Thread loop-knot type purple bell pepper selfing technology

Abstract

The invention discloses a thread loop-knot type purple bell pepper selfing technology and belongs to the technical field of plant breeding. The thread loop-knot type purple bell pepper selfing technology includes: firstly, selecting single selfing plants of purple bell peppers prior to labeling; secondly, selecting flowers about to bloom from the labeled single plants; thirdly, looping domestic white threads, enabling every loop at one end to sleeve a pedicel with slightly tightening and leaving every thread 2cm in length at the other end; fourthly, wrapping the flowers and the threads with sticky label paper, and pinching the upper end and the lower end of the sticky label paper; fifthly, harvesting fruit labeled by white loops in a physiological mature stage.

Description

technical field [0001] The invention discloses a thin-line double-knot type purple bell pepper selfing technology, which belongs to the technical field of plant breeding. First, select the self-bred individual plants of purple bell pepper and mark them; secondly, select the flowers that are about to open in the individual plants that have been marked; use the double single-knot method to tie the household white thin wire into a circle, and wrap the coil at one end on the pedicel, and close it slightly Tight, leave a 2cm long thin line at the other end; wrap the thin line and flowers with self-adhesive label paper and pinch the upper and lower ends tightly; harvest the fruits marked with white coils at the physiological maturity stage. Background technique [0002] Capsicum is a highly cross-pollinated plant, and its purification usually requires artificial pollination. There are many shortcomings in the above-mentioned method, and the one, pollination speed is slow. It tak...

There are many shortcomings in the above-mentioned method, the one, pollination speed is slow

It takes at least 20-30 seconds for operations such as rotating and poking flowers, picking pollen, dipping pollen on the stigma, and listing; second, pollination efficiency is low

Artificial pollination is used in April-May. For ox horn peppers, sheep horn peppers, thread peppers, screw peppers, Chaotian peppers, and thin-skinned peppers, the success rate can reach more than 80%. Once it enters May-June or even 6-7 month, the pollination efficiency is greatly reduced; and in 4-5 months, artificially pollinate sweet peppers, and the pollination rate is only 40-50%; the third is that it is easy to cause biological mixing.

Artificial pollination mostly uses dissecting needles or syringe needles as inoculation tools. When inoculating different capsicum inbred lines, the pollen of the previous inbred line is likely to remain in the front of the tool, and the pollination of the latter inbred line may easily lead to biological confusion or impure
