中文摘要：

改进谷物质量是在引起新精英米饭变化的一个重要目标，要求为目标遗传型的鉴定的有效工具。分子的帮助标记的选择(妈) ，与常规繁殖途径结合了，使我们能精确识别与不同谷物质量特征被联系的单个遗传型，它能戏剧性地改进繁殖效率。迄今为止，然而，分子的标记的数字在妈使用了因为谷物质量改进仍然是有点有限的。在这研究，基于我们米饭谷物质量强烈在内乳与淀粉合成被联系的以前的学习，我们在 18 淀粉根据顺序变化开发了 51 个标注基因的分子的标记从 16 典型米饭栽培变种的合成相关的基因。这些标记能在米饭 germplasms 之中区别不同等位基因。这些新奇标记将在经由繁殖改进谷物质量提供有效工具新精英米饭变化。

英文摘要：

Improving grain quality is an important goal in breeding new elite rice varieties, requiring effective tools for the identification of target genotypes. Molecular marker-aided selection （MAS）, combined with conventionai breeding approaches, enables us to pre- cisely identify the individual genotypes that are associated with different grain quality features, which can dramatically improve the breeding efficiency. However, to date, the number of molecular markers used in MAS for grain quality improvement is still somewhat limited. In this study, based on our previous study that rice grain quality is strongly associated with starch synthesis in the endosperm, we developed 51 gene-tagged molecular markers according to sequence variations in 18 starch synthesis-related genes from 16 typical rice cultivars. These markers can discriminate the different alleles among rice germplasms. These novel markers will provide effective tools in improving grain quality via the breeding new elite rice varieties.
