Abstract

Global climate change and global warming, coupled with the growing population, have raised concerns about sustainable food supply and bioenergy demand. Sorghum [Sorghum bicolor (L.) Moench] ranks fifth among cereals produced worldwide; it is a C4 crop with a higher stress tolerance than other major cereals and has a wide range of uses, such as grains, forage, and biomass. Therefore, sorghum has attracted attention as a promising crop for achieving sustainable development goals (SDGs). In addition, sorghum is a suitable genetic model for C4 grasses because of its high morphological diversity and relatively small genome size compared to other C4 grasses. Although sorghum breeding and genetic studies have lagged compared to other crops such as rice and maize, recent advances in research have identified several genes and many quantitative trait loci (QTLs) that control important agronomic traits in sorghum. This review outlines traits and genetic information with a focus on morphogenetic aspects that may be useful in sorghum breeding for grain and biomass utilization.

高粱改良形态性状的遗传控制。
全球气候变化和全球变暖,加上人口增长,引发了人们对可持续粮食供应和生物能源需求的担忧。高粱[双色高粱]在世界谷物产量中排名第五;它是一种C4作物,比其他主要谷物具有更高的抗逆性,具有广泛的用途,如谷物,饲料和生物质。因此,高粱作为实现可持续发展目标(SDGs)的一种有前景的作物而备受关注。此外,与其他C4禾本科植物相比,高粱具有较高的形态多样性和相对较小的基因组大小,是C4禾本科植物适宜的遗传模型。尽管与水稻和玉米等其他作物相比,高粱的育种和遗传研究滞后,但最近的研究进展已经确定了高粱中控制重要农艺性状的几个基因和许多数量性状位点(qtl)。本文综述了高粱的性状和遗传信息,重点介绍了形态发生方面的信息,这些信息可能对高粱的粮食和生物质利用育种有用。

期刊介绍: Breeding Science is published by the Japanese Society of Breeding. Breeding Science publishes research papers, notes and reviews related to breeding. Research Papers are standard original articles. Notes report new cultivars, breeding lines, germplasms, genetic stocks, mapping populations, database, software, and techniques significant and useful for breeding. Reviews summarize recent and historical events related breeding. Manuscripts should be submitted by corresponding author. Corresponding author must have obtained permission from all authors prior to submission. Correspondence, proofs, and charges of excess page and color figures should be handled by the corresponding author.
