Abstract
II Youhang No.1 was developed by crossing the good quality three-line male sterile Ⅱ-32A with the restorer line Hang The hybrid rice combination exhibited the desirable characteristics including high and stable yield,wide ecological adaptabilities and high seed production.It has been certified by the crop variety evaluation committees in Fujian in 2001,and subsequently,in China in 2005.This paper presents the breeding process,characteristics,cultivation techniques and seed production of ⅡYouhang No.1.
