Abstract: The purposes of this study were to examine growth period, plant height, effective panicles and yield performance of the offspring of sterile line‘Ming S’and restorer lines, and provide the basis for‘Ming S’ preparation with other high-yielding combinations. Using eight sterile lines including‘Ming S’with close growth period making sets with the same R- line‘R900’, the seeds of F1 were sowed. Under the same cultivation condition of water and fertilization, the growth period, plant height, effective panicle traits and yield performance of eight combinations were recorded. Results showed that the duration of Ming S/R900 was 84 d, and it had the longest growth period, 148d. The plant type of Ming S/R900 was relatively short, which was 117 cm, and its yield was 12.9 t/hm2, increased by 1.26 t/hm2 compared with that of‘Shuang Liangyou 1000’. Ming S/R900 also had strong tillering ability, the number of effective panicles was 15.3 per plant and 2.5245 million per hectare, 54.3% more than that of Long 638 S/R900. The seed setting rate was 93.91%, the number of solid grain of Ming S/R900 was 211.96 per panicle, and it also had resistance to the purple sheath disease. The characteristics of Ming S/R900 showed that it had high seed setting rate, and good combining ability.
