摘　　要：为筛选出适宜龙井市种植的优质、高产马铃薯新品种,于2018年引进了6个马铃薯品种进行比较筛选试验,从物候期、植株形态特征、田间性状、块茎性状及生理缺陷、主要病害、产量等方面进行调查分析。结果表明,延薯10号和延薯12号生育期较短、丰产性较好、商品薯率较高,二次生长率和裂薯率也比对照低,均适合进行大面积种植。龙薯11号生育期较长,商品薯率也较低,二次生长率和裂薯率相对其他品种也稍高,但是产量位居第三位,较CK1有明显的提高,与CK2产量也相差不多,可作为替补品种在龙井推广种植。其余品种产量低,综合性状差,予以淘汰。In order to select new potato varieties with high quality and high yield suitable for planting in Longjing city, six potato varieties were introduced in 2018 for comparative screening test, and investigation and analysis were carried out from the aspects of phenology, plant morphological characteristics, field traits, tuber traits and physiological defects, main diseases and yield. The results showed that Yanshu 10 and Yanshu 12 had shorter growth period,better fertility, higher commercial potato rate, lower secondary growth rate and split potato rate than the control group. Longshu 11 has a longer growth period, lower commercial tuber rate, slightly higher secondary growth rate and split tuber rate than other varieties, but its yield ranks the third, which is significantly higher than CK1 and similar to that of CK2. Therefore, it can be used as a substitute variety to promote planting in Longjing. Other varieties with low yield and poor comprehensive characters were eliminated.
