Abstract:
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 from 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 these evaluation 110 entries of F2 segregating generations and 306 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, 98 entries of F2, 46 entries of F3, 133 plants of F4 and 158 lines of F5 were selected.
