The fresh fruits of 'Grande Naine' (Cavendish AAA- spp.) dominate the world market, especially in countries with a population in a situation of social vulnerability. However, Fusarium wilt, caused by the fungus f.
Banana breeding involves creating hybrids with varying ploidy levels (diploid, triploid, tetraploid) to enhance desirable traits and increase genetic diversity in bananas, focusing on resistance to diseases like yellow and black Sigatoka and Fusarium wilt.
Embrapa's Banana Genetic Breeding Program aims to cross improved diploids with commercial triploids to boost both genetic variability and agronomic performance.
A genetic diversity study using DNA markers identified key improved diploid genotypes for breeding, revealing significant genetic differences that can guide effective crossings to maintain beneficial traits in commercial banana varieties.
