摘　　要：黄华占是由黄新占与丰华占杂交育成的早中晚稻兼用型优质稻核心种质,黄华占产量高于杂交稻汕优63,米质达国标1级,抗稻瘟病和白叶枯病,具有较好的耐热性,同时还是一个两系恢复系。由黄华占衍生出的4个品种通过了广东省品种审定。黄华占的育成与利用证明了水稻核心种质育种的高效性。Huanghuazhan, a core germplasm which can be planted as early, medium or late rice, was bred from crossing Huangxinzhan and Fenghuazhan. Its yield was higher than hybrid rice-Shanyou No. 63, its rice quality grades GB 1. It is resistant to blast and bacterial blight with good tolerance to high temperature. And it could double as restorer line in two-line hybrid system. Four varieties derived from Huanghuazhan have passed the varietal examine and approval by Guangdong Province. Successful breeding and application of Huanghuazhan has proved the high effi- ciency of rice core germplasm breeding.
