Keywords: 0.05 (p<0.78) and 0.03 (p<0.9) in genotypic and phenotypic selection respectively. The narrow sense heritability for ALS and ANT were 0.97 and 0.95 implying that selection for ALS and ANT can be done at early stage in a segregating population. Correlation, SSR and SCAR marker were used. Marker assisted backcrossing procedure was adopted and inheritances for resistant genes were characterized by using F2 and backcrosses. The Chi-square values showed no significant differences for ALS and ANT, Angular leaf spot (ALS) and Anthracnose (ANT) are important diseases of common bean in Ethiopia. This study was conducted to pyramid resistant genes for ALS and ANT diseases into advanced line and to evaluate isolines against ALS and ANT using marker assi, Phg1+phg2+co14+cbb qtl and Phg-1+co-14+cbb QTL exhibited the lowest mean disease score to the three pathogens indicating both a high degree and a broad spectrum of resistance. The study identified three isolines with all four desirable genes. In general, pyramiding multiple genes for durable resistance using MAS in combination with phenotypic selection is invaluable for breeding program.
