Striga hermonthica, causes up to 100% yield loss in maize production in Sub‐Saharan Africa. Developing Striga‐resistant maize cultivars could be a major component of integrated Striga management strategies. This paper presents a comprehensive overview of maize breeding activities related to Striga resistance and its management. Scientific surveys have revealed that conventional breeding strategies have been used more than molecular breeding strategies in maize improvement for Striga resistance. Striga resistance genes are still under study in the International Institute for Tropical Agriculture (IITA) maize breeding programme. There is also a need to discover QTL and molecular markers associated with such genes to improve Striga resistance in maize. Marker Assistance Breeding is expected to increase maize breeding efficiency with complex traits such as resistance towards Striga because of the complex nature of the host‐parasite relationship and its intersection with other environmental factors. Conventional alongside molecular tools and technical controls are promising methods to effectively assess Striga in Sub‐Saharan Africa.

玉米(Zea mays)抗独脚金育种:撒哈拉以南非洲地区的过去、现在和前景

黑独脚金 (Striga Hermonthica ) 导致撒哈拉以南非洲地区的玉米产量损失高达 100%。开发抗独脚金玉米品种可能是独脚金综合管理策略的一个主要组成部分。本文全面概述了与独脚金抗性相关的玉米育种活动及其管理。科学研究表明,在玉米独脚金抗性改良中,传统育种策略比分子育种策略使用更多。国际热带农业研究所 (IITA) 玉米育种计划仍在研究独脚金抗性基因。还需要发现与此类基因相关的 QTL 和分子标记,以提高玉米的独脚金抗性。由于宿主-寄生虫关系的复杂性及其与其他环境因素的交叉,标记辅助育种有望提高具有复杂性状(例如对独脚金的抗性)的玉米育种效率。传统的分子工具和技术控制是有效评估撒哈拉以南非洲地区 Striga 的有前途的方法。
