A kind of Phalaenopsis pollen preservation and breeding method

Abstract

The invention discloses a butterfly orchid pollen storage and breeding method. A cap, a pollen load stem and a sticky tray of a butterfly orchid pollen are taken off, adhered in a pollen collecting box through the adhesiveness of the sticky tray, marked, and classified and stored according to the different varieties, can be used on the same day, can be stored for 2 months if being refrigerated ina refrigerator, and can be stored for months if stored at minus 20 DEG C. The flowering of a hybridized seedling is induced when the seedling is 2.5 inches on the field cultivation stage, the good-inflorescence seedling with flower color meeting the breeding objective is chosen to rapidly propagate, and the breeding time of the seedling is shortened by 5 months. The small test seedling obtained after rapid propagation is planted in a greenhouse, the flower forcing is started after the small seedling is planted to 1.7 inches and the moderate seedling is planted to 2.8 inches, the specificity, the consistency and the stability are tested after the flowering, the time of about 5 months is also shortened, and the whole flow shortens the breeding time of a new variety of the butterfly orchid.

Description

technical field [0001] The invention relates to a method for preserving and breeding phalaenopsis pollen, belonging to the technical field of flower breeding. Background technique [0002] Phalaenopsis orchid has a long flowering period, rich and colorful flowers, flying like butterflies, and is known as the "queen" of tropical orchids. It is loved by people all over the world and has become one of the most important potted flowers in the world. my country is one of the origins of Phalaenopsis, and Taiwan has established the status of the world Phalaenopsis breeding center as early as the 1980s. After nearly 30 years of rapid development, my country's mainland has also become one of the world's most important Phalaenopsis production and consumption places. However, due to the late start of breeding work, speeding up the cultivation of independent varieties is an urgent task for mainland Phalaenopsis breeders.

Problems solved by technology

[0004] 1. The hybridization efficiency of Phalaenopsis is not high

[0005] Every time Phalaenopsis is hybridized, it is necessary to walk between different parents. There are many varieties of Phalaenopsis, and there are many parental materials. When performing hybridization, they often need to occupy a larger position. When the parents are far away, walking back and forth is a lot of waste. time

Although the flowering period of Phalaenopsis is longer, the best time for hybridization of pistils and stamens is different. The best stigma receptivity is within 10-15 days of flower opening, and the best pollen vigor is within 1-7 days of flower opening (fig. Lan et al., 2017), so how to complete the hybridization work quickly and efficiently in an effective time and improve the hybridization efficiency of Phalaenopsis is an urgent problem to be solved

[0006] 2. There is no effective way to preserve Phalaenopsis pollen

[0009] 3. The breeding process takes a long time
