　　影响马铃薯引种成功与否的因素有很多，如纬度、海拔、气候条件和品种生育期等。本试验选取当地主栽马铃薯品种‘龙引薯1号’和‘克新13号’，分别来源于不同纬度地区呼玛县、嫩江县和林甸县的种薯，引种到林甸县，测定生长期间的株高和茎粗、收获后的块茎产量和大中薯率，淀粉含量，提取淀粉产量并测定淀粉黏度和糊化温度，以分析比较不同纬度引种对马铃薯植物学性状、产量及品质的影响。结果表明，两个品种均表现为来源于高纬度地区的种薯长出的马铃薯植株高大、茎秆粗壮，产量高、大中薯率高，淀粉产量也高，但淀粉提取率、淀粉黏度及糊化温度变化规律不明显。

Many factors, such as latitude, altitude, climatic conditions and the variety maturity, could influence whether or not potato introduction is successful. In this research, the seed potatoes of the varieties, 'Longyinshu 1' and 'Kexin 13', which were grown from different latitude areas, Huma County, Nenjiang County and Lindian County, were introduced and planted at the same location, Lindian County. Plant height, stem diameter, tuber yield, large- and medium-sized tuber percentage, tuber starch content and yield, starch viscosity and gelatinization temperature were measured, aiming at understanding the effects of latitude where seed potatoes were grown on potato plant characters, tuber yield and quality. The results showed that for both varieties, potatoes grown from seeds of high latitude performed wel in terms of plant height, stem diameter, tuber yield, large- and medium-sized tuber percentage, and starch yield, but for starch extraction rate, viscosity and gelatinization temperature no significant difference was found.
