继产量之后，品质是水稻育种的重要内容之一。不同文化和地区对稻米质量的偏好各不相同;因此，稻米育种者必须根据当地消费者的偏好调整稻米质量。稻米品质评估需要常规的化学分析程序。分子标记技术的发展使育种策略发生了革命性的变化。水稻基因组序列的可用性以及正向和反向遗传学方法的使用促进了基因发现和基因功能的破译。功能标记在植物基因分型，特别是标记辅助育种中起着重要作用。此外，功能性标记物提供了抵消随机DNA标记物的局限性的优点。一些功能标记已被应用于分子标记辅助育种，并成功地改良了稻米品质，以满足当地消费者的偏好。尽管功能标记相对于随机遗传标记具有许多优势，但功能标记的开发和应用仍需谨慎。测序成本的降低将使更多的稻米品质改良功能标记得以开发，这些标记在稻米品质育种中的应用备受期待。
After yield, quality is one of the most important aspects of rice breeding. Preference for rice quality varies among cultures and regions; therefore, rice breeders have to tailor the quality according to the preferences of local consumers. Rice quality assessment requires routine chemical analysis procedures. The advancement of molecular marker technology has revolutionized the strategy in breeding programs. The availability of rice genome sequences and the use of forward and reverse genetics approaches facilitate gene discovery and the deciphering of gene functions. A well-characterized gene is the basis for the development of functional markers, which play an important role in plant genotyping and, in particular, marker-assisted breeding. In addition, functional markers offer advantages that counteract the limitations of random DNA markers. Some functional markers have been applied in marker-assisted breeding programs and have successfully improved rice quality to meet local consumers’ preferences. Although functional markers offer a plethora of advantages over random genetic markers, the development and application of functional markers should be conducted with care. The decreasing cost of sequencing will enable more functional markers for rice quality improvement to be developed, and application of these markers in rice quality breeding programs is highly anticipated.
