摘要:

高粱(Sorghum bicolor L. Moench)作为世界第五大粮食作物,在应对全球粮食短缺问题中发挥着重要作用。培育高产优质高粱品种已成为现代高粱育种的核心攻关方向。粒重是决定高粱产量的三大要素之一,通过遗传改良增加粒重已成为提高单产的重要途径。因此,加强高粱籽粒发育的形态生理、遗传机制研究及粒重基因资源发掘,对培育高产品种至关重要。籽粒的形成涉及一系列生理生化代谢网络的协同调控,是受多基因控制的复杂数量性状。本文概述了高粱籽粒发育的形态生理过程及粒重性状的遗传特点,总结了高粱粒重相关数量性状基因座(QTL)/基因的定位及克隆进展,并鉴定了水稻粒重基因在高粱中的同源基因,旨在为后续高粱粒重基因克隆、遗传改良和分子设计育种提供依据,推动高产育种从传统的“经验育种”向定向、高效的“精确育种”转变。

Abstract:

Sorghum (Sorghum bicolor L. Moench), as the fifth most important cereal crop worldwide, plays a significant role in addressing global food shortages. Breeding high-yield and high-quality sorghum varieties has become a core objective of modern sorghum breeding. Grain weight is one of the three major determinants of sorghum yield, and increasing grain weight through genetic improvement has become an important approach to enhancing yield per unit area. Therefore, strengthening research on the morphological and physiological processes of grain development, the genetic mechanisms underlying grain weight, and the exploration of grain weight gene resources is essential for breeding high-yielding varieties. Grain formation involves a series of coordinated physiological and biochemical metabolic networks and is a complex quantitative trait controlled by multiple genes. This paper reviews the morphological and physiological processes of sorghum grain development and the genetic characteristics of grain weight traits, summarizes the progress in mapping and cloning of quantitative trait loci (QTLs)/genes associated with sorghum grain weight, and identifies homologous genes of rice grain weight genes in sorghum. The aim is to provide a basis for future cloning of sorghum grain weight genes, genetic improvement, and molecular design breeding, thereby facilitating the transformation of high-yield breeding from traditional “experience-based breeding” to targeted and efficient “precision breeding”.

Key words: sorghum, grain weight, physiology, genetic analysis, gene mapping and cloning
