Method for selecting head rice rate of low-generation rice

The invention discloses a method for selecting the head rice rate of low-generation rice. The method comprises the following steps: (1) unhulling rice; hulling the rice material through a rice huller to obtain brown rice of to-be-detected low-generation rice, and sorting out a plurality of experimental groups with the same weight; (2) properly damaging; counting the brown rice of the plurality of experimental groups in the step (1) by using a grain counter, and then properly damaging the brown rice by using a shaking table; (3) efficient sorting; sorting out complete rice grains with embryos and broken rice grains according to different grain sizes, and counting the number of the complete rice grains; and performing low-temperature preservation on the complete rice grains with embryos obtained after the test as breeding intermediate material germplasm, and calculating the percentage of the number of the complete rice grains with embryos to the total number of the tested brown rice. The method has the advantag
