摘要
克新37是以东农303为母本,以克新16号为父本进行有性杂交、无性系鉴定筛选育成的鲜食马铃薯新品种。早熟,株型半直立,生育期约66 d(天)。结薯集中,薯块短卵圆形,芽眼中等,黄皮浅黄肉,干物质含量16.0%,淀粉含量10.8%,蛋白质含量1.78%,VC含量351.2 mg·kg^(-1),还原糖含量0.28%。中抗PVX、PVY和晚疫病,单株结薯数5~7个,平均单薯质量212.3 g,商品薯率83.40%~94.31%,每667 m2产量3000 kg左右,适宜在黑龙江省各生态区种植。
‘Kexin 37’is a new fresh po tato variety developed through sexual hybridization and clonal selection,using‘Dongnong 303’as female parent and‘Kexin No.16’as male parent.It exhibits early maturity,with a growth period of about 66 days.The plant type is semi-upright.The tubers are concentrated,short oval-s haped,with moderate bud eyes,yellow skin and light yellow flesh.The dry matter content is 16.0%,starch content is 10.8%,protein content is 1.78%,VC content is 351.2 mg·kg^(-1),and reducing sugar content is 0.28%.It is moderately resistant to PVX,PVY,and late blight.It produces 5-7 tubers per plant,with an average single tuber weight of 212.3 g,and a commercial tuber rate of 83.40%-94.31%.The yield is about 45 t·hm^(-2).It is suitable for planting in various ecological a reas of Heilongjiang Province.
