Main breeding methods for bananas

All the edible bananas in the world have evolved from the two wild species of bananas: Stereophaga and S. sinica. In its evolving process, in addition to natural selection, artificial breeding and selection play an important role in the evolution of bananas. This means that when bananas are selected by nature, they only choose the type that adapts to the tropical and subtropical ecological conditions, while the artificial selection is the choice of the economic traits of bananas and the selection of new banana varieties that meet the economic requirements of humans. However, the excellent properties of bananas are not eternal, but they also appear to be degraded in production. Especially in the tropical and subtropical banana growing areas of South China, where cold, wind, drought, locusts, and pests and diseases frequently occur, the development of the banana industry Affected greatly. Therefore, how to breed new varieties and types and how to purify and rejuvenate the original fine varieties is one of the challenges that banana professionals are eager to solve.
The breeding methods for bananas include introduction, bud selection, sexual crossbreeding, distant crossbreeding, radiation breeding, multiple breeding and other methods. Taking into account the practicality of banana production, the basic techniques for introduction and selection of bananas for bananas are now described as follows:
Banana introduction Although China's banana resources are very rich, due to the uneven distribution of banana varieties and varieties and the diversity of banana production and consumption, it is very necessary to introduce new varieties and types from home and abroad.
In fact, introduction of bananas is a method that requires the shortest time, the simplest method, and the most significant effect in the banana breeding pathway. It is precisely because of this that over the years, banana growing regions such as Guangdong, Guangxi, and Fujian have continuously introduced new varieties and types of bananas from home and abroad. The introduction of species between domestic provinces has become more frequent, and more varieties and types have been introduced. Introduced greatly enriched the local banana germplasm resources, and some varieties such as Williams and Vietnam 63-1 also played a large role in local production. The key to the success of banana introduction is.
