Problems solved by technology

Early-maturing peach varieties have the advantages of early maturity, relative cultivation and management, and high economic benefits, but they generally have the disadvantage of poor fruit quality. Therefore, breeding early-maturing peach new varieties with good quality and early maturity is one of the important tasks of peach breeding. one

Embodiment 1

[0015] A method for selecting and cultivating a new variety of Jinliuzaohong peach tree. Firstly, select the species, and select a branch that is obviously different from other fruits in the whole peach tree. If the fruit on this branch is obviously larger than other fruits, then Mark the branch and observe it; then graft the branch with special fruit in late August, graft it to many different peach trees, observe the fruit it bears three years later, and observe the fruit The various indicators of the peach tree are compared with the fruiting characters of the original mother branch. If they are the same, select a relatively strong peach tree from among the many peach trees to take buds and start the second generation of reproduction. Three years after the second generation is grafted, it will start to bear fruit , and then observe the fruit it bears, and compare the various indicators of the fruit with the fruiting characters of the original mother branch. If the result is th...

Embodiment 2

[0017] The fruit grower found in the orchard that the two fruits on the back of a main branch of a 3-year-old common peach tree (commonly known as white peach in the local area) were particularly large and had begun to color. At that time, the whole tree, including other trees of the same species in the entire orchard, produced very small fruits. According to the analysis of biological characteristics, the fruits had just entered the hard-core stage, which was similar to the two newly discovered fruits at that time. The phenomenon difference is very obvious. Immediately marked and observed, in late August of that year, the branches growing special fruits were grafted, and a total of 18 trees were grafted at that time. Three years later, all the 18 grafted trees bear fruit, and the indicators of the fruit bear are basically consistent with the fruiting properties of the original mother branch. In the coming year, 2 trees with relatively strong growth will be selected from these...

Abstract

The invention provides a seed selection and cultivation method for a novel-variety Jinliu early-red peach tree. The seed selection method for the novel-variety Jinliu early-red peach tree is characterized by comprising the steps that seed selection is carried out, a branch with fruits obviously different from other branches is selected from the whole peach tree, and the branch is marked and observed if the fruits on the branch are obviously larger than other fruits; a traditional tree fruit breeding method is combined with the modern molecular biological technique, precocious peach breeding work is carried out, and the effect is significant. On the basis of bud mutation, seed selection, top grafting identification, clone breeding and the like in the fruit tree breeding theory, an SSR and SRAP molecular marker technology is further utilized for bud mutation identification, the genome DNA variation range and site are found, it is verified that the genes of the novel variety are changed, true bud mutation occurs on the novel variety, and the good property can be stably inherited.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for selecting and cultivating a new variety of Jinliuzaohong peach tree. Background technique [0002] Peach is one of China's advantageous products. China's peach output and export volume both rank first in the world. In recent years, the price of apples, pears and other fruits has continued to decline, and the price of peaches has risen steadily. [0003] As we all know, the sustainable development of the peach industry depends on the continuous introduction of new varieties. Over the past few decades, the research on peach breeding in my country has gone from scratch, from selection to breeding, from traditional breeding to the combination of conventional breeding and biotechnology breeding, and has achieved a remarkable achievement. Early-maturing peach varieties have the advantages of early maturity, relative cultivation and management, and high economic benefits, but they g...
