Seeds germinated by this process will be first generation hybrids of the male and female parents. Without intervention, trees of the same species are able to cross-pollinate when their bloom periods overlap, creating hybrid seeds. Name and email details are required.

This means it will flower regardless of light cycle, unlike photoperiodic strains. HYBRID Estimated Maturity: 85 days A very classy watermelon. Hybrid cucumbers have been produced by hand pollination, One of the earliest hybrids is known as “Skunk”. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species.
