| 摘 要： | 1998年以来,从美国农业部戴尔帮佩国家水稻研究中心,引进水稻资源778份。通过隔离检疫后,以中国恢复系明恢复63作为对照,选择美国、哥仑比亚、韩国、巴西、意大利五个国家培育的生育期与对照接近的水稻品种各10个。对其主要的产量与品质性状,进行了田间试验与实验室考种,对试验资料进行了统计分析。结果表明:引进的品种产量都比中国四川目前栽培的品种低,但品质普遍较优。这些品种都不能够直接用于生产,但作为育种亲本材料有一定利用价值。 |

| Abstract: | Seven hundred seventy-eight accessions of rice germplasm were introduced from the United States Department of Agriculture,Agricultural Research Service(USDA-ARS) rice germplasm collection since 1998.After quarantined in isolated area,ten accessions each from USA,Colombia,Korea,Brazil and Italy were selected for field and laboratory evaluations in comparison with Minghui 63,major restoring line for rice hybrids in China.The selected accessions had similar maturity with the Chinese check,Minghui 63.These foreign lines did not yield as much as Minghui 63,but most of them had better grain quality than Minghui 63.Some characteristics should be valuable in our breeding programs,but it is not feasible to make use of foreign cultivars in rice production directly. |
