Researchers at Colorado State University have developed Shiny Black Pearl, a black bean with a shiny seed coat and resistance to Bean common mosaic virus. It is recognized as a Specialty Crop in the United States. This variety offers yields, seed size, and maturity like other commercial black beans while adding a unique shiny appearance for dry pack and processed products.
Shiny Black Pearl is unique because of its shiny seed coat; a trait shared only with the variety Shiny Crow. Most U.S. black beans have dulled, opaque seeds. The shiny coat is stable across environments and gives beans extra appeal for specialty markets. This trait also affects water uptake, which is important for canned and processed products. Shiny Black Pearl combines commercial reliability with marketable quality.
Shiny Black Pearl is an erect indeterminate black bean (Phaseolus vulgaris L.) that combines reliable performance with a distinctive shiny seed coat. It is resistant to Bean common mosaic virus, giving growers confidence in mid-season production and reducing potential crop losses. The shiny seed coat is controlled by a single dominant gene, Asper (Asp), which ensures the trait is stable across different environments. This trait not only makes the beans more visually appealing but also affects how they absorb water, a key factor for processing and canning.
Over three years of testing in Fort Collins, CO, Shiny Black Pearl showed water uptake like Shiny Crow but slower than opaque-seeded varieties like Midnight and Raven. This means processors can plan soaking and cooking times more consistently, especially for canned or value-added products. The variety also matches other commercial black beans in yield, seed size, and days to maturity, making it a practical choice for growers. Overall, Shiny Black Pearl provides a combination of high yield potential, marketable appearance, and processing suitability, making it ideal for both traditional and specialty markets.
