Efficient breeding method of sugarcane health seedling

Abstract

The invention relates to a high-efficiency breeding method of healthy seedlings of cane, the method is proposed aiming at the problems that seed performance degenerates, yield is greatly reduced and the quality is reduced, which are caused by that the cane is taken as asexually propagated crop, propagation coefficient is low, the amount of seeds used for cane implantation is large, and after the implantation of a plurality of years, the cane is easy to be infected with a disease; improved type healthy seedlings of the cane can be cultured by nine steps of seedling mild water detoxication processing, seedling sprouting, in vitro peeling inoculation, induction culture, virus check, propagation culture, rootage culture, domesticated seedling-refining and outdoor temporary planting; the method adopts the combination of mild water detoxication and stem tip detoxication with thorough detoxication and good effect; the direct peeling inoculation of the explant does not need to be treated withdisinfection processing, has low pollution rate and light browning, and is easy to generate clustering buds by induction; the propagation coefficient is high, the speed is high, the period is short; the seed performance is table, the seedling is strong; the virus detection is precise and accurate; the survival rate of the outdoor temporary planting is high and is up to more than 90 percent; the production cost is low, the efficiency is high, and the method is suitable for industrialized production.

Description

Technical field: [0001] The invention relates to the field of crop seed engineering, in particular to a method for efficiently breeding healthy sugarcane seedlings. Background technique: [0002] Sugarcane is an important sugar crop in my country. The contribution rate of improved sugarcane varieties to the sucrose industry is over 60%. The rapid popularization and application of improved sugarcane varieties has become a direct driving force for the development of the sucrose industry. The amount of seeds used in conventional cultivation is large, and the amount of seeds used per mu is as high as 8,000-10,000 buds. After several years of planting, sugarcane is susceptible to mosaic disease, perennial dwarf disease, etc., resulting in the degradation of the quality of sugarcane varieties, resulting in reduced sugarcane production, Adverse effects such as quality degradation. Therefore, research on the use of healthy sugarcane seedlings as seeds has become a feasible way for th...
