What is the purpose of testing newly selected lines in farmers' fields in plant breeding?
To evaluate the yield and other agronomic traits of the selected lines
To select the superior recombinants among the progeny of the hybrids
To collect and preserve wild relatives of the crop
None of the above
The purpose of testing the newly selected lines in farmers' fields is evaluation of the yield and other agronomic traits of quality, disease resistance, etc. Therefore, option a) is the correct answer as it accurately summarizes the purpose of testing the newly selected lines in plant breeding. Option 2) is incorrect as it refers to the previous step of selecting and testing superior recombinants among the progeny of the hybrids. Option 3) is also incorrect as it refers to the step of collecting and preserving wild relatives of the crop, which is a different step in the breeding process. option 1) is the correct answer.
