Abstract: The thousand-grain weight and the rate of sterile spikelet for varieties of weak springness wheat shewed very notable negative correlation. The scope of optimum temperature during heading-ripening was 21-26℃. The thousand-grain weight and the days from heading to ripening showed very notable positive correlation. From heading to ripening, the thousand-grain weight and the mean of average day temperature showed negative correlation, and the average of day highest temperature showed very notable negative correlation, but with the average temperature differences between days and nights showed very notable positive correlation.

Key words: Weak spriugness wheat, Thousand-grain weight, Rate of sterile spikelet, Air temperature
