【摘要】 云粳优5号的母本是云粳优1号,父本是云粳优2号,经4年6代选育而定名。选育过程中,从集团单株选拔开始,每年都对高产性、品质、稻瘟病抗性、耐寒性进行同步鉴定,作为选拔的科学依据。云粳优5 号具有稻米品质好、香味浓郁、产量高和适应性广等特点。根据该品种选育的成功经验,在今后品质育种中, 以加强优异稻种资源的收集、研究和利用为基础;继续特质米育种和高整精米率育种;重视减少黑褐色斑点米育种研究;加强优质稻栽培技术研究。更多还原

【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.更多还原
