【Abstract】 Yunjingyou 5 was bred by crossing, using Yunjingyou 1 as maternal parent and Yunjingyou 2 as paternal parent through four years and six generations selection. Yield, quality, blast resistance and cold endurance were evaluated synchronously from F2 generation. Evaluating results provided scientific basis for selection. It has good quality, strong fragrance, high yield, wide adaptability traits and so on. According to successful breeding of Yunjingyou 5, many works should be done about rice breeding with good quality in future. Collecting, evaluation and usage excellent variety resource must be strengthened. The special quality rice breeding and high head rice breeding will be continued. The study on reducing black-speckle and culture with good quality also must be paid great attention to.
