杜邦先锋宣布其 2015 年高粱杂交种产品系列，包括增加三种新杂交种。
这些杂交种为高粱种植者提供了强大的产量潜力、改进的农艺性能、广泛的防御特性包以及对灌溉和旱地土地的适应性。即将到来的季节的新混合动力车包括：
- Pioneer® hybrid 83P56 – a medium full-grain sorghum hybrid available in south and central Texas. The product provides improved standability with excellent root and stalk strength, in addition to above-average head exertion and a defensive trait package that fights pests such as downy mildew and sugarcane aphid.
- Pioneer® hybrid 83P73 – a new grain sorghum hybrid with excellent yield potential, adapted for both irrigated and dryland acres in south and central Texas. It has good defensive agronomic traits and brings improved harvest standability into the current sorghum lineup.
- Pioneer® hybrid 84P72 – provides strong yield potential and above-average stalks with acceptable root lodging resistance for its maturity, and is available in the High Plains regions of Kansas, Missouri and Nebraska. This hybrid has demonstrated strong drought tolerance, above-average cold emergence and good tolerance to fusarium rot.
先锋表示，它已投入大量资源进行研究，以不断改进美国和世界各地的高粱杂交品种。目前的研究项目包括研究非分蘖或低分蘖的杂交种、减少应激引起的倒伏的精确表型分析，以及疾病管理。这些试验在堪萨斯州曼哈顿的三个区域高粱研究中心进行；得克萨斯州普莱恩维尤；和德克萨斯州的塔夫脱。每个中心都位于可以评估重要疾病、昆虫或气候条件的环境中。在全球范围内，测试在四个国家的 60 个地点的 100,000 多个产量地块中进行。
