豇豆属是一个大属，约有90种，分布于世界各地的温暖和热带地区。该属包括13个栽培种（表1），其中豇豆、绿豆和红豆是最重要的栽培种（表2）。也许是由于豇豆主要是发展中国家的作物，分子标记和基因组研究落后于其他主要作物。例如，已知基因组命名用于许多作物属中的物种，如大豆，但这些尚未建立用于豇豆属物种。近年来，在利用分子标记研究豇豆遗传资源、构建豇豆基因组图谱以及将分子标记与重要农艺性状相关联方面取得了很大进展。但2002年底分子标记在豇豆育种中的实际应用仍在计划中。在这一章中，我们回顾了最近的进展，利用分子标记在了解豇豆遗传资源，豇豆连锁图谱的发展，特别是在有关的农艺性状基因的位置，和转化系统。
The genus Vigna is a large genus with about 90 species distributed worldwide in warm and tropical regions. The genus includes 13 cultigens (Table1), of these cowpea, mungbean and azuki bean are the most important (Table2). Perhaps due to Vigna cultigens being mainly crops in the developing world, molecular marker and genomic studies have lagged behind those of other major crops. For example, genome designations are known for species in many crop genera, such as Glycine, but these have not been established for Vigna species. There has recently been considerable progress in using molecular markers to understand Vigna genetic resources and in developing genome maps and associating molecular markers to agronomically important traits in the Vigna cultigens. However, the actual use of molecular markers in Vigna breeding at the end of 2002 is still being planned. In this chapter we review recent progress in the use of molecular markers in understanding Vigna genetic resources, Vigna linkage map development, particularly in relation to the location of genes for agronomic traits, and transformation systems.
