Abstract
X07eS with eui gene was developed from X07S by 60Co γ-ray irradiation of dried seeds. Allelic test indicated that the mutant X07eS was controlled by eui1 gene. The results showed that the expression of eui gene was independent to the male sterility gene. The plant height and panicle exsertion of X07eS and X07S was not significant difference in the male sterile period, but it was significant difference in the fertile period. The plant height of X07eS was significant increased because of the elongation of uppermost and second internode, as well as the panicle was completely exserted in fertile period. Compared with X07S, the spikelet number, panicle length, spikelet length and length-width ration of X07eS were increased. The stigma vigor of X07eS and X07S were the same, and X07eS was much sensitive to GA3
