The invention relates to the technical field of
hybrid breeding, in particular to a wheat hybridization method for increasing the setting rate. The method comprises the steps that when wheat grows to a flower
bud differentiation period, a wheat growth
promoter is sprayed to male parents and female parents; after female parent ears are completely headed, flag leaves are stripped off, one third of each spikelet is
cut off, stamens are removed, a pistil growth
promoter is sprayed,
glassine bags are taken, the female parent ears are covered with the
glassine bags, test tubes containing water are fixed in the
glassine bags, male parent ears are
cut out to be placed in the test tubes which are fixed in the glassine bags and contain water when the selected male parents hybridized with the female parents grow to a flowering period, the glassine bags are shaken in a hybridizing
pollination period to complete natural
pollination between the male parents and the female parents, and after
pollination is completed, the glassine bags and the test tubes are taken down; when the pollinated female parents grow to a filling period, a filling period
regulator is sprayed. According to the method, the pollination method is combined with
nutrient supply of wheat in different periods, false hybridization is avoided, the
hybrid breeding efficiency is improved, and the setting rate and the yield are increased.
