Abstract

The invention discloses a method for breeding yellow-leaf red-rice paddy rice. The method comprises the steps that firstly, hybridization is performed on paddy rice with red seed coats and green leaves and paddy rice with yellow leaves, then backcross is performed many times on the paddy rice with the yellow leaves as a male parent, then multi-generation self-cross is performed, screening is performed according to a target character, and the obtained yellow-leaf red-rice paddy rice has yellow leaves, red seed coats, a sowing period less than 100 days, and a plant height less than 100 centimeters, does not have leaf diseases in the whole duration period, and has the edible quality reaching the secondary standard requirements of red rice, significantly increased ornamental value and edible and nutritional value.
