马铃薯品种泉云3号在南安市的适应性评价

Adaptability Evaluation of the Potato Variety Quanyun No.3 in Nan′an City

为南安市马铃薯产业发展品种选择提供参考,以紫花851为对照,在南安市对泉云3号开展了冬作适应性试验。结果表明:泉云3号单株薯重631.0 g,优于对照(539.0 g),产量37860.0 kg·hm^(-2),比对照增产11.71%;生育中后期茎叶衰老变缓、光合物质分配能力强于对照,薯块膨大迅速,是其丰产的主要原因;田间抗性表现强于对照,抗晚疫病、高抗早疫病,卷叶和重花叶病毒病的发病率均低于对照;块茎品质适于膨化薯片加工(对照适于蒸食食品),投入产出比为1∶2.05(对照为1∶1.63),比对照新增效益20562.00元·hm^(-2)。

In order to provide reference for the variety selection of potato industrial development in Nan′an City,the winter cropping adaptability test of Quanyun No.3 was carried out in Nan′an City with Zihua 851 as the control group.The results showed that the tuber weight per plant of Quanyun No'3 was 631.0 g,which was better than that of the control group(539.0 g),and the yield of Quanyun No.3 was 37860.0 kg·hm^(-2),which was 11.71%higher than that of the control group.The main reasons for the high yield of tubers were the slow senescence of stems and leaves in the middle and late growth period,the stronger ability of photosynthetic material distribution and the rapid expansion of tubers.The resistance in field of Quanyun No.3 was stronger than that of the control group,being resistant to late blight,and highly resistant to early blight,and the incidence rate of leaf roll virus and severe mosaic virus were both lower than that of the control group.The tuber quality was suitable for the processing of puffed potato chips(the control group was suitable for the steamed food),the input-output ratio was 1∶2.05(the control group was 1∶1.63),and the new efficacy was 20562.00元·hm^(-2) compared with that of the control group.
