Example Embodiment

[0022] Example 1:

[0023] A method for cultivating apple early-flowering and early-fruit rootstocks quickly into production, including the following steps:

[0024] (1) Obtaining offspring of hybrid breeding

[0025] 1) Collection of male parent pollen: In the spring of 2000, in the early flowering period of the apple, pick the Begonia rotundifolia bell flowers, collect the anthers indoors, and spread them in a cool and windless place in the newspaper room to dry naturally. When the anthers are dry and the pollen bursts, be careful Collect pollen in a dry penicillin bottle, and seal it to prevent recurrence;

[0026] 2) Hybrid pollination: In the same year, in sunny and windless weather, after artificially emasculating the sea red bell flower, pollinate the male parent pollen to the female parent sea red bell style stigma by dipping with a brush, wrap it in a paper bag and seal it, 3-5d Back unpacking

[0027] 3) Collection and sowing of hybrid seeds: in the autumn of that year, pick...

Abstract

The invention belongs to the field of plant breeding and in particular relates to a method for rapidly breeding early blooming and fruiting stock of apples. The method comprises the following steps: (1) acquiring crossbreeding descendants; (2) primarily selecting early blooming and fruiting stock of apples; (3) performing local experiments on the early blooming and fruiting stock of apples. By adopting the method, the breeding cycle can be greatly shortened by 3-5 years.

Description

Technical field [0001] The invention belongs to the field of plant breeding, and specifically relates to a method for rapid selection and breeding of apple rootstocks for early flowering and early fruiting. Background technique [0002] A good apple rootstock is the basis for high quality and high yield of apples. The breeding cycle of apple rootstocks is very long. It is necessary to observe the rooting by layering and cutting methods on the premise of preserving the mother of the hybrid offspring. Only those who are easy to root can enter the next stage of early flowering and early fruiting regional trials. This primary selection process will take at least 3 years. After completing the preliminary screening for rooting, it is necessary to continue to reproduce those who are easy to take root, and the number of each offspring is more than 50, before continuing the next stage of the regional test, this reproduction process should be at least 3 years. At the same time, an ordina...
