摘要
为筛选出适宜万州区种植的优质高产抗逆性强的马铃薯品种,从四川、重庆、湖北恩施州等地的农科院引进10个马铃薯新品种(系)进行试验,对品种物候期、生物性状、晚疫病抗性、块茎结薯习性及产量等进行调查分析。结果表明,鄂薯14号、鄂薯16号的丰产性较好且抗病性强尤其是晚疫病抗性强,可进行大面积示范;丽薯6号、合23M-2的产量较高,但中度感晚疫病,推广应用时要注重晚疫病防控;渝薯3号和渝薯6号产量、抗病性等表现较优但有空心等生理缺陷,可续试,其余品种产量低适应性差予以淘汰。
In order to screening out high quality, high yield and strong resistance potato varieties for planting in Wanzhou, Chongqing, ten potato varieties(lines) were introduced from Sichuan academy of agricultural sciences, Chongqing academy of agricultural sciences and Enshi academy of agricultural sciences et al., the growth period, plant character, late blight resistance, tuber habit and potato yield were surveyed. The results showed that the potato yield and disease resistance of Eshu No.14 and Eshu No.16 were good, especially for late blight, which could be large area planting. The yield of LishuNo.16 and He 23M-2 were higher but moderate infection with late blight, should be pay attention to the prevention and control of late blight when promoting application. YushuNo.3 and YushuNo.6 have a good yielding but potato got hollow phenomenon that maybe test continue. However, the other varieties(lines) have low yield and poor adaptability that could be eliminate.
