【摘要】 以地谷B为优质亲本与龙特浦B和珍汕97B复交,选育出优质、柱头外露率高的株系,并以此与珍汕97A连续多代成对回交,育成优质不育系T80A.该不育系米质好,不育性稳定,配合力高,柱头外露率高,异交特性好,于2000年7月通过福建省科技厅鉴定.用T80A与亚花1号、明恢86、R527等配组的杂交稻组合T优801、T优8086、T优8027等产量高,米质好,具有较好的推广应用前景.更多还原

【Abstract】 T80A has been developed from the cross Zhenshan 97A/T80B by successive backcrossing to T80B, the plant progeny line with high quality and stigma exertion from the composite cross Longtepu B/Digu B//Zhenshan 97B by pedigree selection. It has characteristics of fine grain quality, stable sterility, high combining ability, high stigma exertion and outcrossing rate. The F1 hybrids such as T80 A /Minhui 86, T80 A /Yahua 1and T80 A /R527 show both high yield and excellent quality and a promising prospect for commercial production.更多还原
