Embodiment 1

[0034] Embodiment one: shorten the method for the infancy of Korla fragrant pear directional breeding hybrid seedling

[0035] The method for shortening the infancy of Korla fragrant pear directional breeding hybrid seedlings is carried out seedling raising and cultivation by following method, and concrete method step is as follows:

[0036] (1) Korla fragrant pear hybrids sowed in the greenhouse in the same year and raised seedlings

[0037] (1) Picking of Korla fragrant pear hybrid fruit: pick Korla fragrant pear hybrid fruit with suitable maturity between 6 am and 8 am, and handle it with care to avoid mechanical injury.

[0038] (2) Stripping and cleaning of Korla fragrant pear hybrids: refrigerate the Korla fragrant pear hybrids harvested in step (1) for 3 days in a cold storage, where the temperature of the cold storage is 4°C; after the cold storage, take out the Korla fragrant pear hybrids The fruit is removed, the pulp is removed, the hybrid seeds are taken out, the ...

Embodiment 2

[0059] Embodiment two: shorten the method for raising seedlings in childhood of Korla fragrant pear directional breeding hybrid seedlings

[0060] Pick the mature Korla fragrant pear hybrid fruits between 6:00 and 8:00 in the morning, and refrigerate them in the cold storage for 3 days. After the refrigerating, take out the hybrid seeds, rinse the hybrid seeds with clean water for 5-8 minutes, and wash off the sticky substances and residues on the surface of the hybrid seeds For the pulp, obtain the Korla fragrant pear hybrid, soak it in clean water for 24 hours, gently remove the seed coat of the Korla fragrant pear hybrid with tweezers, remove the seed coat of the Korla fragrant pear hybrid in 0.35mg / L of Gibberella Soak in plain solution for 12 hours, mix the Korla fragrant pear hybrid and wet sand evenly according to the weight of Korla fragrant pear hybrid: the weight of wet sand is 1:5, and put it into gauze, and wrap the gauze at the same time Embed in a sand storage co...

Embodiment 3

[0061] Embodiment three: shorten the method for the childhood management of Korla fragrant pear directional breeding hybrid seedling

[0062] Fertilizer and water management for Korla fragrant pear hybrid seedlings: irrigate once every 20 days, and the amount of water each time is 30m 3 / mu. The irrigation method is easy to use side irrigation, that is, irrigate on one side of the ridge to avoid direct contact of the tree trunk with open water. In order to ensure the rapid growth of hybrid seedlings, one month after transplanting hybrid seedlings, combined with irrigation, topdressing urea 5.0kg / mu, once every 20 days; Quantitative change: 60m 3 / mu, combined with irrigation and fertilization amount becomes: urea 15.0kg / mu. Hybrid seedlings are prone to damping-off disease in the early stage, which can be controlled by alternate spraying with carbendazim, chlorothalonil, thiophanate-methyl and other agents, spraying once every 15 days; The amount of growth and the growth o...

Abstract

The invention discloses a method for shortening the juvenile period of directive breeding hybrid seedlings of Pyrus bretschneideri Rehd. The method adopts sowing and greenhouse seedling raising in the same year, and comprises the following steps: removing seed coat, carrying out gibberellin treatment, spraying GA3 in the growing period of the hybrid seedlings, conducting inversed ring-bark grafting on the hybrid seedlings sprayed with GA3, carrying out hybrid seedling terminal bud grafting, dwarfing stock, spraying chlormequat chloride (CCC), and various other technical measures, so as to shorten the juvenile period of the directive breeding hybrid seedlings of Pyrus bretschneideri Rehd. According to the method, the Pyrus bretschneideri Rehd. hybrid seedlings can bloom and fruit in the third year after being planted, and the fruiting plant rate can be 30 percent, while the conventional Pyrus bretschneideri Rehd. hybrid seedlings bloom and fruit 7 to 8 years after being planted. Being treated with the six measures, the Pyrus bretschneideri Rehd. directive breeding hybrid seedlings can fruit in the third year after being planted, that is, the juvenile period is shortened by 4 to 5 years. Therefore, the Pyrus bretschneideri Rehd. directive breeding efficiency is greatly improved; the Pyrus bretschneideri Rehd. directive breeding period is shortened; a new way and a new method are provided for breeding of new Pyrus bretschneideri Rehd. directive breeding varieties; the application value is high.

Description

field of invention [0001] The present invention relates to the technical field of plant breeding. Specifically, the invention relates to the technical field of Korla fragrant pear directional breeding hybridization. Background technique [0002] Korla Fragrant Pear (Pyrus bretschneideri Rehd) belongs to the white pear system of Rosaceae, Pomoideae, and Pyrus. Dengmu, native to the Korla region of Xinjiang, has been cultivated in Xinjiang for more than 1,400 years. Its fruit is rich in fragrance, thin in skin and crisp in flesh, sweet and refreshing, tender and juicy, and has strong storage resistance. It is one of the four famous pears in my country. In 2014, the total cultivation area of ​​Xinjiang Korla fragrant pears reached 988,700 mu, with a total output of 1,044,800 tons. The Korla fragrant pear industry has become the leading industry in the Korla area; in China, the Korla fragrant pear is the pear variety with the highest market share in my country, the widest sales ...
