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
Crop destruction can be usefully harvested by this means, such as sugar cane. "The Grapes of Wrath" by John Steinbeck tells about destruction of oranges, potatoes, pig carcasses and other agricultural products during the Great Depression. Crop destruction Crop destruction is the deliberate destruction of crops or agricultural products to render it useless for consumption or processing.

Related to crop destruction is alternate, low-price use of agricultural products. A large portion of
