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
Sugarcane grassy shoot disease in boiling water for some time is suggested as a precaution. Phytoplasma infection also spreads through insect vectors; it is therefore important to control them. Sugarcane grassy shoot disease Sugarcane grassy shoot disease (SCGS), caused by small, parasitic bacteria, contributes to losses of 5% to 20% in the main crop of sugarcane, and these losses are higher in the ratoon crop. A higher incidence of SCGS has been recorded in some parts of Southeast Asia and India, resulting in 100% loss in cane yield and sugar production. Sugarcane is a vegetatively propagated crop, so the pathogen is transmitted via seed
