Multiplication trial of the 49TH IBWSN – Gene-based marker data for marker-assisted selection

The genotypes from the International Bread Wheat Screening Nursery (IBWSN) multiplication trial, which is designed to rapidly assess a large number of advanced generation (F3-F7) lines of spring bread wheat under Mega-environment 1 (ME1) that represents diversity for a wide range of latitudes, climates, day lengths, fertility conditions, water management, and (most importantly) disease conditions, were used for this study.
