Bacterial Wilt of Groundnut: Control with Emphasis on Host Plant ResistanceV KMehanauthorDMcDonaldauthorPSubrahmanyamauthorBACTERIAL wilt caused by P~eudomonas~o lanaceorum is the only important bacterial disease of groundnut. It is a rerlous problem in major groundnut-producing are= of Indonesia (Schuarr and Hanlcy 1927; Machmud, thele Proceeding,), in southern China (Darong et at. 1981). and in restricted areas of Africa (Simbwa-Bunnya 1972). The di~iws a potential threat to groundnut prcb duction in several other pans of the uorld, apccially in warm humid areas. Effectlve control measurn arc to use sui~able crpp rotations and to grow wilt-resistant groundnut ~ultivars (Schwarz and Hartley 1930; Porter et al. 1982). Bmderl have produced bacterial wilt-resistant groundnut cultivars in several parts of the world (Schwarz and Hartley 1926; Darong et al. 1981). Several scrrcning/inoculation techniques hare been used to identify sources of resistance (Darong el at. 1981; Winstead and Kelman 1952), but the wide range of variability in the pathogen populations complicata wilt resistance breeding.Groundnut1985Conference or Workshop Item
