摘要: 对从保加利亚引入的含有ps-2 雄性不育基因的番茄雄性不育品系(CM C1ps2 和222) 在田间自然条件下进行初步观察, 结果表明其不育性状表现稳定, 雄蕊、花粉发育均正常, 花药不开裂, 田间自交坐果率5. 25 %~10. 83 % , 其中正常果率只有3. 8 %~6. 2 % , 利用人工自交可获得100 %的不育后代。

Abstract: Some lines with ps-2 male sterile gene were introduced from Bulgaria. The results observed in the open field proved that their sterility was stable without emasculation. The plants had normal stamen and pollen , and
indehiscent anther. The percentage of selfing fruits was about 5. 25 % - 10. 83 %. Among them , the normally developed fruits with seeds occupied only 3. 8 % - 6. 2 %. Furthermore , the male sterile lines can be maintained
easily by artificial pollination.
