A study looked at different types of dolichos beans to see how they vary genetically. They found that some traits like pod length, pod weight, and number of pods per plant have a lot of genetic variation. These traits are also passed down from parent to offspring and can be improved through selective breeding. Some specific types of beans were identified as having desirable traits like early flowering, long pods, and high pod yield. These beans with green, purple, or creamy-white pods could be used in future breeding programs to create even better varieties.
