The invention provides an oat feeding hybridization method for increasing the maturing rate and application thereof, and belongs to the technical field of oat hybridization, and the oat feeding hybridization method comprises the following steps: S1, selecting oats of different varieties or different
germplasm resources as female parents and male parents; s2, performing
castration treatment on a first floret of a base part of a non-self-pollinated spikelet of the female parent in the heading period of the oat, and performing bagging treatment; s3, taking out anther or
pollen which is just cracked from the male parent, and pollinating the anther or
pollen to stigmas of the female parent; s4, bagging the pollinated female parent until the pollinated spikelet grows seeds; according to the method, the uppermost spikelet which is subjected to flower closing
pollination, the lowermost tender spikelet and other florets in the spikelet are removed, and only the first florets at the base part are reserved for
pollination, so that the
nutrition supply of the pollinated florets is improved; the method comprises the following steps: taking out faint yellow, namely, just cracked anther or
pollen from male parent spikelets, pushing aside inner hulls, and feeding the anther or pollen to stigmas of female parents to simulate that fresh anther in a
natural environment is scattered to the stigmas, so as to increase the
pollination maturing rate.
