Recurrent method of selection in Plant Breeding with Procedure and notes

 What is Recurrent Selection?

• It is the method for selection of desirable individuals that are superior inbreeds from the population followed by recombination of the selected individuals to form a new population
• Recurrent method is a cyclic process that is repeated followed to isolate and improve the superior inbreeds.
• Involves the isolation of superior inbreds from the population and utilize them in hybrid and synthetic varieties.
• The process of Evaluation of Plant Population, Selection of superior plants from population and Developing a population is repeated.

                                       

STEPS INVOLVED IN Recurrent METHOD OF SELECTION

• First Year Plants: Several superior plants selected. Selected plants are self-pollinated, Harvested Seeds evaluated.
• Second Year Plants: Separate progeny rows are grown from the selected plants in next generation. The progenies are intercrossed in all possible combination by hand.
• Progeny rows raised by collecting seeds from second year plants- composited seeds from intercross.
• Repeat the same process as in First- and Second-Year Plants, that’s why it is called as Recurrent Selection.
