摘要
国内首次发现柱花草显性细胞核雄性不育柱花草种质——1979柱花草,该种质套袋不结实,异交结实正常,小孢子发生异常,花药不开裂,与其他品种(系)的杂交后代出现雄蕊育性分离,雄性不育株与雄性可育株的比例为48:52。
The dominant nuclear male sterility genetic resource： Stylosanthes guianensis TPRC 1979 was discovered for the first time in China. The germplasm doesn＇t fructify when set in bag, fructifies as usual when cross-fertilized. The microspore is abnormal. The anther does not crack. The posterity of the germplasm shows stamen separation when cross-fertilized with other species. The ratio of the male sterility and male viability is 48 ： 52.
