The objective of this research is to contribute to the
improvement of tomato productivity in Mali. Tomatoes remain one of the most
widely grown vegetable crops in the world. It is the most consumed vegetable in
the world after potatoes. However, its production faces enormous difficulties
such as the extreme poverty of the soil, the low technicality of the producers,
the high pest pressure and the scarcity of high-performance varieties. Of
these, bacterial wilt is an important factor, as it causes a huge loss of
production on average if left unchecked. A study was carried out on the
evaluation of the resistance of five varieties of tomato (Anaya, Raja, Tingal,
Mona and Petomek) to bacterial wilt (Ralstonia solanacearum) in the
agro-climatic conditions of Katibougou. The experimental device used was the
Fisher block with three (03) repetitions to five (05) treatments. The analysis
of biometric observations shows that the Raja variety had the largest diameter
at the collar with 12.13 cm at the 60th day after transplanting, the highest
number of leaves at 40.1, it also gave the highest number of branches with 9.8
and also the greatest height of the plants with 82.5 cm. Regarding the
incidence of bacterial wilt, the Petomek variety (T5) had the highest
percentage with 73%, followed by the Anaya variety (T1) which had 70%. As for
the severity, a total of three (03) observations were made, the analysis of
variance showed a significant difference between the levels of variation, the
Petomek variety (T5) had the highest score with 85.9%, followed by the Anaya
variety (T1) which recorded 84.4% and finally the Tingal (T3) and Mona (T4)
varieties had the lowest scores 24.4%. In terms of yield, the Tingal variety
had the best yield with 45.83 t/ha, followed by the Mona variety with 39.46
t/ha. Finally, the Anaya and Petomek treatments gave the lowest yields with
21.66 t/ha and 20.55 t/ha, respectively.
