Abstract
Banana production is severely affected by bacterial diseases jeopardizing
the food security of millions of inhabitants in countries where farmers
depend upon banana as staple food. Bacterial diseases like Xanthomonas
wilt, Moko, blood, and Bugtok are the most important diseases threatening
banana cultivation in several tropical and subtropical countries. Genetic
improvement of banana through classical breeding is diffi cult due to the
lack of resistant germplasm, sterile nature, and long generation time.
Transgenic technology can complement classical breeding for developing
bacterial disease-resistant varieties. Some success has been achieved for
developing host plant resistance in order to control banana Xanthomonas
wilt (BXW) disease. Currently, the transgenic bananas expressing either
sweet pepper Pfl p or Hrap gene are under evaluation for resistance to
Xanthomonas wilt disease in fi eld trials in Uganda. Management of bacterial
diseases through cultural practices like removal of male buds and use
of pathogen-free seed material and disinfected cutting tools can contain
outbreak of diseases although these are not absolute solutions for control
of bacterial diseases. In this chapter, we have discussed various management
practices as well as existing transgenic technologies to control bacterial
diseases of banana.
