The invention discloses a method for breeding a high-yield shiny-leaved yellowhorn strain. The method comprises the following steps: collecting open pollinated seeds of shiny-leaved yellowhorn, identifying a male parent with an SSR (signal sequence receptor) molecule marker after the seeds germinate and screening mother plants with the self-compatibility of above 60%, with the fertile ovule rate of above 90% and with the seed yield per plant of above 30% higher than that of a contrast tree under same conditions; taking a sapling in a shiny-leaved yellowhorn container as a rootstock, grafting ascion of a selected single plant and identifying a male parent of a seed produced by the single plant; performing second generation grafting and identifying a male parent after the seed is verified as a selfing seed; determining that a mother plant is a final selection single plant if the seed is verified as the selfing seed again; taking a scion of the final selection single plant, taking a seedling of five years plantation of shiny-leaved yellowhorn as a rootstock, grafting the scion of the final selection single plant and expanding propagation, so as to obtain the self-fertility high-yieldshiny-leaved yellowhorn strain. According to the method, a self-fertility high-yield fine breed of the shiny-leaved yellowhorn is cultivated by adopting means such as the SSR molecule marker, seedling raising in the container, grafting and the like, so that the problem of lack of the high-yield fine breed of the shiny-leaved yellowhorn is solved.
