Intra Specific Hybridization
Hybridization within a species involving known parents of two varieties. The varieties involved in hybridization have welldefined characters. They are crossed to achieve heterosis. The offsprings are subjected to selection to eliminate of undesirable combinations.Heterosis
The hybrids express vigour in a particular character, by virtue of which they are superior to their parents. This phenomenon is called hybrid vigour or heterosis.Inter Specific Hybridization
Two parents of known well defined characters belonging to two different species within a genus are crossed to achieve heterosis.Some important hybrids (both inter specific and intra specific) are listed in
Similar to selection process, hybridization and other breeding methods are aimed at improving specific characters in the crop. They could be yield potentiality, quality improvement, resistance to pests and diseases etc., The heterosis in offsprings is of great significance in breeding programmes.
