Anther dehiscence is very important for pollen maturation and release. The mutants of anther dehiscence in rice (Oryza sativa L.) are few, and related research remains poor. A male sterility mutant of anther dehiscence in advance, add(t), has been found in Minghui 63 and its sterility is not sensitive to thermo-photo. To learn the character of sterilization and the function of the add(t) gene, the morphological and cytological studies on the anther and pollen, the ability of the pistil being fertilized, inheritance of the mutant, and mapping of add(t) gene have been conducted. The anther size is normal but the color is white in the mutant against the natural yellow in the wild-type. The pollen is malformed, unstained, and small in the KI-I(2) solution. The anther dehiscence is in advance at the bicellular pollen stage. A crossing test indicated that the grain setting ratio of the add(t) is significantly lower than that of the CMS line 2085A. The ability of the pistil being fertilized is most probably decreased by the add(t) gene. The male sterility is controlled by a single recessive gene of add(t). This gene is mapped between the markers of R02004 (InDel) and RM300 (SSR) on chromosome 2, and the genetic distance from the add(t) gene to these markers is 0.78 cM and 4.66 cM, respectively.
