摘　　要：利用3个具有国外血缘的高产抗病籽用西葫芦品系G-5,G-6,G-11和2个抗病籽用自育自交系10-3,3-2作父本,以自育自交系为母本配置杂交组合,经籽粒产量和抗病性比较鉴定,选育出37-4,11-2,11-4,2-2和19-5这5个品质好、产量高、籽粒商品性好的籽粒用西葫芦种质一代杂交组合,其中,11-2表现籽粒洁白,饱满度好,抗逆性强,适应性广,耐密植、增产潜力大,单株平均产籽可达78.3 g,折合公顷平均产籽量2 550 kg,比对照早青一代增产30.8%。Use of the lines from exotic germplasms and own inbred line with high yield and disease resistance seed purposed summer squash G-5,G-6,G-11,disease resistant seed purposed inbred lines 10-3 and 3-2 as the male parent,breed combination for crossing of own inbred lines as female parent,comparison of seed yield and disease resistance,37-4,11-2,11-4,2-2 and 19-5 five lines with good quality,high seed yield,seed purposed summer squash F1 hybrid were bred.Among them,11-2 has the characteristics of white seed,good seed plumpness,strong resistance,wide adaptability,tolerant to high density,and yield increase potentiality.The mean single plant seed yield is 78.3 g and average seed production about 2 550 kg/hm2.The seed yield increased by 30.8% compared with Zaoqing yidai.
