Development of cytoplasmic male sterile （CMS） lines with elongated uppermost internode （EUI） trait provides a genetic option to eliminate the use of GA3 in hybrid rice. During the past two decades, extensive work has been carried out on the subject that resulted in identification of several mutants with EUI trait for use in developing cytoplasmic/thermo-sensitive genic male-sterile lines with complete panicle exsertion （Okuno and Kawai, 1978; Rutger and Carnahan, 1981; Shen et al., 1987; Yang et al., 2000; 2002; Gangashetti et al., 2004）. Two recessive genes （eui-1 and eui-2） mapped on chromosome 5 and 10 respectively have so far been reported to control the internode elongation in rice （Librojo and Khush, 1986; Yang et al., 2001; Ma et al., 2004）. Considerable progress has been made in China in exploiting ＇eur gene for development of hybrid rice parental lines （Yang et al., 2000; 2002; Zhang et al., 2002）.
