摘　　要：2006—2007年在贵州省玉屏县(海拔450 m),对优质杂交香稻黔香优302进行了制种技术研究。根据其双亲的特点和在黔东玉屏县的表现,安排父本3月26日播种,母本4月26日播种,花期相遇良好,确立了适宜的制种技术,并讨论了该杂交稻制种的改进措施。Qianxiangyou 302, a quality aromatic hybrid rice variety, was tested to study its seed production technique in Yuping county, Guizhou from 2006 to 2007. The sowing time of the male and female parent was determined on 26, March and 26, April respectively according to their characteristic and performance in Yuping county and their flowering stages were wellmatched. The results showed that 234.7 kg/667m^2 of seeding yield was obtained under the selected sowing time of male and female parents and other suitable cultivation measures. The paper puts forward some suggestions for raising seeding yield of Qianxiangyou 302 in eastern Guizhou.
