Evaluation of the Resistance of Five Tomato Varieties to Bacterial Wilt (Ralstonia solanacearum) under the Agro-climatic Conditions of Katibougou | Chapter 8 | Microbiology and Biotechnology Research: An Overview Vol. 4

 

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.
