摘要： Through recurrent backcrossing in combination with molecular markerassisted selection (MAS), restorer lines R8006 and R1176 carrying Xa21, a gene having broadspectrum resistance to rice bacterial leaf blight, were selected. By crossing the two lines to CMS line Zhong 9A, two new hybrid rice combinations, Zhongyou 6 and Zhongyou 1176 were developed. The hybrids showed high resistance to diseases, good grain quality and high yielding potential in national and provincial adaptability and yield trials.
