General principles involved in this method is that, only one ( single) seed collected from each of the F2 plants ( 10000 to 20000) and
then bulked to grow the next ( F3) generation.
Similar practised is continued till F5 or F6 generation, when the plant would become nearly homozygous.
In F5 and F6 generation, when individual’s plants are selected and harvested separately.
Their progenies are also grown separately in next generation.
Selection is done among the programme ad promising one is select to conduct replicated yield trails and quality test conducted in F7- F8 generation and coordinated yield trial in F9- F10 generation
