Question

Selection is a method of plant breeding based on

• A. Phenotype
  
• B. Plant breeding
• C. Performance
  
• D. Genetics

Answer 1

Answer: (A), (C)

Phenotype
Performance

• Plant breeding is the purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation, give better yields and are disease resistant.
  
• The important steps in breeding a new genetic variant of a crop are 1) Collection of variability 2) Evaluation and selection of parents 3) Cross hybridization among the selected parents 4) Selection and testing of superior recombinants 5) Testing, release and commercialization of new cultivars.
  
• Selection and testing of superior recombinants- This step consists of selecting, among the progeny of the hybrids, those plants that have the desired character combination. This method of selection depends mainly on selection of plants according to their phenotype and performance.
  
• So, the correct answer is 'Plant breeding'.
