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
Health measures during the construction of the Panama Canal had died during the construction of the Panama Railway and over 22,000 during the French effort to build a canal. Many of these deaths were due to disease, particularly yellow fever and malaria. At several times, construction on the Panama Railway had actually halted due to the lack of healthy workers. The high rate of deaths among workers on the Panama Canal due to disease was the source of a great deal of controversy in the United States. Newspapers, such as "The Independent", frequently reported on the poor conditions workers in the Canal Zone experienced, including the rampant disease. Poultney
