SELECTIONSelection (selectio - choose) - the science of creating new and

creating new and improving existing breeds of animals, plant

varieties, strains of microorganisms
Selection is also called a branch of agriculture, which bred new varieties and hybrids of crops and breeds of animals

Слайд 3 Selection of plants
The main methods of selection in

Selection of plantsThe main methods of selection in selection of plants

selection of plants are selection and hybridization

Hybridization (breeding) –

the desired traits of parent plants are crossed and seen in offspring

Слайд 4 There are 3 modes of breeding in plants:
-

There are 3 modes of breeding in plants:- Inbreeding- OutbreedingInbreeding –

Inbreeding
- Outbreeding
Inbreeding – the breeding of genetically closely related

plants.
This brings to desired traits of plant (AA), but after some generations it can bring to recessive homozygote trait (aa).

Modes of breeding in plants

Слайд 5 Outbreeding - getting progeny from manufacturers that are

Outbreeding - getting progeny from manufacturers that are not related geneticallyThe

not related genetically
The aim is to create offspring in

which viability, productivity is higher and higher resistance to unfavorable conditions
Offspring from such crosses are called hybrids, and they exceed the number of features both parental forms - a phenomenon called heterosis

Modes of breeding in plants

Слайд 6 Basic principles of breeding animals do not differ

Basic principles of breeding animals do not differ from the principles

from the principles of plant breeding
However, the selection of

animals has some features:
- they are characterized by sexual reproduction only
- mostly very rare generational change (in most animals in a few years)
- the number of individuals in the offspring is small

Selection of animals

Слайд 7 The best (human needed) characteristics of domestic animals

The best (human needed) characteristics of domestic animals are:- milk yield-

are:
- milk yield
- milk fat
- meat quality
- quality of

wool
- egg-laying qualities

Selection of animals

Слайд 8 Modes of breeding in animals
There are 2 ways

Modes of breeding in animalsThere are 2 ways of breeding in

of breeding in animal selection:
- inbreeding
- outbreeding
Outbreeding -

unrelated cross between individuals of the same species or different species of animals, with a further strict selection leads to the maintenance of useful skills and to strengthen them in a number of next generation

Modes of breeding in animalsIn domestic animals, the phenomenon of heterosis

phenomenon of heterosis is seen
Hybrids of the first generation

are stronger and more viable
For example, a mule - a hybrid of a mare and a donkey
This is a strong, hardy animal that can be used in much more difficult circumstances than the parent form
