The hairy vetch (Vicia villosa Roth) cultivars ‘Purple Bounty’ (Reg. no. CV‐12, PI 648342) and ‘Purple Prosperity’ (Reg. no. CV‐11, PI 654047) were released in 2007 and 2008, respectively, by the USDA–ARS in collaboration with the Rodale Institute and the agricultural experiment stations of Pennsylvania State University and Cornell University. Hairy vetch is a commonly used annual legume cover crop grown for its cold tolerance, fast growth, large biomass production, and ability to fix N₂. However, this species has not been selected for the traits needed to optimize its use as a cover crop. Our breeding program focused on developing a cultivar that was both early flowering and had adequate winter survival and therefore adapted to mechanical termination in organic no‐till production in the U.S. Northeast and Mid‐Atlantic. Purple Bounty and Purple Prosperity were developed between 1998 and 2005 using recurrent selection at nurseries in Beltsville and Keedysville, MD. In 2005–2006, selections were evaluated against commercial checks for flowering time in Maryland and Pennsylvania, and in the 2006–2007 and 2007–2008 seasons they were evaluated in 10 locations (12 total site‐years) across the United States for winter survival. Purple Bounty and Purple Prosperity both flowered earlier than the commercial material against which they were tested (significance depended on the date and site); Purple Bounty was the earlier flowering of the two cultivars. Purple Bounty and Purple Prosperity also had equivalent or improved winter survival compared with ‘AU Early Cover’, an early‐maturing cultivar developed in the southern United States, at all test locations. Purple Prosperity is no longer commercially available, but Purple Bounty is currently licensed and distributed by Allied Seed (Nampa, ID).

注册“紫色赏金”和“紫色繁荣”毛hair子

紫etch（Vicia villosa Roth）品种'Purple Bounty'（Reg。no。CV-12，PI 648342）和'Purple Prosperity'（Reg。no。CV-11，PI 654047）分别于2007年和2008年发布。由USDA–ARS与Rodale研究所以及宾夕法尼亚州立大学和康奈尔大学的农业实验站合作。毛etch子是一种常用的一年生豆科植物，由于其耐寒性，快速生长，大量生物量生产和固定N _2的能力而种植。然而，尚未选择该物种以优化其作为掩盖作物的使用所需的性状。我们的育种计划着重于开发一个既能早开花又能在冬季生存的品种，因此适合在美国东北部和大西洋中部进行有机免耕生产的机械终止。“紫色赏金”和“紫色繁荣”是在1998年至2005年之间通过在贝尔茨维尔和马里兰州基迪斯维尔的托儿所反复进行选育而开发的。在2005–2006年，针对商业选择对马里兰州和宾夕法尼亚州的开花时间进行了评估，并在2006–2007年和2007–2008季节中，在美国的10个地点（总站点年-12年）对它们的冬季生存情况进行了评估。 。Purple Bounty和Purple Prosperity的花期都早于对其进行测试的商业材料（重要性取决于日期和地点）；紫色赏金是两个品种的较早开花。与“ AU Early Cover”（美国南部在所有测试地点开发的早熟品种）相比，Purple Bounty和Purple Prosperity的冬季存活率也相同或更高。Purple Prosperity不再可以从市场上买到，但是Purple Bounty目前已获得Alleded Seed（ID，Nampa）的许可和分发。在美国南部的所有测试地点开发的一种早熟品种。Purple Prosperity不再可以从市场上买到，但是Purple Bounty目前已获得Alleded Seed（ID，Nampa）的许可和分发。在美国南部的所有测试地点开发的一种早熟品种。Purple Prosperity不再可以从市场上买到，但是Purple Bounty目前已获得Alleded Seed（ID，Nampa）的许可和分发。
