Abstract： Pigeonpea （Cajanus cajan） is the sixth largest edible beans globally with extensive usages. The characteristics of pigeonpea germplasm resources are closely related to the stress resistance due to the rich genetic diversity. This paper summarized the research progresses on genetic diversity， physiological and biochemical indices and mechanisms of stress resistance of global pigeonpea studies order to provide references for the future researches on stress resistance and pigeonpea breeding. The industrialization prospects of pigeonpea are also proposed here.

Keywords： pigeonpea; genetic diversity; stress-resistance; physiology and biochemistry indices
