Evaluation of the 19 varieties and accessions of tomato against bacterial wilt in Bobo-Dioulasso, Burkina Faso. International Journal of Biological and Chemical Sciences, 14 (8) : 2870-2879.

Résumé : Bacterial wilt caused by Ralstonia solanacearum E. F. Smith is one of the most harmful phytobacteriosis in the world. The search for varieties resistant or tolerant to this disease is the main method of control. However, there is very little information on tomato accessions and varieties deemed resistant or tolerant to the disease in Burkina Faso, hence the resistance assessment of 19 tomato varieties and accessions in the field in order to improve the productivity of tomatoes in Burkina Faso. With respect to varietal screening, a completely randomized Fisher block was used and agromorphological parameters were evaluated. The evaluation has shown that CRA 66, F1 Platinum, NC72TR4-4, Hawaii 7996, BF-Okitsu and FBT4 are more resistant with respective incidences of 1.25%; 1.25; 1.47%; 2.50%; 2.95% and 4.37%; while L390 was the most sensitive (38.80%). In terms of production, F1 Platinum, F1 Mongal, FBT3 and FBT4 gave the best net yields of 25.85; 25.47; 20.6 and 20.34 tonnes.ha-1. On the other hand, some accessions (CRA66 and BF-Okitsu), which are less sensitive to the pathogen, gave derisory yields. In view of the results obtained, market gardeners in the city of Bobo-Dioulasso can be advised of INERA varieties FBT3 and FBT4 and the F1 Platinum and F1 Mongal hybrids for their good behavior in terms of resistance to the disease and/or of correct yield in infected soils.
