Abstract

Iteyou3381,developed from the fine quality CMS line Ilongtepu A as the female parent and the new restorer line Longhui3381 as the male parent by the Institute of Agricultural Science of Longyan,is a new three-line indica hybrid rice combination for late cropping season.It has the characteristics of good grain quality,high and stable yield,suitable maturity and wide adaptability.It had a yield of 471.89kg/667㎡ on average,6.03% higher than that of the check hybrid Shanyou63,in two years(2003-2004)of Fujian Regional Trials.It was registered and released by the Crop Variety Approval Committee of Fujian in January,2006.The breeding procedure of Iteyou3881 and its major characteristics,cultivation and hybrid seed production techniques are introduced in this paper.
