Abstract

In plant science selection plays a key breeding approach for improving economic features in many plants’ kind. Selection techniques vary based on the mechanism of reproduction. Self-pollinated crops employ pure line and mass selection methods, whereas cross-pollinated crops use recurrent selection. Vegetatively propagated plants use clonal selection. Regardless of Phenotypic recurrent selection is a successful approach for enhancing polygenic features. While increasing the frequency of desirable genes for economic characters can help maintain high genetic variability in heterozygous populations, the efficiency and effectiveness of this approach may not be satisfactory in most cases. This is due to phenotypic selection being influenced by environmental factors and genotypic selection taking at least 2-3 crop seasons per cycle. Molecular marker technology allows for faster and more efficient selection, as it is unaffected by environmental factors.  Marker Assisted Recurrent Selection is a key strategy in molecular breeding because it allows for multiple QTLs to control complex traits, unlike Marker Assisted Selection and Marker Assisted Backcrossing
