Brazil: Embrapa sends banana varieties for testing in Colombia

Published 2022년 12월 15일

Tridge summary

The article highlights a significant development in the fight against Fusarium race 4, a highly destructive disease affecting banana crops, with the shipment of banana genotypes from Embrapa Mandioca e Fruticultura to Colombia for testing. This second batch of genotypes includes improved diploids and new Prata-type banana hybrids, as well as somaclonal variants of the Cavendish and Prata types, all potentially resistant to Fusarium race 1 and subtropical 4, and notably, tropical race 4. This research is a critical step towards identifying banana varieties with resistance to the disease, which has been present in Colombia since 2019, and could protect Brazilian banana plantations. The research involves a collaboration between Embrapa, AgroSavia, and Augura, building on Embrapa's efforts in genetic improvement and disease management.

On the 12th, the second batch of banana genotypes sent by Embrapa Mandioca e Fruticultura arrived in Colombia for tests on resistance to tropical Fusarium race 4, the most destructive disease of the crop, still without definitive control and present in that country since 2019. Improved diploids – ancestral relatives of current banana varieties – and three new Prata-type banana hybrids were sent, including one that has stood out in the north of Minas Gerais and could be launched in 2024, and somaclonal variants of the Cavendish and Prata types, resistant to Fusarium race 1 and subtropical 4, which will also be evaluated for possible resistance to tropical race 4 of the fungus. There are 10 Cavendish and 6 Prata somaclones, obtained in tissue culture work by Embrapa, using the Grande Naine and Prata-Anã cultivars. These somaclones are currently undergoing agronomic evaluation in Vale do Ribeira (SP), Guanambi (BA) and Cruz das Almas (BA). New experiments will be installed in the ...
