EFFICIENCY BASED ON MARKER ASSISTED SELECTION FOR F2 POPULATION WITH ONE LOCUS MODEL: A SIMULATION STUDY

Simulation study was done to evaluate QTL mapping and selection efficiency of molecular markers utilisation in the F2 population. The simulation started with formulating genetic configuration which consists chromosome maps models. Genetic model for diploid individuals is a two alleles each locus. that used mathematical additive, dominance, interactions different effects at locus, maximum interaction occurs between loci (digenic). constructed by using single locus model, multiple model. effect sample size, heritability, marker density observed. Three analyse position, i.e. regression, interval (IM) composite (CIM). Several parameters were specified this study: variability coefficient (GVC=15%), population mean (μ=10), epistasis variance ratio (f=0.1), dominance additive (r=0.25), AA:AD:DD 3:2:1 gene action, its interaction. first last located edge 150 cM chromosome. distance equal. Haldane’s map function simulation. performed Package on “R” software. With heritability 0.2, required size indicate associated 50 level higher than phenotypic screening on. Efficiency based (Em) (d) follows “reciprocal quadratic” function. phenotype (Ef) favourable traits function.Keywords: efficiency, markers, QTL,
