在“冬灵白”大葱采种田中发现了雄性不育株 ,当年选择 6个单株进行开放授粉 ,最后收获 3个单株的种子播种成株系。第 2年从 1个不育株率高的株系中选择优株与原群体的可育株成对杂交 ,父本同时自交 ,连续 4代选择 ,最后选留 0 2 5不育株系与相应父本混合授粉 ,连续 4代不育株率均为 10 0 % ,不育度也为 10 0 % ,简称2 44A ,相应父本简称 2 44B。 2 44A授粉后能正常结实。以 2 44A为母本配制的杂交组合表现出很强的产量优势 Six male sterile plants were found in “Donglingbai” green onions planting. In the same year, 6 plants were selected for open pollination, and the seeds of 3 individual plants were harvested and sown into lines. In the second year, one elite line was selected from one line with high rate of infertile plants. The elite lines were crossed with the fertile lines of the original population at the same time. With the pollination of the corresponding male parents, the average rate of 4 generations of sterile plants was 100% and the sterility was 100%, which was abbreviated as 2 44A, and the corresponding parent was abbreviated as 2 44B. 2 44A can pollinate normal fruiting. The hybrid combination with 2 44A as the female showed a strong yield advantage
