23 Jul Haploid soybean
Abstract
The invention discloses a haploid soybean of genetic engineering series. A discovery of the haploid soybean of the genetic engineering series is as follows: a growing plant induced and differentiated from a damaged tissue which is separated from a conventional soybean and subjected to artificial culture causes genovariation in terms of reproduction. A variation plant is bloomed for twice in terms of reproduction; haploid flowers which are highly sterile are bloomed in the first turn; and self-fertile flowers are bloomed in the second turn, and such a physiological phenomenon can be entailed to a first filial generation of cells to form a new type soybean which generates the haploid soybean flower maintenance line. The application of the haploid in terms of breeding is as follows: the haploid soybean abortion is uncovered with no doubt and a double-fertilization green plant is obtained. In terms of haploid breeding, genes are recombined and chromosomes are doubled to form a homozygous diploid, and a triploid plant can be enabled to form a hexaploid plant and the like. According to the invention, species production is improved in a multiplied manner, protein is also correspondingly increased, a steady and long-term hybrid medium body is also provided for tests, and application of hybridization and distant hybridization is improved to a higher level.
