云粳19号是常规优质粳稻新品种,杂交组合为云粳13号/云粳12号,经4年6代系统选育而成。从集团单株选拔开始,每年对系统材料进行严格的产量、品质、稻瘟病抗性和耐寒性四特性同步鉴定,确保了优良性状定向积累。该品种具有优质、高产、广适、多抗等特点。通过对云粳19号株型、穗型、米质以及产量性状等方面进行剖析,认为选育优质水稻品种,应加强优异稻种资源的收集、研究和利用,并开展产量与品质性状的相关研究以及加强优质稻栽培技术研究。
Yunjing 19 was a conventional high-quality new japonica rice variety. Yunjing 13 and Yunjing 12 were the cross combinations. From the beginning of the single plant selection, the annual strict system of material yield, quality, blast resistance and cold tolerance four characteristics simultaneously identified to ensure the orientation of the accumulation of good traits. The varieties of high quality, high yield, widely adapted, multi-resistance and so on. Through analyzing the plant type, panicle type, grain quality and yield traits of Yunjing 19, we think that breeding high-quality rice varieties should strengthen the collection, research and utilization of excellent rice seed resources, and carry out the correlation between yield and quality traits Research and strengthen the research of high quality rice cultivation techniques.
