Understanding the genetic control of Fusarium wilt resistance is crucial in pigeonpea breeding programme. This study aimed to study the gene action controlling Fusarium wilt resistance, yield and yield components and select promising crosses possessing resistance to Fusarium wilt along with important agronomic yield traits. Six lines were crossed with four testers in a line x tester mating design. For Fusarium wilt reaction, F₁’s progenies were evaluated in a sick field having inoculums of Fusarium wilt at one location for two seasons and in a pot as well. The F₁’s and parents were evaluated for yield and yield components at two locations for two seasons using a row-column design with two replications. Results indicated that parents and crosses had highly significantly difference for yield and important agronomic traits. General combining ability (GCA) effects of lines and testers were also significant. Specific combining ability (SCA) was also significant for some crosses. Non-additive gene action was more important than additive gene action except for days to maturity and plant height. Crosses ICEAP 00932 × TZA 2439 and ICEAP 00932 × TZA 197 displayed small effects of SCA for Fusarium wilt and large SCA for most of yield traits and should be used for integrated disease management.

了解木豆枯萎病抗性的遗传控制在木豆育种计划中至关重要。本研究旨在研究控制枯萎病抗性，产量和产量构成部分的基因作用，并选择对枯萎病具有抗性以及重要的农艺性状的有前途的杂交品种。六个生产线与四个测试仪在生产线x测试仪配对设计中交叉。对于镰刀菌枯萎反应，在一个病斑中对F ₁的后代进行了评估，该病菌在一个位置以及一个盆中在两个地点都有镰刀菌枯萎的接种物。F ₁使用两个重复的行列设计，在两个季节的两个位置评估了父母和父母的产量和产量组成。结果表明，亲本和杂交种在产量和重要农艺性状上有极高的差异。品系和测试人员的综合结合能力（GCA）效果也很重要。特定的结合能力（SCA）对于某些杂交也很重要。非累加性基因作用比累加性基因作用更重要，除了成熟天数和株高。杂交后代ICEAP 00932×TZA 2439和ICEAP 00932×TZA 197对枯萎病显示出较小的SCA效应，而对于大多数产量性状显示出较大的SCA，应用于综合病害管理。
