摘　　要：以12份番茄种质为试材,其具有2类果实大小和3种不同抗性基因,通过检测番茄黄化曲叶病毒病田间抗性和带毒量指标,探索果实大小、抗病基因与田间抗性、带毒量之间的关系。结果显示,在自然传毒情况下,所有番茄材料都能检测到病毒感染。在番茄定植后28 d,小果型番茄M8(I)、M5(I)、M3(I)、M7(I)、M9(I)和M11(HR)带毒量均较低,大果型番茄M6(S)、M10(S)、M4(S)和M2(S)带毒量均较高,且小果型番茄田间发病率明显低于大果型番茄。除了Ty-1/ty-1单基因抗性不受番茄果实大小影响外,携带其他单基因或聚合基因抗性的番茄种质均与果实大小有关。在此节点上,带毒量越高抗性越弱,带毒量越低抗性越强。总体来说,在遭受番茄黄化曲叶病毒侵染时,小果型番茄田间抗性强于大果型番茄。In this study,12 tomato germplasm with 3 different resistance genes and two kinds of fruit sizes were selected as samples to reveal the relationship between fruit size,resistance genes and field resistance and virus concentration of tomato yellow leaf curl virus.The results showed that in the case of natural transmission,virus infection can be detected in all tomato materials.On the 28th day after tomato seedlings were planted,the viral loads of small-fruit tomatoes M8(I),M5(I),M3(I),M7(I),M9(I)and M11(HR)were low,while those of large-fruit tomatoes M6(S),M10(S),M4(S)and M2(S)were high,and the incidence of infection in small-fruit tomatoes was significantly lower than that in large-fruit tomatoes.In addition to Ty-1/ty-1 single gene resistance was not affected by tomato fruit size,tomato germplasm carrying other single gene or polymeric gene resistance was related to fruit size.At this node,the higher the amount of poison,the worse the resistance,and the lower the amount of poison,the stronger the resistance.In general,the field resistance of small fruit tomatoes was higher than that of large fruit tomatoes when infected with tomato yellow leaf curl virus.
