The invention provides a fast, simple and effective method for identifying resistance to tomato yellow leaf curl virus, belonging to the field of plant protection. The tomato yellow leaf curl virus is a virus spread by bemisa babaci, the multi-sampling bemisa babaci inoculation identification method is applied to the traditional virus resistance identification; however, as affected by the bemisa babaci (such as inoculation quantity, virus-carrying rate and chow characteristic of the bemisa babaci) the bemisa babaci inoculation identification method is very difficult to provide uniform inoculation pressure and at the same time is interfered by other virus spread by the bemisa babaci, which leads to poor accuracy and repeatability of the identification result. However, the toothpick inoculation method well solves these problems, uses the constructed infective cloning, inoculates the tomato yellow leaf curl virus by puncturing the phloem of a tomato by a toothpick and identifies the resistance of the tomato material to the tomato yellow leaf curl virus. The method of the invention has the characteristics of no need to raise the bemisa babaci, simple operation, high efficiency, good repeatability, good controllability, accurate identification result and capability of providing relatively uniform inoculation pressure, thus being a simple and effective inoculation identification method.
