Rice yield is subjected to severe losses due to adverse effect of a number of stress factors. The most effective method of controlling reduced crop production is utilization of host resistance. Recent technological advances have led to the improvement of DNA based molecular markers closely linked to genes or QTLs in rice chromosome that bestow tolerance to various types of abiotic stresses and resistance to biotic stress factors. Transfer of several genes with potential characteristics into a single genotype is possible through the process of marker assisted selection (MAS), which can quicken the advancement of tolerant/resistant cultivars in the lowest number of generations with the utmost precision through the process of gene pyramiding. Overall, this review presented various types of molecular tools including MAS that can be reasonable and environmental friendly approach for the improvement of abiotic and biotic stress resistant rice with enhanced quality.
由于多种胁迫因素的不利影响，水稻产量遭受严重损失。控制作物减产最有效的方法是利用宿主抗性。最近的技术进步导致了与水稻染色体上赋予对各种非生物胁迫耐受性和对生物胁迫因子抗性的基因或QTL紧密连锁的基于DNA的分子标记的改进。通过标记辅助选择（MAS）过程，可以将几个具有潜在特性的基因转移到单个基因型中，通过基因聚合过程，该方法可以以最高的精度在最少的世代数中加速耐受性/抗性品种的培育。总体而言，本综述介绍了包括MAS在内的各种分子工具，这些工具对于改良具有更高品质的抗非生物和生物胁迫水稻来说，可能是合理且环保的方法。
