Powdery mildew disease in mungbean is caused by the fungus, Erysiphe polygoni D.C. We identified two quantitative trait loci (QTLs) controlling resistance to the disease in a RIL population of 190 $F_7$ lines. The population was developed from the cross between a susceptible cultivar, "Kamphaeng Saen 1" and a resistant line, "VC6468-11-1A". Reaction to the disease was evaluated for resistance in field and greenhouse conditions. Results from analysis of variance revealed that 15 SSR loci on three linkage groups (LG) associated with the resistance. Composite interval mapping consistently identified two QTLs on two LGs, qPMR-1 and qPMR-2, conferring the resistance. qPMR-1 and qPMR-2 accounted for 20.10 and 57.81% of the total variation for plant response to the disease, respectively. Comparison based on common markers used in our and previous studies suggested that qPMR-2 is possibly the same as the major QTL reported earlier using another resistant source. The SSR markers flanking and closely linked to qPMR-1 CEDG282 and CEDGI91) and qPMR-2 (MB-SSR238 and CEDGl66) are useful for marker-assisted selection for mungbean resistance to powdery mildew.

Genetics of the Resistance to Powdery Mildew Disease in Mungbean (Vigna radiata (L.) Wilczek)

Powdery mildew disease caused by the fungus Erysiphe polygoni D.C. is an important disease of mungbean. Loss can be more serious if the disease attacks at seedling stage. In this paper, we report genetics of the resistance to powdery mildew disease in mungbean using a recombinant inbred line (RIL) population derived from a cross between the susceptible parent "KPS1" and the resistant parent "VC6468-11-1A". Five hundred and ninety-two RILs were developed by random descending from $200\;F_2$ plants. The population was evaluated against the fungus in field and greenhouse conditions. The data were analyzed following a nested design for self-pollinating plants to determine genetic heritability of powdery mildew resistance. The severity of the infestation was measured by using disease index (DI) and area under disease progress curve (AUDPC). Both values showed continuous distribution in the RILs. Under field conditions, the narrow-sense heritability of Dr and AUDPC were 0.67 and 0.48, respectively. While under greenhouse conditions, the values were 0.68 and 0.62, respectively. The results suggested that the resistance is quantitatively inherited with high heritability and predominantly additive gene action. To develop powdery mildew-resistant mungbean varieties, the plant breeder can select for resistant lines by using standard selection procedures for self-pollinating crops, viz. pedigree selection, bulk selection, early generation testing, and single-seed descent.
