Abstract :
Sorghum (Sorghum bicolor), grown in semiarid areas of Africa and Asia, is food source for millions
of people. This crop is subject to several constraints,
including Striga hermonthica, the most common parasitic
plant in sorghum fields in the Sahelian and Sudanian
zone. Striga causes significant damage to this crop. To
control this pest, a study entitled "Evaluation of West
African sorghum varieties for resistance to striga in the
Sudano-Sahelian zone of Mali" was carried out in the
research station of Samanko (ICRISAT). The objective of
the study was to identify striga resistant and/or tolerant
varieties compared to local controls and to describe the
evolution of the striga population according to the
development stage of these varieties. For this study, 126
varieties from several west African countries and two
local varieties as controls were used. Experimental design
was Alpha Lattice system. The following characteristics
were measured: plants vigor of sorghum, date of 50%
flowering for sorghum, number and vigor of striga at
different stages of sorghum development. Results showed,
that half of varieties had good to excellent vigor, 48% had
intermediate vigor and only 2% of varieties had very poor
vigor at emergence. Then striga resistants’ varieties were
identified, namely: Kouria, Dambima White, DORADO;
Lata//Ridb-8-9-1-1-bulk, SAMSORG 45, Framida,
Kapaala (ICSV 111), SAMSORG 6, SURENO,
NGUINTHE. The population of striga was less important
in the plots of these varieties i.e., 8 to 58 plants compared
to the resistant control Soumalemba in which plot the
population of striga was composed by 68 plants.
