SCREENING OF MUNG BEAN GENOTYPES [VIGNA RADIATA (L.) WILCZEK] FOR RESISTANCE TO MACROPHOMINA PHASEOLINA (TASSI) GOID

Mung bean is a legume widely cultivated in subtropical and tropical regions of the world. Its introduction in Burkina Faso is of great interest for the food and nutritional security of the population. However, the development of its cultivation could be hampered by a number of biotic constraints, including fungal diseases caused by Macrophomina phaseolina (Tassi) Goid. To this end, 23 mung bean genotypes were screened in greenhouse with the most pathogenic isolate of the M. phaseolina fungus. Classification of genotypes according to recorded severity scores revealed three categories namely moderately resistant, susceptible and highly susceptible genotypes. No genotype proved resistant to the Sahelian isolate of M. phaseolina. However, two genotypes, M14 and lM2 showed moderate resistance to the Sahelian isolate of M. phaseolina. The results of this study could help in mung bean productivity program in Burkina Faso et in in drought-prone regions in the world.
