Embodiment 1

[0016] Crossbreeding of the new variety 'Fendai Xiangfei':

[0017] Using Primula denticulatessp.sinodenticulata from southern Yunnan as the female parent and Primula denticulate ssp.sinodenticulata from Lijiang in the northwest of Yunnan as the male parent, the two kinds of flowering stages were carried out. Hybridization, the hybridization time is at 9-11 o'clock in the morning, the pollen of Primula diaphyllum from Lijiang is conferred on the stigma of Primula diaphyllum from southern Yunnan with a writing brush, bagged (sulfuric acid paper bag, Bag size: 10X8 cm). Remove the bag after 7 days. After 20 days of pollination, when the fruit turns brown, the fruit is collected, and when the seeds are scattered from the fruit, the seeds are collected for sowing. Hybrid seed sowing is carried out according to the following steps:

[0018] A. Preparation of sowing basket and sowing soil: the sowing basket adopts a plastic basket of length×width×height (45cm×30cm×12cm); the sowi...

Abstract

The invention provides a hybridization breeding method of a novel primrose variety 'Beautiful Xiangfei', which comprises the following steps: intraspecific hybridization and single plant selection. Artificial intraspecific hybridization, seeding, sowing, seedling reculturing, transplanting and cultivation are carried out to primula denticulatessp. sinodenticulata balf.f.et forr.)W.W.smith from Southern Yunnan which serves as a female parent and primula denticulatessp. sinodenticulata balf.f.et forr.)W.W.smith from Lijiang which serves as a male parent. A single plant which has green leaves, robust growth, light pink flowers, white middle part, yellow crown throat, one head-shaped inflorescence, strong scape, large inflorescence, fragrance and a flowering phase of 2 to 3 months is selectedfrom an F1 generation, and then pollinated, seed collected, planted and screened. An individual which has light pink flowers, white middle part, yellow crown throat, one head-shaped inflorescence, 34to 79 flowers in each inflorescence, the single flower corolla diameter of 1.1 to 1.4cm, the inflorescence diameter of 3.3 to 4.1cm, the scape height of 11 to 28cm, fragrance and the flowering phase of 2 to 3 months is selected from a cultivated F2 generation as the novel variety of 'Beautiful Xiangfei'.

Description

Technical field: [0001] The invention relates to a method for selecting and breeding a new flower variety, in particular to a hybrid breeding method for a new primrose variety-Fendai Xiangfei. technical background: [0002] There are about 500 species of primroses in the world, mainly distributed in the temperate zone and alpine regions of the northern hemisphere, and only a few species are distributed in the southern hemisphere. The modern distribution centers of this genus are along the sides of the Himalayas to Yunnan and western Sichuan. China is one of the countries with abundant natural distribution of primroses. There are 293 known and published species, 21 subspecies and 20 varieties. Yunnan is located in the southwestern border of China, and is rich in plant species, especially Primroses. Most of the known species in my country (about 159) are distributed in Yunnan. Primroses are one of the most beautiful ornamental plants with their gorgeous flowers. The United K...
