Embodiment 1

[0065] Step 1: material selection

[0066] Select Dakota and Cherryred, and take Dakota as the female parent and Cherryred as the male parent.

[0067] Step 2: Manual pollination

[0068] During the flowering period from December to February, collect pollen when the anther sac of the cherry red spadix is ​​cracked for 1 to 2 days, and use a brush to impart it to the mucus secreted at the base of the spadix of the female parent. After pollination, bagging, labeling, indicating the parents, hybridization date and other information, and collecting as explants when the seeds mature to yellow;

[0069] After 4 months, the success rate of pollination was counted, reaching more than 90%.

[0070] Step 3: Aseptic sowing culture

[0071] Rinse the dirt on the surface of the yellow seeds with washing powder, then remove and clean the outer peel, soak in 75% alcohol for 35 seconds, then disinfect with 0.15% mercuric solution for 15 minutes, rinse with sterile water 6 times, filter pap...

Embodiment 2

[0083] Step 1: material selection

[0084] Choose Baby pear and Princess Amalia Brilliant, and use Baby pear as the female parent and Dream as the male parent.

[0085] Step 2: Manual pollination

[0086] Since the flowering period of Polaroid and Dream is different, the parent material of the male parent Dream is placed in an artificial climate chamber, in which the temperature is set at 16°C at night, the cultivation temperature is 28°C-32°C during the day, the light intensity is 2000lx, and the light duration is 12h / d; one plant is treated Month; pollen was collected when the anther sac of the dreamy spadix cracked for 1 to 2 days, and was transferred to the mucus secreted by the base of the spadix of the female parent Polaroid with a brush. After pollination, bagging, labeling, indicating the parents, hybridization date and other information, and collecting as explants when the seeds mature to yellow;

[0087] After 4 months, the success rate of pollination was counted, ...

Embodiment 3

[0101] Step 1: material selection

[0102] Select Pandola (Bandola) and Yunzhi (Yunzhi), and use Pandora as the female parent and Yunzhi as the male parent.

[0103] Step Two: Pollination

[0104] Because Pandora and Versicolor versicolor have different flowering periods, the parent material of Versicolor versicolor was placed in an artificial climate chamber, where the temperature was set at 18°C ​​at night, the cultivation temperature during the day was 28°C-32°C, the light intensity was 2000lx, and the light duration was 12h / d; the treatment was 45 days; The pollen was collected when the pollen sac of Versicolor versicolor red spadix cracked for 1 to 2 days, and was transferred to the mucus at the base of the spadix of the female parent Big Brother with a brush. After pollination, bagging, labeling, indicating the parents, hybridization date and other information, and collecting as explants when the seeds mature to yellow;

[0105] After 4 months, the success rate of poll...

Abstract

The invention provides a hybridization breeding and rapid propagation method of anthurium. The hybridization breeding and rapid propagation method sequentially comprises the following six steps: material selection, manual pollination, sterile seed sowing and culture, propagation culture, seedling strengthening and rooting culture and test-tube plantlet transplanting. With the adoption of the method provided by the invention, the hybridization breeding success rate of the anthurium can be improved, certain asynchronous flowering period problems of hybridized combination are solved and high-quality germchits are rapidly cultured; and the hybridization breeding and rapid propagation method has the advantages of less investment, high yield and like, and is applied to large-scale production and protection of germplasm resources of the anthurium.

Description

technical field [0001] The invention relates to plant breeding and propagation methods, in particular to an anthurium hybrid breeding and rapid propagation method. Background technique [0002] Anthurium adndraeanum is a tropical herbaceous flower of the genus Anthurium Schott in the Araceae family. Its flowers are unique and elegant, and spathes are beautiful and colorful, and they are widely distributed in Central and South America. There are about 19 genera or subgenuses of Anthurium in the world, with more than 1,000 native species, variants and hybrids, and it is one of the largest genera of Araceae. Anthurium has a very high ornamental value due to its unique spathe and extremely long flowering period. It is one of the most widely cultivated and sold pot-cut flowers in the world. At present, the annual consumption of anthurium in the world has exceeded 10 billion Renminbi was introduced into my country in the late 1980s and began to be widely planted; so far, China has...
