Method for selectively breeding specific cockscomb by chromosome chimerism principle

Abstract

A method for selectively culturing the specific cockscomb by chromosome chimera principle includes such steps as using automutation to generate chimeric plant as mother plant; treating the seeds of the said mother plant by gamma ray; selectively culturing the stable chimera of specific cockscomb; free crossing and collecting seeds at particular position; and targeted hybridization. The resultant varieties of cockscomb features different colours on its same inflore scence, flower, stem and leaf.

Description

Technical field [0001] The invention relates to a method for breeding special flowers, in particular to a method for breeding specific celosia by using the principle of chromosome mosaicism. Background technique [0002] The magical nature has created everything in the world, including tall trees, beautiful flowers and other colorful plants. Generally speaking, every plant has a certain number of stable chromosomes, they only grow the same leaves and bloom the same color flowers. However, sometimes you can also see some special plants with leaf color inlays and multi-color flowers, such as Phnom Penh Ruixiang, colorful petunia and mosaic dahlia. They are plant chimeras, which consist of cells with different genetic material to form a plant body and exhibit two or more relative traits at the same time. [0003] There are four main reasons for chimera formation. One is virus infection, the other is chromosomal mosaicism, the third is the effect of gene mutation...

AI Technical Summary

Problems solved by technology

[0005] One is that the occurrence of chimeras in nature is quite rare; the other is that the natural chimeras reproduce slowly under normal conditions; the third is that most chimeras cannot maintain chimera characteristics under the condition of seed reproduction; The genetic characteristics of varieties that maintain chimera characteristics through seed propagation are unclear, which is not conducive to the selection of new chimera varieties for specific flowers

Therefore, under the conditions of the current prior art, it is difficult to cultivate a large number of specific flowers of chimeras, especially it is more difficult to reproduce them with their seeds.
