2019—2020年中晚熟华北组国家马铃薯品种区域试验

为更好适应国内春作马铃薯生产发展的需求,选育适宜华北地区种植的马铃薯新品种,2019—2020年在内蒙古乌兰察布市进行国家马铃薯品种区域试验。结果表明,8个参试品种中,‘YL1106-67’产量最高,产量54810 kg/hm²;‘晋12-13-9’产量47760 kg/hm²,居第2位;‘中薯928’产量46035 kg/hm²,居第3位;3个品种均较对照‘紫花白’增产,增产率分别为26.32%、10%、6.12%,‘YL1106-67’产量与对照‘紫花白’相比差异极显著;‘晋12-13-9’、‘中薯928’与对照‘紫花白’相比差异不显著。综合考虑认为,‘YL1106-67’和‘中薯928’是非常适宜华北地区种植的马铃薯新品种。

Regional Trials of Mid-Late Maturing Potato Varieties in the North China Group 2019-2020

To better adapt to the development of spring potato production in China, and select new potato varieties suitable for planting in north China, the national potato variety regional trials were carried out in Ulanqab of Inner Mongolia from 2019 to 2020. The results showed that among the 8 tested varieties, ‘YL1106-67’ had the highest yield of 54810 kg/hm², followed by the yield of ‘Jin 12-13-9’ of 47760 kg/hm², and the third was the yield of ‘Zhongshu 928’ of 46035 kg/hm². All the three varieties had higher yield than that of the control ‘Zihuabai’, the yield increase rate was 26.32%, 10% and 6.12%, respectively. The yield of ‘YL1106-67’ was extremely different from that of the control ‘Zihuabai’, and the yield difference between ‘Jin 12-13-9’, ‘Zhongshu 928’ and that of the control was not significant. Therefore, ‘YL1106-67’ and ‘Zhongshu 928’ are new potato varieties suitable for planting in north China.
