4. Selection and selfing of superior recombinants:
The progeny of the hybrids are observed for the desirable combination of characters.
Such plants are selected and carefully observed and scientifically evaluated for the success of breeding objective.
The plants which are superior to both the parents and exhibit hybrid vigour are collected.
Such plants are self pollinated for few successive generations to get homozygosity, due to this plant attains a state of uniformity and characters do not segregate in the progeny.
5. Testing, release and commercialization of new cultivars:
The newly selected lines are evaluated for their productivity and other agronomic characters like disease resistance, quality of crop etc.
In the beginning such evaluation is done by growing these plants in research fields under controlled and ideal conditions of fertilizer application, irrigation, usual crop management practices etc. and their performance is recorded.
Such plants are then grown in natural fields for atleast three growing seasons in different agroclimatic zones of the country where the crop is usually cultivated.
All such tests are carried out by expert agencies like ICAR (Indian Council for Agricultural Research) in India.
Variety release committee recommends the release of improved variety under new name with the permission of Government.
