摘　　要：【目的】探明番茄正反交组合间的差异。【方法】采用随机排列,对38个番茄正反交杂交组合F1早熟性状和产量性状进行田间比较试验,并用DPSv7.05统计软件的配对t检验对试验数据进行统计分析。【结果】番茄正、反交组合间首花节位、开花至果实成熟时间的双尾检验概率值分别为0.716,0.907,每序花数、每序果数、单果重和产量的双尾检验概率值分别为0.390,0.087,0.942,0.090。【结论】番茄首花节位、开花到果实成熟时间等早熟性状,以及每序花数、每序果数、单果重和产量等产量性状的正反交组合之间均无显著差异,细胞质效应不明显。【Objective】 The aim was to study the differences between obverse and inverse crosses of tomato.【Method】 The field comparison test of earliness characters and yield characters of 38 obverse and inverse crosses of tomato was conducted by random arrangement,and the experimental data was statistically analyzed by Paired-Samples t test of DPSv7.05.【Result】 P-value of the first flower node and days from flowering to fruit maturity were 0.716 and 0.907 respectively,P-value of flower number per inflorescence,fruit number per inflorescence,single fruit weight,total yield were 0.390,0.087,0.942 and 0.090 respectively.【Conclusion】 There were no significant differences between the couple crosses of earliness character including the first flower node,days from flowering to fruit maturity,and yield component traits including flower number per inflorescence,fruit number per inflorescence,single fruit weight and total yield,and the effects of cytoplasm on these characters were not significant.
