Yes it is called hybrid vigor when you take to inbred lines and cross them to each other you receive a large dose of hybrid vigorWhen breeding two IBL together that are both less vigorous, will the birth of these two strain crossed make it a vigous plant again? or will all of its kids be less vigour to?
