摘要

‘南中105’是以‘NS51-5’作母本，以‘DY14-4-13’作父本，通过有性杂交、选育得到的中晚熟鲜食马铃薯新品种。生育期约92 d，株高85 cm，株型半直立，分枝中等；块茎长形，淡黄皮淡黄肉，薯皮光滑，芽眼浅；平均单株结薯数9.7个，块茎整齐，匍匐茎短，商品薯率63.7%。干物质含量20.9%，淀粉含量15.77 g/100 g，蛋白质含量2.84 g/100 g，维生素C含量98.4 mg/kg，还原糖含量0.14 g/100 g。2014—2015年品种比较试验中‘南中105’产量1 849 kg/667m²，比对照‘鄂马铃薯5号’增产6.0%，比对照‘米拉’减产1.1%。田间鉴定，对晚疫病抗性高于对照品种‘鄂马铃薯5号’及‘米拉’，轻感花叶病和卷叶病。适宜湖北省保康、谷城、宜昌、恩施等西部、北部高山、二高山地区的春作区种植。

Abstract

'Nanzhong 105' is a new mid-late maturing table potato variety developed through sexual hybridization and selection, using 'NS51-5' as the female parent and 'DY14-4-13' as the male parent. Its growth period is about 92 days, with a plant height of 85 cm. The plant type is semi-erect, and branching is moderate. Tubers are oblong, with pale yellow skin and pale yellow flesh, smooth skin and shallow eyes. Average number of tubers per plant is 9.7, with uniform tubers, and short stolons. The marketable tuber percentage is 63.7%. The content of dry matter is 20.9%, starch 15.77 g/100 g, protein 2.84 g/100 g, vitamin C 98.4 mg/kg, and reducing sugar 0.14 g/100 g. In the 2014-2015 variety comparison trial, the yield of 'Nanzhong 105' was 1 849 kg/667m², representing a 6.0% increase compared to the control variety 'Emalingshu 5' and a 1.1% decrease compared to the control variety 'Mira'. Field trials indicate that its resistance to late blight is higher than those of the control varieties 'Emalingshu 5' and 'Mira', but it is slightly susceptible to mosaic disease and leafroll disease. It is suitable for planting in the spring cropping areas of high mountains and sub-high mountains in western and northern Hubei Province, such as Baokang, Gucheng, Yichang, and Enshi.
