Embodiment 1

[0031] A kind of breeding method of cyclamen, comprises the steps:

[0032] (1) During the full flowering period from mid-November to mid-March of the following year, choose parents with strong plants and vigorous growth; the flowers should be large, bright in color, neat in shape, stretched, fully reversed and upturned;

[0033] (2) Manual removal of male petals: From the side of the semicircular arc of the flag petal, use tweezers to clamp the top of the flag petal and the connection between the flag petal and the flower statue. The angle between the tweezers and the flower back line is 40-50 degrees. Then clamp the petals and pull them out completely. The direction of force when pulling out is consistent with the direction in which the cyclamen flowers grow;

[0034] (3) Measure the pollen viability of artificially emasculated flowers, stain with TTC solution, take samples from the field every 3 hours from 8:00 in the morning, take pollen from 3 flowers each time, mix them,...

Abstract

The invention discloses a cyclamen breeding method. The cyclamen breeding method comprises the steps of firstly optimizing the male and female parents of the cyclamen, next, hybridizing the male and female parents and screening out descendants, next, increasing the screening speed by use of a tissue culture technique, thereby saving the cost of autumn identification. A reasonable castration method is adopted, and the castration success rate in once petal removal is relatively high and the ovary cannot be damaged, and therefore, the working efficiency and the hybridizing maturing rate are increased. The working efficiency is more than twice higher than that of the traditional method, and the hybridizing maturing rate is nearly once higher than that of the traditional method. No bag needs to be put on for isolation, and the labor can be saved; in addition, the breeding process is accelerated by use of the tissue culture rapid-propagation method, and the economic benefit is greatly improved.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a cyclamen breeding method. Background technique [0002] Cyclamen has aliases such as radish crabapple and rabbit ear flower, and it is also known as Quma flower and Madonna flower in Western countries. Originally produced in Persia, it has not been introduced to my country for a long time. Cyclamen is a Christmas flower in western countries, and it is also the national flower of San Marino. In Europe, cyclamen means "parting". [0003] Cyclamen bear fruit after flowering, and the fruit matures from May to June. Seeds should be collected when the fruit starts to turn from green to yellow, and should not be picked until the capsule cracks, because once the capsule cracks, the seeds are easy to fall off. The harvested seed tips are stored in a cold place, generally at 2°C, and can still germinate well after 4 and a half years. In order to make the seed varieties pure, ...
