3. History and development of plant breeding
 Domestication The process of bringing a wild species
under human management is referred to as
 - Domestication may be the most basic method of plant
breeding
 - Domestication continuous today and is likely to continue
for some time in future - Ex : In case of timber trees
medicinal plants, microbes
 - During the long period of historic cultivation natural
selection has definitely acted on the domesticated species.

4. Wild plant spp.

5. Purpose of domestication
 The man has brought wid plants under his control
For various urpose
Food , clothes ,shelter ,medicines ,aesthetic
Process of domestication-
1- natural selection 2- spontaneous generation
3- selective breeding method 3- wild mutation

primarily to international human activity is called a
cultigen

7. Difference between wild and domesticated plant
s.no Particuler Wild species Domesticated spp.
1 Plant habit perennial Annual
2 Yield potential Poor High
3 Resistance to biotic
and abiotic stress
Very high Low to medium
4 Germination Poor High
5 Dormancy High Low
6 Grain quality Poor Very good
7 Toxic substances More Less or absent

8. Limitations
 Domestication is a very slow process taken 100 of year
 Wild plant have several undesirable trait
 Reduction of resistance of plant
 The domestication makes the plant human depend for
their reproduction .
