Panama disease in stress-tolerance, yield, or other beneficial traits necessary for commercial varieties. Nevertheless, these efforts are leading to the best control measure for Panama disease of banana. Recently, an R gene (RGA2) was transformed into Cavendish bananas which confers disease resistance to Fusarium wilt tropical race 4. This is the first case of successful resistance in the field and is a promising step towards preventing the loss of the Cavendish cultivars that are a huge portion of banana export production and subsistence of many communities. One major impediment to breeding bananas is polyploidy; Gros Michel and Cavendish bananas are triploid and
Cover crop Cover crop A cover crop is a crop planted primarily to manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an "agroecosystem" (Lu et al. 2000), an ecological system managed and largely shaped by humans across a range of intensities to produce food, feed, or fiber. Cover crops are an off season crop planted after harvest of the cash crop. The cover crop will grow up to, or into, the winter and may have to be terminated in the spring so as not to interfere with planting the cash crop. Cover crops are of
