摘要
利用裂颖率指标 ,对 10 17份水稻资源进行抗裂颖种质筛选 ,筛选出 13份高抗与高感的种质资源。利用已筛选资源 ,估算水稻品种 (系 )裂颖率的广义遗传率为 94 8%。纯系选择试验、不同播期试验及不同氮肥施用水平试验的结果表明 ,水稻品种 (系 )抗裂颖性状是稳定的可遗传性状 ,其表达不受环境因素影响。
Using the percentage of gaping glume (PGG) as an index, thirteen accessions of high resistance and high susceptible PGG rice resources were selected from 1017 varieties preserved by the Insititute of Rice Research, Anhui Academy of Agricultural Sciences. With the selected varieties(lines), the broad heretability (h 2) was estimated to be 94 8%. The results of pure line selection, different sowing dates and different fertilizer experiments indicated that the character of glume gaping resistance in rice varieties is stable and heritable, and the environmental factors have no effects on its expression.
