对于育性恢复基因的地理分布,在粳杂优上,石岭行男曾对日本地方品种进行过研究。我国的洪德林等对BT型,滇型、L型,印野型和野败型五种质源的粳稻雄性不育系的育性恢复基因也进行过研究。在籼杂优上,苏泽胜等认为:某些安徽籼型水稻地方品种对野败不育系有一定的恢复能力。在雄性不育细胞质地理分布研究方面,H、I、OKa博士认为:亚洲、美洲存在有O.perennis的雄性不育细胞质,而非洲和大洋洲则不存在。然而,对籼型野败不育系育性恢复基因及不育胞质地理分布还没有进行过系统的研究;在野败籼型水稻杂种优势利用中,目前 For the geographical distribution of fertility restorer genes, on the japonica heterosis, Shihlin had studied Japanese landraces. Hongdelin et al. Studied the fertility restorer genes of japonica CMS in five types of BT type, Dian type, L type, Indian type and wild type. In indica heterosis, Su Zesheng et al .: Some Indica rice landraces in Anhui have some resilience to the sterile line. In the study of the geographical distribution of male sterile cytoplasm, H, I, OKa, PhD think: O. perennis male sterile cytoplasm exist in Asia and the Americas, while Africa and Oceania do not exist. However, no systematic studies have been carried out on the geographical distribution of sterile restorer genes and sterile cytoplasm in indica wild-sterile line. In the utilization of heterosis of wild proven indica rice,
