Multiple major QTL lead to stable yield performance of rice cultivars across varying drought intensities por Dixit, Shalabh, Singh, Anshuman, Cruz, Ma Teresa Sta, Maturan, Paul T., Amante, Modesto, Kumar, Arvind

“…Production in rainfed areas is affected in particular by drought events, as these areas are commonly planted to high-yielding drought-susceptible rice (Oryza sativa L.) varieties. The use of bulk segregant analysis (BSA), taking grain yield (GY) as a selection criterion, has resulted in the identification of several large-effect QTL. …”
