Problems solved by technology

Buds are individually bagged and isolated, which is time-consuming and labor-intensive
The method of wrapping cotton around buds requires that the cotton fibers be wrapped around the buds several times during operation to ensure that the buds are entangled so that the petals cannot be open

Embodiment 1

[0021] 1) Plant selection: During the flowering period, focus on the selection of the pepper's plant type, leaves, flowers, nodes and disease resistance, and eliminate the different plants that do not meet the standards;

[0022] 2) Preparation of blended solution: heat and stir in a water bath to dissolve, control the water temperature at 50°C, prepare a blended solution with a mass concentration of sodium alginate of 7% and sodium carboxymethyl cellulose with a mass concentration of 1% with deionized water, and cool It can be used after reaching room temperature, and the pH of the prepared blend solution is 7.0-7.3;

[0023] 3) Bud selection: select flower buds 10 hours before flowering;

[0024] 4) Flower bud treatment: lightly hold the flower bud to be treated with one hand, and the blending solution with the other hand, immerse the flower bud in the blending solution until the connection between the calyx and the flower stalk, and mark it with a color line;

[0025] 5) M...

Embodiment 2

[0026] Example 2: The temperature of the water bath is 55°C, the mass concentration of sodium alginate in the solution is 5%, and the mass concentration of sodium carboxymethylcellulose is 0.5%, and flower buds 6 hours before flowering are selected, and the others are the same as in Example 1.

Embodiment 3

[0027] Example 3: The temperature of the water bath in step 2) is 30°C, the mass concentration of sodium alginate in the solution is 10%, and the mass concentration of sodium carboxymethylcellulose is 2%, and flower buds are selected 8 hours before flowering, and the others are the same as in Example 1.

Abstract

Belonging to the technical field of plant breeding, the invention relates to a pepper inbred isolation method, which comprises the steps of: 1) plant selection: obsoleting substandard heterologous strains; 2) blend solution preparation: preparing a blend solution with a sodium alginate concentration of 5-10% and a carboxymethylcellulose sodium concentration of 0.5-2% with deionized water; 3) petal selection: selecting petals about 6-12h before flowering; 4) petal treatment: taking the petals to be treated on one hand lightly and taking the blend solution on the other hand, and soaking the petals in the blend solution till the joint of a calyx and a flower stalk, and making a mark with a color line; 5) management after treatment: identical with the routine field management method of pepperproduction. The pepper inbred isolation method of the invention isolates petals through a flexible film generated by the blend solution, and conducts geitonogamy to a gynoecium and a stamen of a sameflower. Being simple and rapid, the method of the invention can save the labor cost and has high?fruiting rate. Besides, the method in the invention causes no pollution to the environment and agricultural products, and can realize good application effect.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a pepper self-isolation method. Background technique [0002] Capsicum is a frequently cross-pollinated crop, mainly self-crossing, but there is a certain amount of natural hybridization, and the natural hybridization rate of different varieties is different. For sweet pepper varieties, the style is short, and the natural hybridization rate is below 5%; for pepper type varieties, the style is long, and the natural hybridization rate is higher than 20%. [0003] Peppers usually bloom from 6 to 8 o'clock in the morning. Generally, they bloom first and then crack. It takes about 3 days for each flower to wither. The viability of stamen pollen was highest on the day of flowering, followed by the day before flowering, and the weakest 2 days before flowering and 1 day after flowering. The active pollen ratios were 85%, 58%, 21.3% and 19%, respectively. The pistil h...
