Embodiment

[0026] 1) Select excellent individual plants: at the flowering stage, select excellent individual plants according to the breeding objectives, and mark them with pink plastic ropes;

[0027] 2) Capsule shell preparation: Separate the shell cap and shell body of the pre-purchased 0#, 1# and 2# bright yellow hollow hard capsule shells, and place them separately according to the size, so that they can be quickly taken according to the size of the bud during operation;

[0028] 3) Bud selection: select the big flower buds that are expected to open the next day;

[0029] 4) Flower bud treatment: gently hold the flower bud to be treated in one hand, and the capsule shell matching the size of the flower bud in the other hand, and gently cover the flower bud so that the lower opening of the capsule shell crosses the widest part of the flower bud, and use a marking pen to mark on the flower stalk. good mark;

[0030] 5) Management after treatment: the same as the conventional field ma...

Abstract

The invention belongs to the technical field of plant breeding, and in particular relates to a single flower selfing isolation method for small chili. The method comprises the following steps: (1) selecting an excellent single plant, namely in the flowering period, selecting the excellent single plant according to a breeding objective, and marking; (2) preparing a capsule shell, namely separating a shell cap from a shell body of a hollow hard capsule shell; (3) selecting a flower bud, namely selecting a large flower bud which is expected to bloom in the next day; (4) treating the flower bud, namely holding the flower bud to be treated by one hand, holding the capsule shell, which is matched with the flower bud in size, by the other hand, slightly sleeving the flower bud with the lower opening of the capsule shell over the widest part of the flower bud, and marking a flower stalk; (5) managing after the treatment in a method which is the same as a conventional field management method for the production of small chili. The capsule shell used in the method is low in cost and does not hurt the flower bud and the flower stalk when being used, the operation is convenient and easy, and the work efficiency is high; moreover, the capsule shell with certain elasticity and permeability does not influence the cracking of anther and pollination, and thus the selfing setting rate of the small chili is high.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a single-flower self-isolation method for chili peppers. Background technique [0002] Small peppers generally bloom first and then split, and each flower takes about 3 days from opening to withering. The pollen viability of stamens was the highest on the day of flowering, followed by 1 day before flowering, and the weakest 2 days before flowering and 1 day after flowering. The proportions of active pollen were 85%, 58%, 21.3% and 19%, respectively. The pistil has the ability to fertilize 2 days before flowering, but it is the strongest on the day of flowering, followed by 1 day before flowering. The pollination and fruit setting rates of 2 days before flowering, 1 day before flowering and the day of flowering were 21.4%, 57.1% and 71.4% respectively, and the fertilization ability of pistils was obviously weakened or lost 2-3 days after flowering. 2-4h after ...
