ABSTRACT Fusarium wilt is a plant disease caused by Fusarium udum (Butler). It is a soil and seed borne fungus which causes significant yield losses in susceptible cultivars throughout the pigeonpea growing areas. Numerous control measures have been suggested to alleviate the problem but their success has still remained low due to prohibitive costs. Development of resistant pigeonpea varieties is sought as an alternative for control of the disease. However, the task of developing resistant pi...
