摘　　要：以从日本引进的一个印度南瓜类型(代号12)材料中选出的稳定自交系12-97-55为母本,以从台湾引进的一个印度南瓜类型(代号121)材料中选出的稳定自交系T98-6-3-9为父本配制而成早熟一代杂种永安2号.该品种叶面绿色无花斑,瓜型高扁圆形,瓜皮色为绿白相间的小花斑,单瓜重1.5～2.2kg,比对照早熟30d左右,总产量高出25%.该品种营养品质好,对糖尿病有防治作用的铬元素(Cr3+)含量是对照品种的近7倍.Yongan No 2', an new and early-maturing pumpkin Fl hybrid was bred by college of horti-culture,northwest sci-tech university of agriculture and forestry in 2000,with crossing Cucubita maxim D. inbred line 12-97-55 as female parent with early-maturing C.maxim D. inbred 1ine T98-6-3-9 as male parent.It has vigorous plant,and high-oblate fruits with green-white skin.Its yield is about32.46t/hm2 and is 21.7% higher than that of 'xiao mo pan(CK)'.The new pumpkins have high nutritive matter .The Cr3+ is 6.5 times higher than that of 'xiao mo pan(CK)'.It has been extended to Shaanxi,Gansu,Hebei etc.
