Common bean ( L.) is a major legume crop, serving as a main source of dietary protein and calories and generating income for many Tanzanians. It is produced in nearly all agro-ecological zones of Tanzania. However, the average yields are low (<1000 kg/ha), which is attributed to many factors including virus diseases. The most important viruses of common bean in Tanzania are (BCMV) and (BCMNV) but other viruses have also been reported. There has never been a review of common bean virus diseases in the country, and the lack of collated information makes their management difficult. Therefore, this review focuses on (1) occurrence of different viruses of common bean in Tanzania, (2) molecular characterization of these viruses, (3) detection tools for common bean viruses in Tanzania and (4) available options for managing virus diseases in the country. Literature and nucleotide sequence database searches revealed that common bean diseases are inadequately studied and that their causal viruses have not been adequately characterized at the molecular level in Tanzania. Increased awareness on common bean virus diseases in Tanzania is expected to result into informed development of strategies for management of the same and thus increased production, which in turn has implication on nutrition and income.
普通菜豆（Phaseolus vulgaris L.）是一种主要的豆类作物，是膳食蛋白质和热量的主要来源，为许多坦桑尼亚人带来收入。它在坦桑尼亚几乎所有的农业生态区都有种植。然而，平均产量较低（<1000公斤/公顷），这归因于包括病毒病在内的许多因素。坦桑尼亚普通菜豆最重要的病毒是菜豆普通花叶病毒（BCMV）和菜豆普通坏死花叶病毒（BCMNV），但也有其他病毒的报道。该国从未对普通菜豆病毒病进行过综述，缺乏整理后的信息使得对其管理变得困难。因此，本综述重点关注：（1）坦桑尼亚普通菜豆不同病毒的发生情况；（2）这些病毒的分子特征；（3）坦桑尼亚普通菜豆病毒的检测工具；（4）该国管理病毒病的可用选项。文献和核苷酸序列数据库搜索显示，坦桑尼亚对普通菜豆病害的研究不足，其致病病毒在分子水平上也没有得到充分表征。预计提高坦桑尼亚对普通菜豆病毒病的认识将有助于制定明智的管理策略，从而提高产量，进而对营养和收入产生影响。
