Embodiment 1

[0048] 1) Chongming narcissus bulb selection

[0049] After the bulbs are harvested, select the healthy and pest-free Chongming narcissus 'Yulinglong' flowering bulbs, and store them in a cool and ventilated place for 10 weeks to break dormancy. The flowers of Chongming narcissus 'Yu Linglong' are shaped like figure 1 shown.

[0050] 2) Radiation dose

[0051] The bulbs of Chongming narcissus stored for 10 weeks were irradiated with 60Coγ, and the radiation dose was 10Gy.

[0052] 3) Breeding of new germplasm

[0053] (1) The flowering bulbs of Chongming narcissus treated with 60Coγ radiation were planted in a greenhouse with isolation and cooling facilities. The time interval between radiation treatment and planting was less than 1 week. The planting container was a 50×80cm plastic turnover basket, and the bulbs were planted in the same In a turnover basket, cultivation management. Observe the bulb germination time, leaf shape, flowering time, flower shape and other trai...

Embodiment 2

[0067] 1) Chongming narcissus bulb selection

[0068] After the bulbs are harvested, choose healthy, pest-free flowering bulbs of the Chongming narcissus 'Calendula Yintai' and store them in a cool and ventilated place for 10 weeks to break dormancy. The flowers of Chongming narcissus 'Calendula Yintai' are shaped like image 3 shown.

[0069] 2) Radiation dose

[0070] The bulbs of Chongming narcissus stored for 10 weeks were irradiated with 60Coγ, and the radiation dose was 10Gy.

[0071] 3) Breeding of new germplasm

[0072] (1) The flowering bulbs of Chongming narcissus treated with 60Coγ radiation were planted in a greenhouse with isolation and cooling facilities, and the time interval between radiation treatment and planting was less than 1 week. The planting container is a plastic turnover basket of 50 × 80 cm, and 40 heads are planted in each frame, a total of 1 frame, and the cultivation management is the same as in Example 1. Observe the bulb germination time, l...

Abstract

The invention relates to a Chongming narcissus new variety selection method and cultivation method. The selection method includes: performing 60 Co gamma radiation treatment on Chongming narcissus bulbs, wherein the radiation dose is 8-12 Gy; cultivating the Chongming narcissus bulbs for at least 2 growth seasons after radiation treatment; planting the treated Chongming narcissus bulbs during 1 week after radiation treatment, and selecting bulbs which have significant character differences from the original variety and have ornamental value; performing later growth season cultivation on the selected bulbs; and finally selecting bulbs having a stable ornamental character, and obtaining a variant new variety of the Chongming narcissus. The selection method is easy to operate, is low in cost, and is high in mutation probability; through 3 growth season cultivation, the variant new variety is stable in ornamental character; during selection, the new variety is cultivated through soilless substrate, the problem of severe virus accumulation and bulb degeneration can be solved, and the excellent characters of the Chongming narcissus can be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of plant germplasm innovation, and specifically relates to a method for breeding new germplasm of Chongming narcissus and a cultivation method thereof, and more specifically relates to a method for creating new germplasm of Chongming narcissus by 60Coγ radiation and the development of new germplasm of Chongming narcissus Cultivation method. Background technique [0002] my country has a long history of narcissus cultivation, and the introduction and cultivation of narcissus began about 1300 years ago. Narcissus is one of the top ten famous flowers in my country, known as "Lingbo Fairy", and has important ornamental value and economic value. At present, the main producing areas of narcissus in my country are Zhangzhou, Xiamen, Fuzhou in Fujian, Chongming Island in Shanghai and Putuo in Zhejiang. The narcissus cultivated in these areas are all Narcissus tazetta varieties (N.tazetta var.chinensis Roem). [0...
