Panama disease when the seedling is aneuploid, results are not as good. Second-generation breeding using those new tetraploids as both parents has tended not to yield good results, because the first generation contains the Gros Michel triploid gene set intact (plus possibly useful features in the added fourth chromosome set), but in the second generation, the Gros Michel gene set has been broken up by meiosis. The Honduras Foundation for Agricultural Research cultivates several varieties of the Gros Michel. They have succeeded in producing a few seeds by hand-pollinating the flowers with pollen from diploid seeded bananas. Panama disease Panama disease is
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
