摘　　要：以温敏型核雄性不育系大107为母本,以6个自交系东圣3号、牛番茄、美丽莎、1439、12、A3为父本进行杂交,配制6个番茄新组合,采用酸碱滴定法,对成熟期果实的总酸进行测定,从而对果实总酸估算杂种优势、配合力和遗传力等参数,并进行同亲回归分析。结果表明:6个杂交组合中,2个组合的果实总酸度表现为正向杂交优势,4个组合表现为负向优势,此外,有1个组合表现出超亲优势;果实总酸一般配合力仅为17.18%,特殊配合力高达82.82%,广义遗传力及狭义遗传力分别57.30%和46.68%。而果实总酸的同亲相关系数为-0.0415,没有达到显著水平,仅表现出存在负相关。This experiment took genic male-sterile Da107 as female parent and hybridized it with 6 inbred lines（Dongsheng No.3,Niufanqie,Meilisha,1439,12 and A3）as male parent,and 6 new tomato（Lycopersicon esculentum L.）combinations were compound.The total acid of matured fruit combinations was determined by acid-base titration,so as to estimate heterosis,combination ability and heritability etc.The regression analysis was carried out.The results showed that among the 6 combinations,2 had positive heterosis,4 showed negative heterosis and 1 was over-parent heterosis.The general combining ability and special combining ability of fruit total acid were 17.18% and 82.82%,respectively.The broad-sense heritability and narrow-sense heritability were 57.30%,46.68%,respectively.And the constant parent correlation coefficient was-0.0415,which had not reached the significant level,just expressed as negative correlation.
