Influence of Temperature on a Partially Male-Sterile Soybean Strain1

Abstract

Abstract

Temperature during flowering and pod set influenced degree of sterility in a partially male-sterile soybean strain [Glycine max (L.) Merr.]. Growth chambers, set for 14.5/ 9.5, light/dark sequences in each 24-hour period, were used to present varying day/night temperatures to the growing plants. No pods were set on the male-sterile strain when the day temperature was 35C and the night temperature was either 21 or 27C. Plants were partially fertile, however, when grown 'at a day temperature of either 21 or 29C with a night temperature of 16 or 21C. The largest number of pods was produced on the partially male-sterile strain when the day temperature was 29C followed by a night temperature of 21C. Temperature did not affect number of seeds per pod on the partially male-sterile strain at temperature regimes where pods were formed.
