Online Published on 14 August, 2024. Abstract The present investigation was carried out to unravel the inheritance of powdery mildew disease (PMD) resistance using two F1 (LGB 752 × DBGV 5 and VBN 6 × LBG17) andtheir corresponding F2segregating populations. Results showed that both the F1 showedresistance and their F2 populations segregated in to 9:3:3:1 ratio, and goodness of fit showed highly significant indicating PMD resistance is controlled by two major dominant genes, which are bi-allelic, non-epistatic, and di-genic in nature.
