After several years of screening, Zhengzhou Vegetable Research Institute has used the negative ion introduction technology to breed a new tomato line with a higher value of the product. At present, this tomato line has a stable performance in production and is used as a new material in tomato breeding.
The application of negative iontophoresis technology in tomato breeding is a cooperative project between the tomato laboratory of the institute and the ion beam mutation breeding and biotechnology laboratory of Zhengzhou University. Through the use of negative ion introduction to induce mutation of new varieties, it has been widely used in wheat and other crops, but it is the first time in the country for the application of vegetable breeding.
On July 6, the reporter saw at the Experimental Research Center of the Vegetable Research Institute of Zhengzhou City that the leaves of this tomato were completely shrunken, and the leaves were fine and broken, with obvious keratinization. The fruit was highly rounded and the top was prominent. The appearance was like nectarine. The size is also similar to that of nectarine, which can be used to cultivate fruit-type tomatoes and improve the fruit shape index of existing varieties to increase the value of the commodity.
According to the researcher of the Tomato Research Laboratory of the Vegetable Research Institute of Zhengzhou City, according to the researcher Fang Fangqing, according to the tomato leaf area and fruit setting ability, the photosynthetic efficiency of the plant is 6 to 8 times higher than that of ordinary tomatoes. At present, researchers are conducting drought resistance tests on this new line of tomato plants. If their drought tolerance is further confirmed, they will develop new drought-tolerant tomato varieties through breeding and other means.
