Resistance Assessment of Tomato (Solanum Lycopersicum L.) and Gboma (Solanum Macrocarpon L.) Cultivars Against Bacterial Wilt Caused by Ralstonia Solanacearum in Benin

Tomato Hybrid and Local Varieties Screened for Resistance to Bacterial Wilt Caused by <i>Ralstonia solanacearum</i> under Screen House and Field Conditions

“…The variety Hawaii 7997 was obtained from the World Vegetable Center, Cotonou. The local variety Tounvi was used as the known susceptible control [6] while PADMA [16] and Hawaii 7997 [22] were considered as resistant controls.…”

“…The detection of bacteria in inoculated but not wilted plants was performed at 28 days after transplanting in screen house and field experiment. The fingerprinting technique described by [16] was used. Ten-cm length stems of unwilted plants were cut from the collar.…”

“…The most effective and worldwide reported management method is the use of resistant genes. According to Oussou et al [16], disease management through the introduction of resistant varieties is the appropriate method that is less expensive for farmers and not aggressive to the environment. Thus, several resistant varieties have been selected worldwide.…”

“…Research by Oussou et al [16], when evaluating the behaviour of nine tomato varieties to bacterial wilt, identified two varieties, PADMA and Platinum as resistant. These two resistant varieties are not sufficient, especially for good production of tomato in contaminated areas.…”

“…Of the 36 tomato varieties grown in Benin [21], the status of only eight of them to bacterial wilt was known. The behavior of Be-nin local tomato varieties has not been reported except the susceptibility of variety Tounvi [6] [7] [16]. To increase the number of tomato resistant genes, this study aims to evaluate the behavior of other hybrid and local tomato cultivated varieties in Benin.…”
