Gene technology: aims in research and development
Agronomic traits
Disease resistance
Fungal resistance: with gene technological concepts, a resistance to the Black Sigatoka and Fusarium wilt has been produced in the banana. These fungae are pathogenic agents of the two most important banana diseases. With conventional breeding resources, an improved resistance is only achieved with great difficulty.
Viral resistance: to the Banana Bunchy Top Virus or the Banana Bract Mosaik Virus.
Bacterial resistance: in Uganda research is being done with gene technological modified bananas that show a resistance to Xanthomonas campestris. The bacterium activates a leaf wilt and causes profit cuts of up to 90 per cent.
Resistance against pests
Resistance to nematoden: for this purpose, cystatin genes are inserted into bananas. Cystatin inhibits active agents that nematodes produce in order to penetrate into the banana stalk. Thus, it prevents oviposition.
