Saving seed
Seed saving for Bianco Di Trieste Select several healthy, true-to-type plants so the saved lot represents the variety rather than one unusually early or large individual. Squash and gourds are insect-pollinated and cross readily with other varieties of the same species. Confirm the species identified for this crop, then isolate by distance or controlled hand pollination. Mark seed fruit and let it reach full biological maturity; summer squash must become large and hard, winter squash must develop full rind color, and luffa or hard-shell gourds must mature well beyond the edible stage. Cure sound fruit before extraction when the crop benefits from curing. Remove, wash, and dry seed to a hard, storage-ready condition. Maintain several representative plants and record species, population, isolation, fruit selection, curing, cleaning, and test date.
