بررسی در توده های دورگ و نسل های در حال تفکیک جو در ایستگاه زرقان در سال زراعی ‮‭85- 86‬

In the hybridization method of breeding self fertilized crops, two varieties are crossed, their characters are combined and Plants with desirable features of the parents are selected trom the segregating progenies. Genetic segregation will begin with the F2 generation, and heterozigocity will be reduced by one half with each succeeding self generation. In this evaluation 164 entries ofF2 segregating generations and 120 entries of other generations (F3-F5) participated. Modified bulk method was used in selection of plants with desired combination of characters within F2 and F3 generations and for F4 generation, pedigree method was used. In F5 generation in which almost genetic purity was reached, line selection was done. Among these materials, 40 entries of F2, 79 entries of F3, 71 plants of F4 and 51 lines ofF5 were selected.
