This differs from natural selection in that, in nature, plants that do better in a particular environment will set seed and pass on the genes that made them successful in that environment. This process can be continued until the plant breeder feels the resulting plants are ready to be sold as a new variety. This is generally done by hybridization. We can raise different strains of food crops with desirable traits naturally as well as scientifically. Early farmers did this simply by saving seed from those plants they thought had good characteristics. Varieties resistant to these factors (stresses) can be improved to increase crop production. Crop diversity is an aspect of biodiversity important for food security. Taking care to prevent the biotic factors (diseases, insects and nematodes) andabiotic factors (drought, salinity, waterlogging, heat, cold and frost) that can affect the crop growth. The crop is selected by breeding for various useful characteristics; like disease resistance, response to fertilizers, product quality and high yields. Shorter maturity of the crops results in more economical variety. Plant breeders, on the other hand, select those plants that have qualities that are desired by humans: bigger fruit, higher yield, particular flavors (see section on domestication).
