About Hybrids
Hybrids are the result of crossing 2 "fixed" (stable) parent lines. Hybrids are more vigorous than their parents, produce more fruit and are less susceptible to disease. All papaya are affected by climatic changes but when grown under stable conditions hybrids are very consistent in fruit shape and size. Hybrid seed for sale here is only the first cross of the parent lines, producing F1 hybrids. Hybrids cannot be successfully grown from seed collected from F1 fruit and will be inconsistent in shape, size and yield.
Bisexual papaya are affected by a condition known as carpellody or "cat-facing" and is caused by the fusing of the ovary and stamens during adverse weather conditions. This fruit is deformed and unmarketable. Carpellody is one of the reasons bisexual varieties are not normally grown in sub-tropical areas.
How much seed will I need?
With dioecious varieties growers generally plant 4 seedlings to the site, thinning sites to 1 male site to 10 female sites. Planting density varies between growers but on average is 750 sites to the acre, or 1850 to the hectare. The amount of seed required is 50 grams per acre or 125 grams per hectare.
With bisexual varieties growers generally plant 3 or 4 seedlings to the site, thinning to 1 bisexual tree per site. Some growers market the female fruit of the bisexual, although the flesh is not as thick. Seed required is 40 grams per acre or 100 grams per hectare.
