Abstract

The present invention discloses a novel isolated culture method for cherry intraspecies and intraspecific hybrid embryo. The novel isolated culture method comprises: hybrid obtaining, a hybrid pretreatment, hybrid sterile material establishment, hybrid embryo subculture, hybrid embryo strong seedling culture, hybrid embryo rooting culture, seedling exercising transplantation, and transplanting into field. According to the present invention, the hybrid embryo isolated culture method is utilized, such that a male parent for new cherry variety breeding and having excellent characteristics and a female parent for new cherry variety breeding and having excellent characteristics can be effectively screened, it is ensured that the bred filial generation has the same excellent characteristics of the male parent and the female parent, and the bred hybridization variety has targeting property and universality; and a large number of cherry seedlings can be rapidly bred in a low cost manner, and a production period is short, such that economic benefits are good, and good market prospects are provided.

Description

technical field

[0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to a method for in vitro culture of novel cherry intraspecific and interspecific hybrid embryos. Background technique

[0002] Cherries belong to the deciduous trees of the genus Prunus in the Rosaceae family. Classification according to fruit structure Cherry fruit belongs to drupe fruit. Due to the short development period and early maturity period of cherry fruit, the fruit is listed in the off-season of the fresh fruit market. The fruit is beautiful in color, rich in nutrition, and suitable for fresh food and processing. It is known as a treasure among fruits. There are more than one hundred species of Prunus genus, and the main economically cultivated fruit trees are Chinese cherry, European sweet cherry and European sour cherry. Chinese cherry is native to my country and has many varieties. It has a long history of cultivation and a certain cultivation a...
