Problems solved by technology

This method is not suitable for self-crossing of poppies, because the entire sepals of poppies wrap the petals at the bud stage, and when they bloom, the petals open and all the sepals fall off.

Embodiment Construction

[0016] When the poppies of white and other colors are used in the cross test, there is no white poppies in the offspring. This is because in the hybridization of different flower colors, the colored flowers are generally dominant and the white flowers are recessive. The following uses pure white poppies as an example to further illustrate the implementation process and effects of the present invention.

[0017] 1. On the day when the first top flower of a single white poppy plant blooms in early May of that year, select the single plant in the parent breeding field, insert a card next to each plant to mark the flower, and remove the top flower at the same time.

[0018] 2. The top 1 / 5 of the top flower buds of the first to fourth branches of each individual plant (bud length is about 30mm) are stapled with a stapler.

[0019] 3. On the second and third days, remove the flowers that have missed nails (the sepals of the flowers are off and the petals are fully opened as the criterion) ...

Abstract

The invention discloses a selfing method of a herbaceous-flower corn poppy, comprising the following steps of: when a first poppyhead of a single plant of a corn poppy blooms on the same day, selecting a single-seed color single plant in a parental propagating field, marking colors by inserting a card near each plant, and picking off the poppyhead at the same time, wherein the bud top of 1 / 5 of first-fourth first-branching poppyheads of each single plant is stapled by a laminater, a flower blooms after stapled by stapling nails on the second day and the third day, the bottom of a sepal cracks, the top of the flower is retained at the top end of a petal, and stamens and pistils are completely coated by the petals to realize self-fruition; ensuring the complete self-fruition of each color by picking off unstapled flowers; selecting the bud with the length of 25-35 mm according to varieties and blooming characteristics of the corn poppy every two days and stapling the bud of 1 / 5 by the laminater; and picking off the unstapled flowers at the same time. The selfing method is adopted to prevent flowers from blooming naturally in a blooming period, and can effectively block the introduction of external pollen and realize self-pollination fruition.

Description

Technical field [0001] The invention relates to a self-crossing method for poppies, belonging to the technical field of flower breeding. Background technique [0002] Papaver rhoeas (Papaver rhoeas) belongs to the family Papaveraceae, and belongs to the genus Papaver. It is a biennial herb. The height of the plant is 40-60 cm, the stems and branches are thin and the whole body is covered with short bristles. The leaves are alternate, irregularly pinnate and deeply lobed, lobes lanceolate, leaf margins with thick serrations, leaf blades are mainly found at the base of branches, flower buds are solitary at the top of long pedicels, bent and drooping when not in bloom, or the day before flowering The peduncle is erect on that day. The 4 petals overlap each other slightly to form a disc-shaped corolla with shallow wavy edges and a flower diameter of about 5-6 cm. The colors are rich, including white, pink, red, deep red, purple red, etc., as well as multiple colors. The entire co...
