Method for breeding high-yield xanthoceras sorbifolia strain

Abstract

The invention belongs to the technical field of new plant variety cultivation, and discloses a method for breeding a high-yield xanthoceras sorbifolia strain. The method for breeding the high-yield xanthoceras sorbifolia strain comprises the following steps: collecting seeds, breaking a dormancy period, identifying a male parent by adopting an SSR molecular marker after germination and emergence,and screening a high-quality mother plant; taking a xanthoceras sorbifolia container sapling as a stock, grafting a selected single plant scion, identifying a male parent for borne seeds, and performing second-generation grafting and male parent identification after confirming that the seeds are self-fruitful; if seeds are self-fruitful again, determining the mother plant as a final single plant;and taking the scion of the final single plant, taking a 3-5-year-old xanthoceras sorbifolia seedling as a stock, and performing grafting and expanding propagation to obtain a self-fertile high-yieldxanthoceras sorbifolia strain. The method is simple, convenient, trouble-saving, labor-saving and easy to operate; seeding is carried out after dormancy breaking, so that the field seedling rate is increased, and the seed germination and emergence speed is increased; and the problem of shortage of high-yield improved seeds of the xanthoceras sorbifolia is efficiently and rapidly solved, and the urgent need of current xanthoceras sorbifolia industry development is met.

Description

Technical field [0001] The invention belongs to the technical field of cultivation of new plant varieties, and in particular relates to a method for breeding high-yield Aronia fruit strains. Background technique [0002] At present, the closest existing technology: Xanthoceras sorbifolia Bunge., also known as papaya, Wendeng Pavilion, Monk Deng Maodao, belongs to Sapindaceae (Sapindaceae), Xanthoceras, is a single Species, deciduous trees or shrubs, native to northern my country, distributed in the north of the Qinling Mountains and the Huaihe River, south of Inner Mongolia, starting from Liaoning in the east, Qinghai in the west, Henan and northern Jiangsu in the south. As a kind of woody oil-bearing energy tree species, Xanthomonas serrata is very suitable for growing in northwest arid desert regions such as Xinjiang, Shaanxi, Shanxi, Gansu, and Inner Mongolia due to its good biological characteristics such as drought tolerance, cold tolerance, and salt tolerance. The oil conte...

Problems solved by technology

[0005] In summary, the problems in the prior art are: there are uncertain factors in the existing high-yield breeding methods of sorbifolium sorbifolium, and the selected individual plants may not be really excellent, and they are only suitable for specific pollination or specific climate and soil microenvironment. Excellent performance and high yield under the environment, leaving this environment, the traits may be completely different
