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 scouting planting date, planting rate (spacing), row width, tillage operations, crop yields, pesticide names, rates, application dates and who applied them, fertilizer and lime applications and rates, weather patterns, soil type, soil test records (N, P, K, percent organic matter, and pH), irrigation availability, major pest problems, and anything else that could make scouting more effective. This history is very important when assessing signs of crop injuries, because they are generally ambiguous since similar abnormalities can have unrelated causes. It is best to always be prepared when entering the field, as one never know what kind of issues one will find.
