番茄核雄性不育系大107单株产量杂种优势与遗传效应研究

Research on Heterosis and Genetic Effect of Yield per Plant of Tomato Genic Male Sterile Line,Lycopersicum esculentum L.—'Da107'

[目的]选育优质高产的后代番茄杂交组合(品种)应用于生产。[方法]用番茄大107作为共同母本,与东圣3号、牛番茄、美丽莎、1439、12、A3配制6个杂交组合的F1代及其相应的亲本材料进行单株产量杂种优势与遗传效应的分析。[结果]可作为单株产量性状杂交育种的番茄亲本有大107、东圣3号;6个组合中组合大107×东圣3号单株产量的特殊配合力效应值最高,达到1.139 1,而且具有较明显的杂种优势。[结论]大107×东圣3号是选育单株产量性状的最优杂交组合。

[Objective] The aim was to breed good quality and high output Solanum lycopersicum descendant hybrid combinations（variety） applies in the production.[Method] This experiment takes the thermo-sensitive male-sterile tomato Da107 as common female parent,and Dongsheng No.3,beef tomato,Meilisha,1439,12,A3 as 6 male parent of hybrid for research on heterosis and genetic effect of yield per plant.[Result] Da107 and Dongsheng No.3 can be used as parents for yield per plant breeding.The special combining ability of Da107 × Dongsheng No.3 was the highest in yield per plant and showed 1.139 1,and its heterosis was very significant.[Conclusion] The hybrid combinations of Da107×Dongsheng No.3 was optimum.
