In sub-Saharan Africa (SSA), maize (<i>Zea mays</i> L.) is both a cash crop and an important staple crop. However, <i>Striga</i> <i>hermonthica</i> infection constrains its production and productivity. A total of 159 hybrids from 21 international trials were evaluated under <i>Striga</i>-infested (STRINF) and <i>S</i>triga-non-infested (STRNON) conditions at Mokwa and Abuja, Nigeria, from 2010 to 2021. Generally, substantial progress has been achieved with a good level of repeatability estimates for the early maturing maize hybrid trials evaluated under STRINF and STRNON conditions. The results obtained in the study demonstrated that the breeding strategies adopted during the 12-year breeding period have been effective and that the potential of the trials in the exploration of the genetic potential of the hybrids for commercialization in the SSA for food security and poverty alleviation.

在撒哈拉以南非洲（SSA），玉米（Zea mays L.）既是经济作物，也是重要的主粮作物。然而，寄生杂草苏丹独脚金（Striga hermonthica）的侵染严重制约了玉米的生产与产量。本研究于2010年至2021年间，在尼日利亚莫夸与阿布贾两地设置试验，分别在独脚金侵染（STRINF）与无独脚金侵染（STRNON）两种条件下，对来自21项国际试验的共计159个玉米杂交种开展评估。总体而言，针对在STRINF与STRNON条件下开展的早熟玉米杂交种试验，其重复性评估值处于较高水平，本研究已取得实质性进展。研究结果表明，为期12年的育种周期中所采用的育种策略行之有效；同时此类试验具备挖掘杂交种遗传潜力的价值，可用于在撒哈拉以南非洲地区推广这些杂交种，以保障粮食安全并助力减贫事业。
