The Occurrence of Sterile Florets in Wheat and Barely in 1998 and 1999 in the Gunma Tohmo Area in Japan

Abstract

We had many sterile florets in barley in 1998 and 1999 in Gunma. This damage was different from that caused by young panicle freezing owing to low temperatures. We thought that the pollen was damaged by the low temperature around heading time, resulting in the sterility. The damage of wheat was relatively small, and a genotypic difference was observed for the occurrence of sterility among barley cultivars.
