抗病高产籽用西葫芦新品种的选育

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%。

Breeding of Seed Purposed Summer Squash with High Yield and Stronger Resistance

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.
