Embodiment

[0068] The breeding process of JLF series pink varieties:

[0069] 1. Breeding goal: to breed new flower color varieties and improve the flower shape of offspring at the same time.

[0070] 2. Screening and breeding of the female parent: The female parent is a Japanese bright pink variety with good resistance, especially strong adaptability to high temperature in summer. The plant type of the female parent F1 is plump and compact, the leaf pattern is horseshoe stripes, a large-flowered variety, but the width of the petals is slightly narrower than that of the male parent, the flower type is standard, the reverse is better, the height of the pedicel is moderate and neat, and the flower volume is large. The one-time flowering amount can reach 40-50, and the total flowering amount is more than 100. About 60-70% of the female parent F1 is bred into the F2 generation through sister crossing within the variety, and the remaining 30-40% are dark pink, light pink, orange pink, purple...

Abstract

The double crossing cyclamen breeding process includes screening the parents, F1, F2 or F3, for double crossing; and the selective mating of the parents for double crossing to hybridizing to obtain the double crossed seed. The present invention has shortened cyclamen hybrid breeding period of 6 years, contrasting to conventional 20 years, greatly raised hybrid breeding efficiency, and lowered hybrid breeding cost.

Description

technical field [0001] The invention relates to a method for cultivating plant hybrids in the field of biotechnology, in particular to a method for double-cross breeding of cyclamen. Background technique [0002] Cyclamen is a plant of the genus Cyclamen of the Primula family. Because of its unique flower shape, various varieties and winter blooms, it is very popular among people. It is one of the main potted flowers for Christmas, New Year's Day and Spring Festival at home and abroad. The production of potted plants relies on seed propagation. At present, domestic cyclamen breeding mostly adopts the traditional crop breeding method, that is, firstly, multi-generational purification of cyclamen is carried out to form inbred pure lines with stable properties, and then the parents of different inbred pure lines are selected to form inbred pure lines with consistent properties. Hybrids. Because the cyclamen cultivars are highly heterozygous, it takes a long time to purify the...
