Abstract
Rapeseed mustard is the third important oilseed crop in the world after soybean (Glycine max) and palm (Elaeis guineensis Jacq.) and globally, India account for 19.29% and 11.12% of the total acreage and production respectively. The mustard crop suffers from various biotic and abiotic stresses. Among the different pests and diseases affecting this crop, mustard aphid, Lipaphis erysimi Kalt is the major limiting factor for qualitative as well as quantitative production of mustard, which infests the crops right from vegetative stage to pod stage and accounts for 27% to 69% of yield loss with 15% reduction in its oil content. In this context, breeding for aphid resistance and identification of molecular markers for this trait could be a valuable approach for development of resistant genotype.
