Problems solved by technology

The disadvantage of this method is that the plastic plate has a certain weight. On the one hand, it will tighten the receptacle, which will cause obstacles to the receptacle’s transmission of nutrients and affect the normal growth of the fruit; The receptacle is torn off, resulting in pollination failure, and the capsicum selfing fruit cannot be obtained; in addition, the method of listing and locating selfing flowers also requires more labor and listing time, which reduces pollination efficiency

Embodiment

[0019] 1) Select an excellent individual plant: at the flowering stage, select an excellent intense purple pepper 7036 individual plant according to the breeding objective, and hang a white plastic plate on the main branch to mark it;

[0020] 2) Selected flowers: 5 flowers that are about to open within 12 hours of a single marked plant are selected;

[0021] 3) Making thread-leading equipment: cut off the front end of the needle hole of a 0.4mm sewing needle to form a semi-concave structure, and cut off the tip of the other end at the same time;

[0022] 4) Thin thread passing through the receptacle: put the thin thread into the semi-concave hole, and the thin thread and the semi-concave structure penetrate into the receptacle of the flower that is about to bloom;

[0023] 5) Leave the receptacle for the thin thread: leave the end of the thin thread about 2 cm in the receptacle as a mark for self-pollination flowers;

[0024] 6) Artificial self-pollination: Artificial self-p...

Abstract

The invention discloses a method for quickly positioning a selfing fruit of pepper, and belongs to the technical field of plant breeding. The method comprises the following steps: firstly, selecting a selfing single plant, and marking the single plant; secondly, selecting a flower to bloom in the marked single plant within 12h; thirdly, cutting off the front end of a needle hole of a hand sewing needle with a certain specification of 0.2-0.4mm to form a semi-concave structure, and cutting off a needle tip of the other end; fourthly, threading a thin thread into a semi-concave hole, and threading the thin thread and the semi-concave structure into a receptacle part of the flower to bloom within 12h; fifthly, cutting off a section of the thin thread which is about 2-3cm long, wherein the section of thin thread serves as a mark of a selfing pollination flower in the receptacle; sixthly, manually pollinating the marked flower; seventhly, harvesting a fruit marked by the thin thread in the receptacle in a physiological maturity period.

Description

technical field [0001] A method for rapidly locating self-fertilized fruits of peppers, belonging to the field of plant breeding, more specifically, a method for combining selected individual plants, selected flowers, making lead-in tools, lead-in tools to pull thin wires through the receptacle, leave the thin wires in the receptacle, and artificially Self-pollination, harvesting of physiologically mature fruits, etc., achieve the purpose of quickly locating self-fertilization fruits. Background technique [0002] Capsicum is a highly cross-pollinated plant, and its purification usually requires artificial self-pollination. Before artificial self-pollination, it is necessary to mark the flowers that are about to be pollinated. The method of listing is often used, that is, a thin line with a small plastic card is inserted into the receptacle. The disadvantage of this method is that the plastic plate has a certain weight. On the one hand, it will tighten the receptacle, which...
