Heterosis,or hybrid vigor refers to the phenomenon in which hybrids between two inbred varieties or lines exhibit greater than their inbred parents.Heterosis in plants is associated with increases in grain yield,vegetative growth rate,tolerance to pests and environmental stress,accelerated maturity,and many other changes in desirable agronomic characteristics.
