Stock screening method of interspecific hybrid loquat

Abstract

The invention discloses a stock screening method of an interspecific hybrid loquat. Excellent strains are selected from a group of interspecific hybrids; three strains with the best roots are selected from these hybrid progenies as candidate stocks; more than 10,000 strains can be bred from each bud every year. By adopting the method disclosed by the invention, the stock with a deep root can be obtained; the disease of a hollow root of the cultivated loquat is overcome; the stock material of which the graft compatibility is better than that of a wild loquat can be obtained; the phenomenon of graft incompatibility is also overcome.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a rootstock screening method of interspecific hybrid loquat. Background technique [0002] Loquat (Eriobotrya japonica Lindl.) is a subtropical characteristic fruit tree native to my country. It is planted on more than 2 million mu across the country. It consumes more labor and has a higher output value. The output value exceeds 10 billion yuan. Sichuan is the most planted, followed by Fujian. Loquat leaf is also a traditional Chinese herbal medicine for cough relief. [0003] The propagation of loquat traditionally adopts seed propagation, that is, sowing and propagating with seeds. This breeding method causes more variation in the offspring, and the loquats in the entire loquat garden grow irregularly, which is a backward breeding method. Since the seventies of last century, my country has gradually adopted grafting and breeding, and most of the loquat gardens...

Problems solved by technology

Oak leaf loquat is a close relative of common loquat. It also blooms in autumn and winter and matures in spring to early summer. However, the fruit is small and has no value for direct fruit tree cultivation and utilization, but its root system ratio is larger than that of common loquat.
