炸条专用马铃薯品种克新17号的选育研究 及马铃薯品质育种等问题的探讨

根据中国马铃薯产业发展的需要,黑龙江省农业科学院马铃薯研究所1997年开始了马铃薯炸条专用品种选育研究,利用高产、商品薯率高的亲本F81109与还原糖含量低、干物质含量高、炸片品质好的品种B5141-6杂交,经多年选育鉴定育成白皮白肉炸条专用品种克新17号,于2005年3月经黑龙江省农作物品种审定委员会审定推广。该品种干物质含量23.37%左右,Vc含量20.43毫克/100克鲜薯,还原糖0.213%,食味好,抗病毒退化能力强、高产、综合性状优良,炸条产品色泽好,同时本文对中国培育炸条品种的亲本选配及杂种群体处理方法作了探讨。

Breeding of Potato Variety "Kexin No.17" Specially for French Fries and Problems on Potato Breeding for Quality and Others

This paper introduces the breeding of new potato cultivar "Kexin No.17"which is special for French Fries. In 1997 by hybridizing between F81109, a high yield and high commercial tuber ratio cultivar, and B5141-6, an American cultivar which is characterized by its high matter content, lower reducing sugar content and good quality for French fries. By many years of selection, Kexing No17 was bred with white skin and the same color flesh. Kexing No17 was examined and approved as extension cultivar by Heilongjiang Crop Cultivar Examination and Approval in 2005. KexingNo.17 is a good French fries and high yield cultivar with resistant to viruses , and its dry matter content is about 23.37%, Vc 20.43mg/100g fresh tuber, Reducing sugar 0.213%. At the same time, the issues of how we select the parents and treat the progeny population for potato quality breeding are also discussed in the paper.
