Abstract: A new soybean cultivar, Đ9, has the advantages of its parental lines: the Rpp2 resistance gene from the male parent (ĐT2000), and early maturation from the female parent (TL7). Đ9 displayed high resistance to soybean rust isolates from Vietnam, short-medium time to maturity, and high grain yield. This cultivar has been released for commercial production in northern Vietnam.
