Embodiment 1

[0032](1) Selection of hybrid parents: From August to September, the female flower (i.e., the female flower with aborted stamens) of the silver-leaved blue bell flower is used as the female parent, and the hermaphrodite flower (ie, the male and pistil) of the thin-leaved blue bell flower is used as the female parent. Normally developed hermaphrodite flower) as the male parent for artificial pollination.

[0033] (2) hybridization bagging: select plump, firm flower buds on the female flower plant of Silverleaf Bluebell, and bag it with a sulfuric acid paper bag; meanwhile, select full, firm flower buds of the hermaphrodite plant of Silverleaf Bluebell, Bag it with sulfuric acid paper bag;

[0034] (3) Hybrid pollination: 4 to 5 days after the buds of the female flowers of the bagged Silverleaf Bluebell flower open, the stigma cracks, the edges of the lobes begin to bend, the surface secretes mucus, and the petals also begin to bend back, and the When the flower buds of the bag...

Embodiment 2

[0039] (1) Selection of hybrid parents: in August-September, use the female flower (i.e. the female flower with aborted stamens) of S. spp. Normally developed hermaphrodite flower) as the male parent for artificial pollination.

[0040] (2) hybridization bagging: select the plump, firm flower buds on the female flower plant of S. spp. Bag it with sulfuric acid paper bag;

[0041] (3) Artificial pollination: 4 to 5 days after the buds of the female flowers of the bagged Blue Bell flower open, the stigma cracks, the edges of the lobes begin to bend, the surface secretes mucus, and the petals also begin to bend back, and when the bagging When the flower buds of the hermaphrodite flower are open and the stigma is located in the center of the flower tube in a spherical shape and covered with pollen, take the pollen and smear it on the stigma of the female flower of the bagged blue bell flower to ensure that the stigma is covered. Pollen, that is, to complete artificial pollinatio...

Abstract

The invention discloses a method for cultivating a new potted flower variety by using cyananthus argenteus and cyananthus delavayi. The method comprises the following steps of performing artificial pollination by taking a female flower of the cyananthus argenteus as a female parent and a bisexual flower of the cyananthus delavayi as a male parent, or taking a female flower of the cyananthus delavayi as the female parent and a bisexual flower of the cyananthus argenteus as the male parent, collecting F1 hybrid seeds, and sowing the F1 hybrid seeds for seedling culture and maintenance. According to the method disclosed by the invention, the new potted flower variety of the cyananthus suitable for potting is cultivated by utilizing cyananthus plants, namely, the cyananthus argenteus and the cyananthus delavayi, for the first time, and specific hybridization measures are provided; by adopting the method disclosed by the invention, on the basis of keeping the advantages (blue flowers) of an original parent, bad characters (branches are easy to break, plants are small and the like) of the original parent are changed, and the obtained plants are dense in plants, not easy to break in branches, large in flowers, greatly improved in ornamental value and high in transplanting survival rate.

Description

technical field [0001] The invention relates to the technical field of plant cross-breeding, in particular to a method for cultivating new varieties of potted flowers by using silver-leaved blue bells and thin-leaved blue bells. Background technique [0002] The new and unique characteristics of garden plants have always been pursued by the world. Blue garden plants are popular because of their elegant and unique colors and scarce germplasm resources. [1] . There are many rich blue flower plant resources in our country, but due to long-term scientific research and less investment, these precious resources can only bloom in the mountains and fields. In recent years, with the improvement of people's living standards and income, the home gardening industry has emerged and gradually grown [2] . However, what does not match the booming domestic gardening industry is the seriously lagging research and development level of flower resources in our country. In order to meet the ...
