Embodiment

[0041] Embodiment Phalaenopsis new variety breeding method

[0042] 1 material

[0043] The test material is a hybrid progeny population of the flower germplasm resource nursery of the Vegetable and Flower Research Institute of Shandong Academy of Agricultural Sciences. Male parent (♂): Phalaenopsis'31', tall plant type, deep purple-red large flowers, hidden lines, papery petals, main color purple-red lips, long beards on the lips (such as figure 1 ); female parent (♀): Phalaenopsis 'C27', short plant type, yellow medium-sized flowers, thick waxy petals, orange and white main colors of the lips, no beard on the lips (such as figure 2 ).

[0044] 2 methods

[0045] 1) material selection and processing: picking 115d Phalaenopsis hybrid fruit pods (such as image 3 ), washed with tap water, placed on an ultra-clean workbench and soaked with 75% alcohol for 10 minutes, then rinsed twice with sterile water, and placed in a stainless steel tray to dry;

[0046]2) Rapid aseptic...

Abstract

The invention discloses a detoxification, regeneration and rapid propagation method for butterfly orchid stem tips. According to the method, a repeated stem tip lift-off technique, an anti-browning technique, a virus inhibitor treatment technique and an alternate temperature-heat treatment technique are simultaneously combined, so that the content of toxin of tissue culture seedlings is effectively reduced, and the survival rate of the stem tips is increased. By virtue of the repeated stem tip lift-off technique, the situation that viruses at other parts of the plants spread towards stem tip meristems can be prevented; by cutting phyllopodium stem tip tissues, the content of toxin in the stem tips can be effectively decreased, and meanwhile, the survival rate of the tissue culture seedlings can be increased; by virtue of the pretreatment of the stem tips, the browning death rate of the stem tips can be remarkably decreased, and the survival rate of the stem tips can be increased; and meanwhile, the virus inhibitor treatment is combined with the alternate temperature-heat treatment, viruses CyMV and ORSV can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of flower breeding, and in particular relates to a method for breeding new varieties of Phalaenopsis. Background technique [0002] Phalaenopsis spp. is a plant of the genus Phalaenopsis in the family Orchidaceae. Its flower shape is similar to a butterfly, with bright colors and long flowering period. It is one of the most popular orchid species in my country. There are about 66 native species of Phalaenopsis, and Taiwan’s native resources are richer than those in China, and a large number of hybrid breeding work was carried out as early as the beginning of the 19th century. The varieties spread all over the world, creating huge economic benefits and greatly promoting the development of the Phalaenopsis industry. develop. Mainland China is the main producing area of ​​Phalaenopsis. However, due to the late start of breeding work and the lack of excellent Phalaenopsis parents, the germplasm resources mainly...
