The main steps involved in plant breeding are as follows:
1- COLLECTION OF VARIABILITY
Genetic breeding is the root of any breeding programme. In plant breeding collection of variability is done done by collection of plant varieties. It consists of -
a) Cultivated improved varieties
b) improved varieties that are no more cultivated
c) old local or desi varieties
d) wild species related to the crop species
2-EVALUATION AND SELECTION OF PARENTS-
The germplasm is evaluated so as to identify plants with desirable combination of characters
3- CROSS HYBRIDIZATION AMONG SELECTED PARENTS
The desired characters have very often to be combined from two different plants (parents)
4- SELECTION AND TESTING OF SUPERIOR RECOMBINANT
This step consists of selecting, among the progeny of the hybrids, those plants that have the the desired character combination
5- TESTING, RELEASE AND COMMERCIALIZATION OF NEW CULTIVARS:
The newly selected lines are evaluated for their yield and other agronomic traits of quality, disease resistance, etc. Ultimately a new pure line, population or hybrid that is superior to the existing varieties as well as to other new material may be released as new variety.
