‘中薯3号’分别下降4.60%和16.71%,但较‘东仓种’分别增加60.37%和40.00%,块茎性状等综合表现良好,建议在当地进一步试验示范。更多还原

【Abstract】 The potato varieties grown in Ninghai County are dominated by the local variety ’Dongcangzhong’. Due to few varieties available for farmers choice and deterioration of seed potatoes, the yield and quality of potatoes are declined. In order to select new potato varieties suitable for planting in Ninghai County, six potato varieties were introduced for comparative test using ’Zhongshu 3’ and local variety ’Dongcangzhong’ as controls. The growth duration,tuber characters and economic characters of different varieties were investigated, and their yields were determined. The marketable tuber percentage of ’Zheshu 956’ and ’Xisen 6’ were higher, reaching 83.36% and 79.27%, respectively. The yield of ’Zheshu 956’ and ’Xisen 6’ decreased by 4.60% and 16.71%, respectively, compared with ’Zhongshu 3’, but increased by 60.37% and 40.00%, respectively, compared with ’Dongcangzhong’. The comprehensive performance of tuber characters of these two varieties was good, so it is suggested that these two varieties be further tested and demonstrated in local areas.更多还原
