Problems solved by technology

Moreover, the breeding methods of Hualien mostly adopt traditional conventional hybrid breeding, which takes a long time and costs a lot of money. The traditional intraspecific or interspecific hybridization is limited by the narrow genetic genes of the variety. The flower type and color of the selected Hualien varieties are single. short flowering period

Embodiment 1

[0017] Embodiment 1: Star Peony (approved by the Variety Approval Committee of Fuzhou City, Jiangxi Province in 2005, numbered Funong Shentui [2005005]) is a new large-scale Hualien variety selected and bred by the method of the present invention.

[0018] Kong Kongkonglian 2 (approved by the Variety Approval Committee of Fuzhou City, Jiangxi Province in 2005, serial number Funong Shentuizi [2005002]) was used as the female parent and Guangchang Bailian 979501 ​​was used as the male parent for hybridization. The hybrid breeding process is as follows:

[0019] ①. Parental selection: In the first year, select plants with strong plants, vigorous growth, and no diseases and insect pests as parents.

[0020] ②, Bagging isolation: 1-2 days before the first flowering of the selected parents, carry out bagging isolation. The bagging is made of thin kraft paper and transparent cellophane, and both parents should be bagged for isolation.

[0021] ③. Collect pollen: collect parental poll...

Abstract

The present invention belongs to the field of crop breeding technology, and is especially process of breeding new Hualian lotus variety. The new Hualian lotus variety is bred with No. 1 space lotus, No. 2 space lotus or No. 3 space lotus as female parent and Guangchang white lotus 979501 or Guangchang white lotus 97-1 as male parent, and through parent breeding, bagging to separate, collecting pollen, artificial pollination, eliminating bag, collecting hybrid lotus seed, further breeding and selecting. The present invention utilizes rich variant resource and combines with traditional hybrid breeding technology to breed new Hualian lotus variety in short period.

Description

[0001] Field [0002] The invention selects and breeds a new variety of Hualien by means of space-borne mutation breeding technology combined with traditional cross-breeding technology, belongs to the field of crop breeding, and particularly relates to a breeding method for a new variety of Hualien. technical background [0003] At present, the breeding of Hualien varieties in my country is mostly concentrated on medium and small potted or bowl lotus varieties, and the breeding of large Hualien species is still blank in my country. Moreover, the breeding methods in Hualien mainly adopt traditional conventional hybrid breeding, which takes a long time and costs a lot of money. Traditional intra-species or inter-species hybridization is limited by the narrow genetics of the species. The selected Hualien varieties have a single flower type and color. Flowering period is short. Contents of the invention [000...
