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
Catch crop Catch crop In agriculture, a catch crop is a fast-growing crop that is grown between successive plantings of a main crop. For example, radishes that mature from seed in 25–30 days can be grown between rows of most vegetables, and harvested long before the main crop matures. Or, a catch crop can be planted between the spring harvest and fall planting of some crops. Catch cropping is a type of succession planting. It makes more efficient use of growing space. Catch crops are also crops that are sown to prevent minerals being flushed away from the soil: crops such as
