Methods of mass selection

There are different methods of mass selection

• Hallets Mass selection 1869:-
  
• In this case, the plants are raised in the most optimum environment and best performing plants from that population are selected.
• These selected plants are bulked and advanced for next generation.
• Rimpai’s (1867):-
  
• Here the plants are grown either in the normal conditions or in stress conditions or in an unfavourable environment and from these stress conditions plants with desirable economic characters are selected and bulked for next generation.
• Fanned method:-
  
• The seeds are blown with wind and heavy seeds will be collected and raised in next generation.
