A new azuki bean variety ‘Saegil’ (Vigna angularis Ohwi & Ohashi) was developed at the National Institute of Crop Science (NICS) in Milyang in 2007. It was developed from the cross between ‘IT189400’ and ‘SA8412’. In 2004, a promising line, which has the characteristics of early ripening, large grain, and disease and stress resistance, was selected and designated as the name of ‘Milyang 1’. ‘Milyang 1’ showed high yielding and good grain quality at the regional adaption yield trials for three years. ‘Milyang 1’ was released to new azuki-bean variety as the name of ‘Saegil’. ‘Saegil’ showed 3 to 6 days early ripening than that of ‘Choungjoo’. Its 100 grain weight is about 18.1 g showing 1.2 g heavier than that of ‘Choungjoo’. The yield potential of this variety was 141 kg per 10a at the nationwide regions.
