蓉6优5970是以不育系蓉6A与恢复系德恢5970配组育成的杂交中籼水稻品种,具有产量高、稻米品质优和生育期适中等特点。本文综合其亲本特征特性,总结分析了该品种在四川德阳地区的高产制种技术。其母本蓉6A一般配合力高,不育性彻底且米质优;其父本德恢5970花粉量大,恢复力强且配合力好。其高产制种技术包括选择适宜的制种基地,根据田块情况选择空间或时间隔离;合理安排父母本播种期;科学管理秧田,培育壮秧;适时移栽,合理密植;科学施肥管水,预防病虫害;调节花期;合理喷施植物激素,适时赶粉以及严格去杂,适时收获等。研究结果为该品种高产制种提供参考。

Rong 6 you 5970 is a hybrid indica rice variety developed by combining the sterile line Rong 6A with the restorer line Dehui 5970. It has the characteristics of high yield, excellent rice quality, and moderate growth period. The high-yield seed production techniques of this variety were summarized and analyzed in the Deyang area of Sichuan Province, based on the characteristics of its parents. Its female parent Rong 6A generally has high compatibility, complete sterility, and excellent rice quality; Its male parent Dehui 5970 has a large amount of pollen, strong resilience, and good compatibility. The high-yield seed production technology includes selecting suitable seed production bases, selecting spatial or temporal isolation based on the situation of rhizosphere fields; reasonably arrange the sowing period for parents, scientific management of paddy fields and cultivation of strong seedlings, timely transplanting and reasonable dense planting, scientific fertilization and water management to prevent diseases and pests, flowering period regulation, reasonably spraying plant hormones, timely powder removal, strict impurity removal, and timely harvesting. The research results provide references for high yield seed production of this variety.
