Question

Explain pure line selection.

Answer 1

• Pure line selection involves selecting progeny from a single self-fertilised homozygous plant called a pure line.
• Many plants are selected, and their progenies are tested in fields.
• The best progeny is chosen and saved as a new variety.
• Unlike mass selection, fewer plants are selected and tested individually.
• The resulting variety is genetically pure and stable.
• It is also used in cross-pollinated crops for developing pure lines as parents in hybridisation.
