INTRODUCTION Proper specification of pigmentation in tissues such as flowers and seeds is essential for the survival of wild plants and is critical for market acceptance of crops. In the wild, pigmentation is vital for pollinator attraction, camouflage of seed to reduce herbivory, and promotion of seed dispersal.

Abstract Seed colors and color patterns are critical for the survival of wild plants and the consumer appeal of crops. In common bean, a major global staple, these patterns are also critical for determining market classes, yet the genetic and environmental control of many pigmentation patterns remains unresolved. In this study, we genetically mapped variation for three important seed pattern loci, T, Bip, and phbw, which co-segregated completely with PvTTG1, PvMYC1, and PvTT8, respectively.
