两系杂交水稻组合培杂民科占种子纯度的快速鉴定

Genetic Purity Testing of Seed from Two-line Hybrid Rice(Oryza spp.) of Variety Peizaminkezhan

利用超薄等电聚焦电泳技术对两系杂交水稻组合培杂民科占的种子纯度进行了鉴定。结果表明:用超薄等电聚焦电泳技术鉴定的种子纯度和田间小区种植鉴定的纯度完全吻合,且成本更低,速度更快,值得推广应用。

Uhrathin-layer isoelectric focusing of seed proteins（UTLIEF） test were used to test the genetic purity of hybrid rice seeds. Results showed：Genetic purity determined by UTLIEF was the same as that of grow-out test and UTLIEF cost less money and fewer hours than grow-out test.
