南瓜新品种永安3号的选育研究

为培育适合保护地栽培的优质红皮色南瓜品种，西北农林科技大学园艺学院采用自交分离、纯化获得自交系，利用自交系选育杂种一代的方法，以从日本引进的一个印度南瓜类型（代号Ps18）材料中选出的稳定自交系Ps18—12．97．55为母本，以从台湾引进的一个印度南瓜类型（代号Js98）材料中选出的稳定自交系Js98-6-3-9-13为父本配制而成早熟一代杂种永安3号。于2007年通过新疆区农作物新品种登记。该品种叶面绿色无花斑，瓜型高扁圆形，瓜皮色为桔红色，单瓜重1．5kg左右，最大可达2．5埏，比对照早熟20-25天，总产量高出26％左右，营养品质明显优于对照品种，适合保护地和夏季气候冷凉地区种植。
