摘　　要：为筛选适宜湛江地区种植的马铃薯新品种,对引进的9个华薯系列新品种进行适应性、丰产性试验,以"洋人洋"品种为对照,对9个品种进行了物候期及植株形态观察、各品种田间性状及块茎性状评价和产量测定。结果表明:9个品种均为中早熟品种,"华薯1号"和"华薯2号"综合表现优良,具有生长势强、产量高等特点,折合产量分别为38019kg/hm^2和34850.7kg/hm^2,较对照"洋人洋"分别增产21.93%和11.76%,可在湛江地区推广;"RJB"品种为紫皮纹状紫肉品种,综合性状表现良好,可作为彩色马铃薯品种在湛江地区进行推广;其他品种需进一步试验,确定是否在湛江地区有推广价值。We introduced nine new varieties of "Hua shu" series potato in Zhanjiang,and the "Yang ren yang" was used as control.The phenological period and plant morphology were observed;the field and tuber traits were evaluated;and the yields of the nine cultivars was determined.The results showed that all nine varieties were Middle-early maturing varieties,and the comprehensive performance of "Hua shu No.1" and "Hua shu No.2" were excellent,with strong growth potential and high yield.The combined yields were 38 019 kg/hm^2 and 34 850.7 kg/hm^2,respectively,which were 21.93% and 11.76% higher than the control.Hence,"Hua shu No.1" and "Hua shu No.2"can be extended in Zhanjiang."RJB" is a purple skin and purple meat variety with good comprehensive performance.It can be extended also as a color potato variety in Zhanjiang.Other varieties need to be further tested to determine whether they are worth popularizing.
