Activities in plant breeding methods.pptx

This presentation gives an idea about the different activities carried out in plant breeding.

1. Plant Breeding Dr. Ravindra D. Madhekar Assistant professor, Dept. Of Botany, S. B. E. S. College of Science, Aurangabad (Maharashtra) Activities

2. Methods of Plant Breeding Domestication, Plant Introduction and acclimatization Selection Hybridization Mutation breeding

3. Activities in Plant Plant Breeding Desirable changes in genotype brought about by inter-related, inter-dependent activities. Creation of variation Selection Evaluation Multiplication Distribution

4. 1. Creation of variation Variation means differences among individuals of a population or species for a specific character . source of raw material for selection. These are heritable and useful in selection . S uccess of a breeding programme depends on it. It can be done by domestication , germplasm collection, plant introduction , hybridization, polyploidy , mutation, somaclonal variation and genetic engineering.

5. 2. Selection Identification and isolation of plants with the desirable combination of characters from population. Carried out on the basis of phenotypic characters. Yields an improved line/strain. Efficiency of this activity determines the success of the breeding programme.

6. 3. Evaluation The newly selected lines/strains/populations are tested for yield and other traits and their performance is compared with existing best varieties called Checks . If the new lines/strain/population shows superior performance to the checks, it is released and notified as a new variety. 4. Multiplication This step concerns with large scale certified seed production of the released and notified variety. 5. Distribution Certified seed is ultimately sold to the farmers who use it for commercial crop cultivation .
