All bloodlines start with the first cross. The first cross that led to the formation of the bloodline blakliz was done in 2000-2001 season. The first attempt to set it as a bloodline was three years after in 2003. From that first cross to the present a number of breeding techniques were applied to achieve the desired bloodline objectives.
Some of these techniques were conventional, some not. RB Sugbo Gamefowl Technology and the creator Rey Bajenting have applied some not very usual techniques based on their own principles. Among these pragmatic ideas were the principles of practical purity and progressive mating sequence.
