Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0033] figure 1 It shows the realization flow of the breeding method of the peach-red lotus hybrid provided by the embodiment of the present invention.

[0034] The breeding method of the pink lotus hybrid comprises the following steps:

[0035] In step S101, adopt the three-cross method of small flower Lingjian × (pink purple Lingjian × white flower Lingjian), select a variety with excellent comprehensive traits as the female parent of the cross, and use the parent with important target traits as the parent of the second cross to obtain a three-cross Hybrid;

[0036] In step S102, in the aseptic in...

Abstract

The invention discloses a seed breeding method of a peach nopalxochia ackermannii crossed seed. A three-way cross manner of nopalxochia phyllanthoides*(pink and purple nopalxochia ackermannii*white flower nopalxochia ackermannii) composite-crossing is adopted to obtain a three-way cross crossed seed; in a sterile insulation chamber, a sterile plant of the three-way cross crossed seed F1 is obtained; a sterile seedling of the three-way cross crossed seed F1 is subjected to multiplication culture and rooting culture, and hardening-seedling treatment, and then is transplanted; water and fertilizer management are carried out on the transplanted cultured seedling of the three-way cross crossed seed F1, and disease control is enhanced; and later generations of the three-way cross crossed seed F1 are selected and identified. According to the seed breeding method disclosed by the invention, a good single plant of the nopalxochia ackermannii crossed seed, which integrates good properties of a plurality of parents, can be obtained through the composite-crossing three-way cross manner; the selection of a crossed seed phase and a seedling period is enhanced through crossed seed tissue culture, and the propagation coefficient of the later generations of the crossed seed is more rapidly increased; a clone of the good single plant of the crossed seed is established by combining cutting propagation; the seed breeding time of the good nopalxochia ackermannii composite-crossing crossed seed is shortened by 2-3 years; and the seed breeding method is strong in practical applicability and has strong popularization and application values.

Description

technical field [0001] The invention belongs to the field of flower genetics and breeding, and relates to a method for breeding hybrids of peach red lotus. Background technique [0002] Lingjian lotus, also known as Lingjian, peacock cactus, peacock orchid, and safflower peacock, belongs to the genus Lingjian in the cactus family.
