| Abstract: | Hybrid wheat seed production continues to be a major constraint in a wider application of hybrids. Improving rate of out-crossing seedy is one of the critical reasons of higher yield of hybrid wheat seed production. In recent years, some progress has been made in studies on out-crossing seedy in male-sterile wheat. This paper briefly describes the progress in flowering habits and characters of flower organs of male sterile lines and restorer lines in wheat. Future research directions are pointed out in this review. |
