Genealogical and schematic diagram of breeding for ‘Drimi2ho’. ‘Drimi2ho’ was breeding for the purpose of developing a new rice cultivar that is resistant to (BPH, Nilaparvata lugens stal), has excellent grain and eating quality and has high cultivation stability. ‘Samgang’ has the BPH resistance gene Bph1 derived from Indica, and ‘Nagdong’ has excellent quality. Lines derived by crossing ‘Samgang’ and ‘Nagdong’ were anther cultured to select ‘SNDH39’, which is resistant to various pest or viral diseases, including BPH, and has excellent agricultural characteristics in the field. ‘SNDH39’ was backcrossed 3 times with ‘Junam’ with excellent quality. In addition, ‘SNJB8-16-3-B’, which is resistant to major pests including BPH and has excellent quality, was selected and finally named ‘Drimi2ho’.
