The main focus of this review is to discuss the current status of the use of GWAS for fodder quality and biofuel owing to its similarity of traits. Sorghum is a potential multipurpose crop, popularly cultivated for various uses as food, feed fodder, and biomass for ethanol. Production of a huge quantity of biomass and genetic variation for complex sugars are the main motivations not only to use sorghum as fodder for livestock nutritionists but also as a potential candidate for biofuel generation. Few studies have been reported on the knowledge transfer that can be used from the development of biofuel technologies to complement improved fodder quality and vice versa. With recent advances in genotyping technologies, GWAS became one of the primary tools used to identify the genes/genomic regions associated with the phenotype. These modern tools and technologies accelerate the genomic assisted breeding process to enhance the rate of genetic gains. Hence, this mini-review focuses on GWAS studies on genetic architecture and dissection of traits underpinning fodder quality and biofuel traits and their limited comparison with other related model crop species.
本综述的主要重点是讨论由于性状相似，利用 GWAS 研究饲料质量和生物燃料的现状。高粱是一种潜在的多用途作物，因其用途广泛而广受欢迎，可用于食品、饲料、生物量生产乙醇等。大量生物量的产生和复杂糖的遗传变异不仅是将高粱用作饲料以满足营养学家需求的主要动机，也是作为生物燃料生产的潜在候选物的主要动机。关于可以从生物燃料技术的发展中转移并应用于提高饲料质量，反之亦然的知识转移，鲜有研究报道。随着基因分型技术的最新进展，GWAS 已成为用于鉴定与表型相关的基因/基因组区域的主要工具之一。这些现代工具和技术加速了基因组辅助育种过程，提高了遗传增益的速度。因此，本迷你综述重点介绍了有关遗传结构的 GWAS 研究以及支撑饲料质量和生物燃料特性的性状的剖析，并与其他相关模式作物物种进行了有限的比较。
