美国农业研究局的研究者与华盛顿州大学和爱德荷州大学合作，已培育出三个籽粒更大、颜色更鲜艳、产量更高和更抗病的干豌豆品种，它们的名称分别是Joel、Fation和Shawnee。Joel是个绿色的干豌豆，抗白粉病，产量较高，籽粒比目前种植的品种籽粒大得多。在煮熟后籽粒还保持暗绿 In collaboration with the University of Washington and the University of Idaho, researchers at the Bureau of Agricultural Research have developed three varieties of dry pea that are larger in grain size, more vivid in color, yield higher and more resistant to disease, and are named Joel Fation and Shawnee. Joel is a green dry pea that is resistant to powdery mildew and has a higher yield of kernels than the currently grown kernels. The grains also remain dark green after cooking
