In the case of breeding for resistance, if the resistance is governed by polygenes, which method of selection is adopted?

AClonal selection

BMass selection

CPedigree method

DPureline selection

Answer:

C. Pedigree method

Read Explanation:

The pedigree method of selection is used when breeding for resistance if the resistance is governed by polygenes. The pedigree method is a commonly used breeding method that can be used to develop both self-pollinated and cross-pollinated crops. It involves selecting highly heritable traits in individual plants in early generations. Yield testing is usually done once homozygous lines are developed.
