Method for domesticating and cultivating high-quality rootstock seedlings by utilizing wild eggplant seeds

Abstract

The invention relates to a breeding method for plant seedlings, in particular to a method for domesticating and cultivating high-quality rootstock seedlings by utilizing wild eggplant seeds. The method specifically comprises the following steps of collecting the wild eggplant seeds as seed sources, and cultivating first-generation rootstock seedlings by virtue of technical measures of performing after-ripening treatment on wild fruits, collecting seeds, mixing fine sand and the seeds, rubbing the seeds until seed coats of the seeds are thinned, impregnating the seeds in warm water for many times, continuing impregnating the seeds in cold water to stimulate the germination of the seeds by the cross use of cold and heat, accelerating the germination and the like; screening advantageous plants from the first-generation seedlings, transplanting the advantageous plants into a field, managing the transplanted plants until the plants are fruited by using a conventional method, screening advantageous plants from eggplant plants, and picking 80 to 90 percent matured and full fruits which are free of pest and disease damage as second-generation seed sources; cultivating the high-quality rootstock seedlings by using the second-generation seed sources.

Description

technical field

[0001] The invention relates to a method for breeding plant seedlings, in particular to a method for domesticating and cultivating excellent rootstock seedlings by using wild eggplant seeds. Background technique

[0002] Solanaceae plants, especially tomatoes and eggplants, are often affected by soil-borne diseases such as Verticillium wilt, bacterial wilt, root-knot filariasis during production and cultivation, resulting in reduced yield or even no harvest. In order to prevent and control these diseases, In the process of production management, too many pesticides are often used, which not only increases the production cost, but also greatly reduces the quality of the finished product. At present, in order to prevent these diseases, the most effective measure is to graft tomato or eggplant scions to rootstocks that can prevent and control diseases and have strong stress resistance, which can not only effectively improve the disease resistance of tomatoes and...
