| Abstract: | Dwarf male sterile wheat is a Taigu genic male sterile wheat with dwarf marker. According to the characteristics of the wheat and the principle of recurrent selection, a simple and practical method of population improvement has been developed. The principal techniques include that to compose a fine basic population; introduce good gene(s) into the population via controlled pollination; discard the bad fertile plants before flowering to increase the frequency of beneficial genes; extend gene recombination by inter crossing male sterile plants with fertile ones; and select and harvest suitably the dwarf male sterile plants. Using the above mentioned method and technique, several dwarf male sterile wheat improved populations have been set up. |
