摘要
‘中加7’是以‘费乌瑞它’为母本,‘BQ-46’为父本,通过有性杂交选育而成的鲜食马铃薯新品种。2021年通过农业农村部非主要农作物品种登记,登记编号:GPD马铃薯(2021)150003。中熟,生育期85 d左右。株型直立,植株生长势较强,茎、叶绿色,花冠白色,开花繁茂,可自然结实。块茎椭圆形,薯皮黄色,薯肉淡黄色,芽眼平浅,结薯集中。干物质含量21.50%,淀粉含量17.49%,蛋白质含量1.74%,维生素C含量42.50 mg/100 g,还原糖含量0.10%。单株结薯数4~7个,平均单薯重181.05 g,商品薯率83.10%。在2020年生产试验中,‘中加7’平均产量3026 kg/667m^(2),较对照‘费乌瑞它’(2390 kg/667m^(2))增产26.61%。对马铃薯X病毒(Potato virus X,PVX)病表现感病,中抗马铃薯Y病毒(Potato virus Y,PVY)病,中感晚疫病。适宜在北方一作区内蒙古自治区、河北省、陕西省春季种植,中原二作区山东省春季种植,南方冬作区广西壮族自治区冬季种植。
