Abstract：After years of selection, jinongda 18, a rice variety, has been obtained from the crossing between zupei 7 (female) and 93-14 (male ). The results of 3-year regional trials showed that its yield increased by 5.23% compared with the control variety (tong35). The results of 1-year productive trials showed that its yield increased by 6.0%. It was of good quality, high yield, strong resistance to adverse conditions, and wide adaptability.
