Abstract：In order to understand the characteristics of three new rice CMS Lines, the growth duration, agronomic characters, flowering habits and the effects of temperature and humidity on the daily flowering were investigated and analyzed. The results showed that the growth duration from long to short is Ming 2A, Ming 1A, Tianfeng A, Ming 6A. The effective tiller number, grains number per panicle, and plant height of the Ming 1A and Ming 2A were significantly higher than those of Tianfeng A.The flowering habit of the four male sterile lines were different, but the flowering time was concentrated, and the flowering peak was concentrated between 12:00 and 13:00. The four male sterile lines had large glume angle, highe stigma exsertion rate and good outcrossing rate characteristics. The correlation analysis showed that the total amount of flowering before noon was positively correlated with temperature, negatively correlated with humidity. In a word, suitable temperature and humidity could promote flowering.
