Method for breeding and planting morning glory with high ornamental value, disease resistance and high yield

Abstract

The invention relates to a method for breeding and planting morning glory, and belongs to the technical field of plant breeding. By the method for breeding the morning glory with a high ornamental value, disease resistance and high yield provided by the invention, the obtained new variety of the morning glory has the characteristics of vigorous growth, excellent ornamental traits, large flowering number, long ornamental period, high heat resistance and disease resistance; after the strain is determined, pollen and affinity are further optimized, so that the seed yield of the new variety is high. By the method, disease-resistant and high-yield hanging morning glory without climbing property is bred; the variety type of the morning glory is increased; the species of ornamental horticultural plants are enriched; a hanging greening ornamental effect is enhanced.

Description

technical field

[0001] The invention relates to a breeding morning glory and a cultivation method thereof, belonging to the technical field of plant breeding. Background technique

[0002] Morning glory (Pharbitis nil (Linn.) Choisy) is an annual trailing winding herbaceous plant of the genus Petunia in the family Convolvulaceae. There are many horticultural varieties, among which the hanging morning glory is a new variety with ornamental value, with thin trailing stems. Length: 180-250cm, the whole plant is densely covered with short bristles. Alternate leaves, split leaves, flowers axillary, usually 1 to several flowers are born on the top of the peduncle, and the corolla is trumpet-shaped. The flowers are bright and beautiful. The capsule is spherical, the back of the cell is dehiscated after maturity, the seeds are black, brown or yellowish white, and the life span is very long. There are irregular yellow and white patches on the green leaves. The flowers are large, w...

Embodiment 1

[0045] Such as figure 1 As shown, the present embodiment selects and breeds disease-resistant, high-yield morning glory by the following methods:

[0046] 1. Selection of parental materials: in the seeding fields of large-flowered white pendant morning glory (K11-56) and purple (K11-53) climbing morning glory, the number of blooms is large and the rate of seed setting is high. No powdery mildew disease as the goal of single plant selection.

[0047] 2. These individual plants were selected in the same year, and each individual plant was self-crossed after marking, and F 1 generation seeds.

[0048] 3. In the two varieties of F 1 In the plant population after planting the generation seeds, continue to select individual plants with the goal of having more flowers, high seed setting rate, and no powdery mildew disease, and use the individual plants selected from K11-56 as the female parent, and use A(K11 -53) The selected single plant is used as the male parent for interspeci...

Embodiment 2

[0068] Such as figure 2 As shown, the present embodiment selects and breeds disease-resistant, high-yield morning glory by the following methods:

[0069] 1. Selection of parental materials: in the seeding field of large-flowered white hanging morning glory (K11-56) and pink (K11-54) climbing morning glory, the number of blooms is large and the rate of seed setting is high. , no powdery mildew disease as the target breeding single plant.

[0070] 2. These individual plants were selected in the same year, and each individual plant was self-crossed after marking, and F 1 generation seeds.

[0071] 3. In the two varieties of F 1 In the plant population after the planting of generation seeds, continue to select single plants with the goal of having more flowers, high seed setting rate, and no powdery mildew disease, and use the single plants selected from K11-56 as female parents, and respectively use B(K11 -54) The selected single plant is used as the male parent for intersp...
