## Key points

- Coefficient of Parentage (COP) is important in plant breeding
- COP calculates expected inbreeding between two individuals
- Recent research by Hernandez-Suarez and Montesinos Lopez shows different methodology needed for calculating COP between strains
- Incorrect methodology can lead to overestimation of inbreeding, negatively impacting crop improvement programs
- Hernandez-Suarez and Montesinos Lopez developed a simple approach for calculating correct COP between strains
- Accurate COP calculations are crucial for successful outcomes from crop improvement programs.

## Summary

In the field of plant breeding, the Coefficient of Parentage (COP) is a crucial calculation used to determine the expected inbreeding of offspring between two individuals. Recent research by Carlos Hernandez-Suarez and Osval Montesinos Lopez has revealed that calculating the COP between strains requires a different methodology than what is used for individual calculations. If this methodology is not followed correctly, it can lead to an overestimation of inbreeding which can have negative consequences for crop improvement programs. To address this issue, Hernandez-Suarez and Montesinos Lopez have developed a simple approach for calculating the correct coefficient of parentage between strains. This research highlights the importance of accurate COP calculations in plant breeding and emphasizes the need for continued refinement and improvement in this area to ensure successful outcomes from crop improvement programs.
