Application of New Tomato Male Sterility System in Hybrid Seed Production —— Wikipedia Information Analysis and Testing Encyclopedia

At present, tomato hybrid seed production adopts artificial emasculation pollination, which has the risk of high seed production cost and difficult guarantee of hybrid purity. Using male sterile line as female parent to produce hybrid seeds can reduce the number of artificial emasculation, thus reducing the cost, improving the purity of seeds and avoiding artificial emasculation. ...

Breeding technology of tomato improved varieties-agricultural planting network

There are two main methods to produce tomato hybrids: artificial emasculation and artificial mating, and male sterile seed production. A. In tomato hybrid seeds produced by artificial emasculation and artificial mating, when parents are paired, the genetic characters of their reciprocal crosses are the same. But when using seeds, it is beneficial to seed production. ...

Male sterile seed production system mainly has the following advantages: 1, male sterile line is caused by recessive mutation of nuclear gene, and theoretically any male fertile inbred line can be used as male restorer line, so the selection of male parent is not limited during hybridization; 2. Male sterile lines are produced by the following methods. ...
