【摘要】 1996~1997 年进行了饲料稻品种(组合)的筛选试验,初选出 4 个高产高蛋白杂交饲料稻组合供近期生产上主推应用。研究发现,杂交组合的蛋白质含量受恢复系的影响较大,产量与蛋白质含量、蛋白质含量与出糙率之间均不存在显著的直线相关关系。杂交组合出糙率可达到 80% ,但高产与高蛋白结合的组合极少。选育高蛋白恢复系是选育高蛋白组合关键之一。

【Abstract】 In the experiments for screening fodder rice varieties (combinations) in 1996 and 1997, four hybrid combinations with high yield and high protein content were selected as fodder rice for commercial production in the coming years. It was found that the protein content of hybrids was affected by their restorer lines; there was not a significant linear correlation both between grain yield and protein content and between protein content and brown rice recovery. The brown rice recovery of the hybrid combinations is as high as 80%, but there are few combinations with both high yield and high protein content. To breed high protein combinations, the key seems to select high protein restorer lines.
