In maize, hybrid vigour is exploited by:-a)Bombarding the seeds with D...
Heterosis or hybrid vigour means the increased vigour (size, strength etc.) of a hybrid than its parents.
As it is a hybrid, it is always superior to either of its parents. In plants, heterosis is expressed in the form of height, viability, a greater yield of fruits and seeds, increased resistance to environmental factors, resistance to diseases, pests and better seed germination.
Heterosis has been commercially exploited in many crops like maize by a crossing of two inbred parental lines. The vigour is lost after a few generations.
So, the correct answer is 'Crossing of two inbred parental lines'
