Cultivation method of mango virus-free seedlings

Abstract

The invention discloses a cultivation method of mango virus-free seedlings. The method specifically comprises the steps of firstly building a seed-introduction observation orchard, an experimental orchard, a foundation stock field, a female parent orchard and a presenting orchard, selecting original female parent materials to be introduced into the seed-introduction observation orchard, the experimental orchard, the foundation stock field, the female parent orchard and the presenting orchard, continuously spot-checking virus disease infection situations for nursery stocks through the seed-introduction observation orchard, the experimental orchard, the foundation stock field, the female parent orchard and the presenting orchard, and accelerating propagation of the nursery stocks after it isconfirmed that mango seedlings in the female parent orchard and the presenting orchard are not infected by the virus disease. Mass propagation is conducted only after observing the variety features of the nursery stocks at multiple layers, it is guaranteed that the nursery stocks are pure and free of virus, and it is also guaranteed that the quality of the mangoes is excellent and the yield of the mangoes is steadily increased. According to the cultivation method of the mango virus-free seedlings, the industrialization, scale and intensification propagation and production of the high-qualitymango nursery stocks are more promoted.

Description

technical field [0001] The invention belongs to the new technology field of plant seedling propagation, and in particular relates to a method for cultivating virus-free mango seedlings. technical background [0002] Mango is one of the most widely distributed fruit trees in the world. It is native to India and Malaysia. India has the longest cultivation history and the largest output, accounting for 80% of the world's output. Mangoes are grown in Taiwan, Guangdong, Guangxi, Hainan and southern Fujian, and southern, southeastern and southwestern Yunnan. [0003] The climate in Guangdong, Guangxi, and southern Fujian in my country is most suitable for cultivating and multiplying mango seedlings. Guangxi is the province with the highest yield, with an annual output of more than 320 million plants per year. [0004] Traditional mango seedling breeding methods are: [0005] (1) Seed kernel processing: select relatively large seed kernels, after cooling and drying, carefully re...

Problems solved by technology

[0008] Since mango is a tropical fruit, continuous cropping is very easy to be infected by viruses, which in turn reduces yield and quality
