摘要
以扬稻6号为母本、江西东乡野生稻为父本进行杂交、回交,育成野栽交强优恢复系F302,再与两系不育系Y58S配组育成高产、优质、适应范围广的两系杂交中籼稻新组合Y两优302,于2008年通过湖南省审定,2010年通过国家审定。介绍了该组合的选育经过、主要特征特性、栽培及制种技术要点。
F302,developed from the cross of Yangdao 6/Jiangxi Dongxiang Wild Rice and its backcross to Yangdao 6,is a strong restorer line in rice.Y Liangyou 302,derived from Y58S,a PTGMS line,and F302,is a new two-line medium indica hybrid rice combination with high-yielding ability,good grain quality and wide adaptability.It was certified and released for commercial production by the Hunan Provincial and the National Crop Variety Appraisal Committees in 2008 and 2010,respectively.The breeding procedure and major characteristics of Y Liangyou 302 and the key points of its grain production and hybrid seed production techniques were introduced in the paper.
