Abstract

The method for breeding special hybrid rootstocks for the prevention and treatment of facility watermelon wilt disclosed by the present invention is to select local long gourd varieties in Zhejiang, separate and purify them through at least three generations of self-crossing, identify and screen out the plants that grow steadily under low temperature and low light conditions, and have strong low temperature resistance The inbred line CH-1 was used as the female parent, and the inbred line YH-6 with strong low temperature resistance, drought tolerance and heat resistance was identified and screened as the male parent. A first-generation hybrid was prepared and named "Huluzhen No. 1". The hybrid rootstock selected by the method of the present invention meets the breeding objective, is highly resistant to watermelon wilt, has good grafting affinity with watermelon, and has strong symbiotic affinity, and is suitable for continuous cropping watermelon grafting and cultivation in the south with low temperature and rain in the early stage and high temperature in the later stage, and under facility cultivation conditions Good moisture and heat resistance, stable growth under low temperature and weak light, easy to set fruit, can effectively prevent and control watermelon wilt, increase watermelon production and improve quality.

Description

technical field

[0001] The invention relates to a method for selecting rootstock varieties for grafting watermelons in facilities. Background technique

[0002] Watermelon Fusarium wilt is a worldwide devastating disease, which can lead to a reduction in watermelon production in mild cases, or wipe out the entire field in severe cases. The disease is particularly serious in watermelon cropping fields, which has seriously restricted the sustainable production of watermelon. At present, the methods for preventing and controlling watermelon wilt mainly include the following: 1. Crop rotation and stubble change. This is the simplest, most economical and effective method, but due to the limitation of land area and the limitation of protected cultivation, it is difficult to realize reasonable crop rotation for many years; 2. Chemical control. Using a variety of broad-spectrum fungicides, such as carbendazim, chlorothalonil, thiophanate-methyl, etc., som...
