Brazil: Colombia receives banana varieties from Embrapa for testing

Published 2022년 3월 9일

Tridge summary

In vitro seedlings of banana varieties from Embrapa Mandioca e Fruticultura have been sent to Colombia for testing against race 4 Tropical of the fungus Fusarium oxysporum f. sp. cubense, the cause of Fusarium wilt. The varieties sent include BRS Princesa and BRS Platina, as well as improved banana diploids. The material will be quarantined for six months to confirm the absence of fungi, bacteria, viruses, and nematodes from the country of origin, and then tested for possible resistance to R4T in a greenhouse. This is part of a research agreement between Embrapa, AgroSavia, and Augura to develop resistant commercial cultivars of the fruit. Similar actions have also been taken with research institutions in Australia and Costa Rica.

In vitro seedlings of banana varieties, from Embrapa Mandioca e Fruticultura (Cruz das Almas, BA), are already in Colombia for testing in the presence of race 4 Tropical of the fungus Fusarium oxysporum f. sp. cubense (FOC R4T), responsible for Fusarium wilt, the most destructive disease of culture, still without definitive control and present in that country since 2019. In addition to the BRS Princesa (Apple type) and BRS Platina (Silver type) varieties, improved banana diploids were also sent – ancestral relatives of the current varieties – which are used in crosses to develop new commercial cultivars of the fruit. The material was planted in the quarantine station of the Instituto Agropecuario Colombiano (ICA), where it will remain for up to six months to confirm the absence of fungi, bacteria, viruses and nematodes existing in the country of origin. After this quarantine, they will go on to test in a greenhouse to check for possible resistance to R4T. “Colombia is a major ...
