Abstract

Soybean is an essential protein and oilseed crop, but environmental factors, such as photoperiod and altitude, highly influence its growth. Poor adaptability of soybean cultivars may result in a significant decrease in seed yield due to disruption of flowering or maturity. It is, therefore, vital to select cultivars adapted to specific regions of the world. Global climate change, causing increasing temperature and associated water deficit stress, may further challenge sustainable soybean production worldwide. Therefore, it is necessary to understand genetic responses in soybeans induced by environmental variables. This review highlights previous research showing how several quantitative trait loci (QTLs) activated by photo-thermal responses affected soybean flowering. We discuss cytogenetic stocks, including chromosome segment substitution lines, and their role in introgressing novel genes from wild soybeans. A review of genes showing responses to various environmental variables that affect soybean adaptability is also ensued, with putative functions suggested. These include gene response regulation to temperature and heat stress, identified via genetic mapping, and emerged as tools for developing adapted soybean cultivars.

大豆(glycine Max l .)的遗传增强适应性和生产力的种质

大豆是一种重要的蛋白质和油料作物，但光周期和海拔等环境因素对其生长有很大影响。适应性差的大豆品种可能会因开花或成熟中断而导致种子产量显著下降。因此，选择适合世界特定地区的品种是至关重要的。全球气候变化导致气温升高和相关的缺水压力，可能进一步挑战全球大豆的可持续生产。因此，有必要了解环境变量对大豆遗传反应的影响。本文综述了光热响应激活的几个数量性状位点(qtl)对大豆开花的影响。我们讨论了细胞遗传资源，包括染色体片段代换系，以及它们在野生大豆新基因渗入中的作用。随后，对影响大豆适应性的各种环境变量的基因进行了综述，并提出了可能的功能。其中包括通过遗传作图确定的对温度和热胁迫的基因反应调节，并成为开发适应性大豆品种的工具。

期刊介绍： The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO). Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society. The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards. The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
