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.
