A seed breeding points Technical line: Select a single plant → multiple plant → multiple plant → prolific plant → breeding plant → field plant. The annual generation of fine fields in accordance with stalks sturdy, more branches, white flowers, pod large grain, uniform growth, the same standard of maturity, select a considerable number of individual plants, and then entered into the row year after year, plant lines and seed Production, during the strengthening of technical management, especially in the flowering to podding period, must go to the strict removal of impurities, to ensure the purity of the seeds.
