| 摘 要： | 选用广东地区７个早籼品种作亲本，组配成１２对正反交组合，在对亲本及其子一代胚乳蛋白进行等电聚焦－聚丙烯酰胺凝胶电泳分离及扫描定量基础上，确定了最高营养ｐＩ范围蛋白组分之相对含量，用统计学方法分析该相对含量的亲子关系。结果表明，亲本与子代在胚乳蛋白最高营养ｐＩ范围组分含量上呈显著正相关，且子代与母本的相关较父本密切。

| Abstract: | Seven early indica rice varieteies cultivatied in Guangdong were selected as parents, making twelve pairs of reciprocal combinations, to determine the relative content of the pI (isoelectricpoint) range protein components of the highest nutrition based on the isoelectrofocusing-polyacrylamide gel electrophoresis (IEF-PAGE) separation and the quantity fixed according to the scan, in an attempt to find out the parent-descendant (F 1) relationship in the relative content by statistics. The result indicated that there was a significantly positive correlation between parents and their next generation which was more closely related to the female parent than to the male parent. The result with the study method has important significance in the nutrition quality breeding of rice proteins. |
