Study on heritability and field experiment design

Recently, I cleaned up the learning materials , I found this one in my previous collection PPT, Very good , Share and learn .

1. PPT Title and author

2. Choose the appropriate

Selection correspondence is a very important concept in breeding , When we choose for certain traits , Have a certain amount of knowledge , Ensure that certain choices are appropriate to ensure the efficiency of selection .

There needs to be variation in the population , Pedigree selection is invalid

High heritability , Choose the appropriate size , The group size can be smaller

3. Several definitions of heritability

• • 
    
• Real heritability
• Narrow sense heritability
• Generalized heritability
  • 
    

4. Heritability depends on the population

5. Control the environmental error by experiment

6. Calculation of heritability of parent-child regression

7. Full sib design

8. Half sib design

9. NC I Experimental design

10. NC II Experimental design

11. Diallel cross

12. Breeding value

13. Multiple environmental tests

13. Experimental design and analysis

Three principles of experimental design ： Random , Repetition and local control

14. Several common experimental designs

For a few hours ：

• • 
    
• Completely random
• Random complete block
• Latin square
  For a long time ：
• alpha- Lattice experimental design
• Federer test
  spatial analysis
• post-blocking
• spatial analysis
  
  • 
    

15. Completely randomized trial

16. Completely randomized

17. How to deal with more varieties or treatments ？

18. Incomplete block design

19. Calculating heritability

Different inbreeding coefficients , Can't be the result of .

20. Other factors that need to be considered in the experimental design

21. How to evaluate in the experimental design
