The invention discloses a breeding method of scallion
breed with
stress resistance, which is carried out according to the following steps: breeding of male sterile lines and the maintenance lines, breeding of inbred lines,
reproduction of the male sterile line, the maintenance line and the inbred line, breeding of excellent
first generation of
hybrid, matching of hybridized combinations, repeatedtrials and
reproduction of good combinations, wherein, a male sterile line of common growth scallion is chosen as
receptor, a scallion with
cold resistance,
disease resistance, small stomatal aperture and tight scallion stalk inclusion is chosen as donor, backcross is carried out for a plurality of generations, selection is carried out in this way for 5 generations, thereby breeding the male sterile line and the maintenance line with
cold resistance, small stomatal aperture and tight scallion stalk inclusion; wild scallion and Shule scallion with
cold resistance,
drought resistance and
disease resistance are chosen as materials, self cross, separation and selection are carried out according to the line method for a plurality of generations, the best are selected and the worst are weeded out, the self cross selection is carried out for 5 generations, thereby breeding the inbred line with cold resistance,
drought resistance and
disease resistance. The dry scallion series hybrids bred inthe invention have the advantages of
drought resistance, cold resistance, disease resistance, high yield, excellent quality, are suitable for dry-cultivation, and have extremely strong
stress resistance.
