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 (CMC1ps2和 2 2 2 )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 .2 5 %～ 10 .83 %,其中正常果率只有 3.8%～ 6 .2 %,利用人工自交可获得 10 0 %的不育后代。 The results showed that the CMS male sterile lines (CMC1ps2 and 2222) containing ps2 male sterility genes introduced from Bulgaria were initially observed under natural conditions in the field. The results showed that their male sterile traits were stable, the stamens and pollen development were normal, Anther not cracking, field self-fertility rate of 5.52% to 10.83%, of which the normal fruit rate of only 3.8% to 6.2%, artificial self-fertilization can be obtained 100% of the male sterile.
