Pedigree diagram of ‘Drimi4ho’. Drimi4ho’ was derived from the mutant group by backcrossing ‘P47’ with a large embryo size and excellent various agronomic traits in the field and ‘Junam’ with high-quality and high yield three times. In addition, lines with excellent agricultural characteristics and resistance to various pests were continuously selected in the field. The selected line, ‘P47JB-86-1-B’, was finally named ‘Drimi4ho’ after going through OYT, RYT, and LAT. OYT: Observation yield trial, RYT: Replicated yield trial, LAT: Local adaptability test.
