Method for Seed Production Using Tomato Male Sterile Line

Abstract

The invention relates to the technical field of methods for manufacturing tomato seeds and discloses a method for manufacturing seeds by means of a tomato male sterile line. The method for manufacturing seeds by means of the tomato male sterile line comprises the following steps that 1, tomato hybrid seeds are sown in a cell pan, each cell contains one seedling, and after seedlings emerge, seedlings with purple seedling stems and seedlings with green seedling stems are produced. According to the method for manufacturing seeds by means of the tomato male sterile line, in the process of manufacturing tomato hybrid seeds, the male sterile line and a restoring line are utilized for hybridization to obtain hybrid seeds, no artificial castration is needed, the labor cost of artificial castration is avoided, the situation of labor tension of a pollination peak season is relieved, and the purity of the hybrid seeds obtained through the method for manufacturing seeds by means of the tomato male sterile line is 100%; compared with an existing tomato seed manufacturing method, the purity of manufactured seeds is improved, and genetic resource protection is promoted.

Description

technical field [0001] The invention relates to the technical field of methods for producing tomato seeds, and relates to a method for producing seeds using tomato male sterile lines. Background technique [0002] Tomato is a strictly self-pollinating crop with obvious heterosis. At present, hybrid seeds are mainly used in tomato production. When preparing hybrid seeds, they are manually detasselled and pollinated, which is not only time-consuming and labor-intensive, but also has high seed production costs. In addition, the phenomenon of "false hybrids" often caused by the mixing of self-bred seeds affects hybrid seeds. purity. At present, for tomato varieties, most of the male sterile types that have been discovered and published are nuclear sterile types. There is no maintainer line for this type, and there are common problems such as unstable fertility and difficult maintenance. In the conventional hybrid seed production process, the most labor-intensive process is art...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a method for producing seeds using tomato male sterile lines, which overcomes the deficiencies in the prior art and can effectively solve the problem of existing tomato seed production. In the process, there is a problem that manual emasculation is required. The present invention discloses a method for producing seeds using tomato male sterile lines for the first time, which avoids the labor cost of manual emasculation, alleviates the labor shortage situation during the peak pollination period, and according to the present invention The purity of the hybrid seeds obtained by the method for producing tomato male sterile lines is 100%.
