普通菜豆的起源,进化和遗传资源

普通菜豆是世界上重要豆科作物之一，据研究，普通菜豆起源于两个独立的多样性中心，并分别在这两个中心被驯化成栽培植物，然后才逐渐引入世界各地。在长期的驯化和栽培过程中，进化力促使普通菜豆在形态，生理和遗传特性等方面发生了较大的演变，从而形成了丰富的遗传资源。本文就上述的研究进展作一简要综述，并就今后普通菜豆遗传资源的评价和利用工作提出一些见解。

ORIGIN,EVOLUTION AND GENETIC RESOURCES OF THE COMMON BEAN

Common bean is one of the most important leguminous crops in the world. Studies indicated that common bean originated from two indepentent centers of diversit,and had respectively been domesticated and cultivated in the two centers before they were introduced to the rest of the world.During the long process of domestication and cultivation, evolutionary forces have brought about morphological, physiological and genctic changes in the common bean hence forming abundant genetic resources for this species. This article gives a brief review of the research progress on the above subjects and proposes future perspectives for the evaluation and utilization of the common bean genetic resources.
