GENETICALLY MODIFIED WHEAT PLANTS AND PROGENY AND METHOD FOR PRODUCTION OF HYBRID WHEAT

摘要

The invention relates to wheat plants genetic modification and the resultant line of these plants, as well as a hybrid wheat production method of using these plants. The obtained genetically modified wheat by performing homologous pairing to add a fertility-restorer chromosome which contains telomere Chromative homologous to another wheat chromosome carrying a recessive male sterility gene. The fertility-restorer chromosome contains a major portion of foreign Chromative from another species of wheat, and a fertility restorer gene and at least one marker gene. The genetic structure of the wheat plant, in a preferred form can be described as follows: 20 '' + 4B (ms) + [4m (on 4th) - 4EL - 4BL]. These plants have a meiotic stability and are used to produce hybrid wheat strains.
