摘　　要：中早熟马铃薯在日喀则市马铃薯产业发展中的作用日益凸显。以日喀则市的主栽品种艾玛1号为对照,通过观察和记录中早熟马铃薯的生物学性状和物候期,并测定淀粉等指标含量,筛选出适合本地区种植的中早熟马铃薯品种。结果表明,SD2的生育期最短,为103 d。SD2和冀张12的产量略低于对照,但无显著差异;其余6个品种(系)与对照品种在产量上存在显著差异。在商品薯率方面,除永丰3号、LK99和V7低于对照外,其余品种(系)均高于对照。在淀粉含量方面,SD1、SD2和永丰3号高于对照,其余品种(系)低于对照。综合筛选结果显示,SD2表现最佳,适宜作为中早熟品种在当地推广;希森6号和陇薯20适合在马铃薯主产区结合大田实际表现进行种植;冀张12可以在本地区马铃薯种植区域进行示范种植;SD1和永丰3号可以作为高淀粉育种的亲本利用。The role of medium-precocious potatoes in the development of potato industry in Shigatse City is increasingly prominent.This experiment is based on the potato main variety in Shigatse City,Emma No.1,as a control group.By observing the biological characteristics and maturation periods of early precocious potatoes,the content of starch is determined to scree the medium-mature potato varieties suitable for planting in the region.The results show that SD2 has the shortest maturation period at 103 days.The yield of SD2,Jizhang 12 is slightly lower than that of the control group,but not significantly different statistically.The remaining 6 varieties(strain)are significantly different from the control group in terms of yield performance.In terms of product potato ratio,except Yongfeng No.3,LK99,and V7 lower than the control group,the remaining varieties(strain)are higher than the control.In terms of starch content,SD1,SD2 and Yongfeng 3 are higher than the control group,and the remaining varieties(strain)are lower than the control group.Comprehensive screening results showed that SD2 performs best among these tested varieties and is suitable for local promotion as a medium-early maturity variety.Hersen 6 and Longshu 20 should be planted in the actual performance of the potato production area.Jizhang 12 can be used for demonstration planting in potato growing areas in this region.SD1 and Yongfeng 3 can be used as a high starch breeding parent.
