Embodiment Construction

[0022] 1. Scion preparation

[0023] If you want to branch in spring, you should select the branches with good growth, no pests and diseases, and suitable thickness among the cut annual branches during pruning in the previous winter. The scion of annual grafting is used.

[0024] The scions of the eight apple varieties (namely Jinshuai, American No. 8, Honeycrisp, Qinguan, Shouhong, Hongai, Pink Lady and Longhongmi) that had been cut were grouped into bundles, marked and buried in the In the cool and slightly damp sandy soil, prevent water evaporation to maintain the vitality of the scion and delay the germination time of the branches. Before burying in sandy soil, the two ends of each scion are coated with paraffin to better prevent moisture from evaporating. When burying in sand, be sure to make a record of the burying address, so that it is easy to find in the coming year. When grafting in the spring of the second year, take out the scion buried in the sand and use it, a...

Abstract

The invention relates to a top grafting method for obtaining hybrid seeds of 8*9 apple multi-varieties; 3 to 5 years old robust apple trees are selected as mother plants, wherein Longfu short branch is selected as a mother plant variety; Golden delicious apples, US No.8 apples, Honeycrisp apples, Qinguan apples, Shouhong apples, hongai apples, Pink Lady apples and Longhongmi apples are selected to be multi-head top grafted on the apple mother plants as female parents; after fruiting, fruits are classified and picked according to the female parents to obtain multiple variety hybridization apple seeds; laminated sowing is performed in the second year for further sowing observation in the next year. The method utilizes the characteristics of apples of cross pollination, varieties of flowers have close contact, in the pollination process, to be pollinate naturally; fruits with different parents can be obtained without the help of human forces; the method has simple operation; one time of grafting and hybrid seed harvesting for years is fulfilled.

Description

technical field [0001] The invention relates to a method for obtaining hybrid seeds by high-grafting of multiple varieties of 8×9 apples, in particular to a method for cultivating hybrid offspring by natural hybridization of multi-variety high-grafting per apple plant and belongs to the field of fruit tree breeding. Background technique [0002] With the rapid expansion of my country's apple cultivation area, the quality requirements for apples in the market have increased significantly. Whether it is from the perspective of consumers or growers, the innovation of apple varieties is particularly important. [0003] At present, there are many methods of apple breeding. Although hybrid breeding is ancient, it still occupies a dominant position. For example, the main apple varieties 'Fuji', 'Gala', 'Qinguan', 'Huaguan', and 'Jonah' are widely cultivated in China. Jin', the main varieties 'Braeburn', 'Pink Lady', 'Micrispy' and 'Pacific Rose' widely cultivated in Europe and Amer...
