Common bean (Phaseolus vulgaris L.) is produced in eastern Hararghe both under sole crop and intercrop systems mainly from farm save seeds. Limited information is available on the influence of plant population density on seed quality of the crop Therefore; this study was conducted at Haramaya University research field to assess the influence of plant population on seed quality of common bean. The treatments were arranged in factorial combination of three improved varieties (Haramaya, Dursitu and Fadis) and three plant populations (320000, 180000 and 115200 ha-1) and laid out in RCBD with three Replications in 2017. The seed quality test in the laboratory was conducted in completely randomized design (CRD) with four replications. Plant population had significant effect on seedling shoot length, dead seeds, seedling vigor index I and II. Moreover, one or more of the possible two factors interactions significantly influenced  Seed quality parameters except speed of germination, vigor index I, abnormal seedlings, hard and fresh ungerminated seeds. The seed quality of Haramaya was exceeded by Fadis variety. Generally, the research findings suggested that the importance of using optimum plant population and high yielding variety to increase the quality seed produce and the productivity of the crop in the study area.
