Crop Breeding — Quiz

Test your understanding of crop breeding with 5 practice questions.

Practice Questions

Question 1

Which breeding method involves repeated backcrossing to transfer a specific desirable gene from a donor parent to a recurrent parent, while maintaining most of the recurrent parent's genetic background?

Question 2

In the context of crop breeding, what is the primary advantage of using 'doubled haploidy'?

Question 3

Which statistical parameter is most critical for predicting the response to selection in a crop breeding program?

Question 4

If the narrow-sense heritability ($h^2$) for a quantitative trait is $0.40$ and the selection differential ($S$) is $0.30$, what is the expected genetic gain ($R$) in the next generation?

Question 5

What is the primary role of 'genomic selection' in modern crop breeding?
