Breeding method for rapid cultivation of loquat hybrid new varieties

Abstract

The invention belongs to the technical field of loquat breeding, and discloses a breeding method for rapid cultivation of loquat hybrid new varieties. The breeding method includes the steps: selectingparents and culturing seedlings in a greenhouse; blossoming and bearing fruits after the juvenile phase of plants is finished, and screening and identifying superior plants. Grafted seedlings can keep the characters of variety scions, rapidly grow and are strong in tree vigor and early in fruiting. Stocks are transplanted in a root cut and half disleaved manner, lateral roots and fine roots are facilitated, and grafting survival rate can be increased. The tree vigor and the resistance of the stocks can be adjusted. A root control seedling culture container has the functions of increasing thelateral roots, controlling main roots and promoting growth, the lateral roots are thick and short in shape, no winding root plates are formed, total root quantity can be increased by 30-50 times, transplanting survival rate can reach 98% or more, seedling culture period is shortened by one half, and post-transplantation management cost is reduced by 50% or more. Light transmission and air permeability are good, shoots are thick and strong, crowns are balanced, and flower bud differentiation is facilitated. Tree nutrition can be improved, flower bud differentiation is promoted, and time limit is shortened by two years or more.

Description

technical field [0001] The invention belongs to the technical field of loquat breeding, in particular to a breeding method for quick cultivation of a new loquat hybrid variety. Background technique [0002] Loquat is a famous and characteristic tree species native to my country, and its resources are extremely rich. How to correctly select and match parents, cultivate new loquat varieties with independent intellectual property rights suitable for the tastes of various groups of people, and transform my country from a country with large loquat resources into a loquat breeding powerhouse that continuously introduces excellent new varieties is the requirement for building an innovative country . Due to the popularization and application of grafting technology, the space for seed selection has become smaller and smaller. For a long period of time in the future, hybrid breeding will still be the dominant method of loquat breeding. Plant resistance, fruit size, edible rate, and co...

Problems solved by technology

[0004] In summary, due to the long time for the hybrid progeny seed lines to complete the transformation from vegetative growth to reproductive growth, the selection of optimal strains for genetically stable traits, and the verification of their genetically stable traits by regional experiments, the existing breeding technology has caused Due to technical problems such as large investment in human, material and financial resources, low conversion rate of achievements, and slow progress in sustainable development, it usually takes 10 years or more to breed a new hybrid variety, seriously reducing economic benefits
