The invention discloses a thread-guiding-type pepper
selfing fruit marking method and belongs to the technical field of
plant breeding. The thread-guiding-type pepper
selfing fruit marking method comprises the following steps: firstly selecting
selfing single plants, and marking by hanging a tag; secondly, selecting flowers about to bloom in the selected selfing single plants; threading a filament into a hand
sewing needle with a certain specification (0.2-0.4mm), and tieing a knot at one end close to a needle hole; threading a guiding thread of the hand
sewing needle through a
pedicel part of each flower to be bloomed; leaving the
tail end, about 2-3cm long, of the filament into the
pedicel part as a marker of a selfing
pollination flower; manually pollinating the marked flowers; and harvesting fruits with filament markers in the
pedicel parts in a physiological mature period.
