Question

Selection of homozygous plant is_______.

• A. mass selection
• B. pure line selection
• C. mixed selection
• D. none of the above

Answer 1

The correct option is B

pure line selection

Pureline varieties are homozygous and homogeneous as they are genetically similar and true breeding. Such varieties possess narrow genetic base so they are more susceptible to diseases, and have poor adaptability. A pure line breeding method is normally used for self-pollinated crops, but has importance in breeding of inbred lines that are used to make hybrids in self or cross pollinated crops
