摘　　要：鄂粳杂１号夏制双亲出叶特点为：营养生长期出叶速度是母本快父本慢，生殖生长期是父本快母本慢；父母本同时进入幼穗分化和同时齐穗可实现父母本盛花相遇。In this paper,the observation was conducted for leafing,ear bearing,earing and flowering of the parents of EGengZa No1,a kind of twoline Japonica hybrid rice in summerseedproduction for two years.The result shows:Leafing characteristics of the parents are that the female parents' leaves grow out faster than those of male parents' during vegetative growth,but slower than the male parents' during reproductive growth.And if both of the parents start to go into youngear differentiation at the same time and ear fully too,their full flowering stages may meet fully each other.
