摘　　要：为选育携带标记性状的高含油量双低油菜显性核不育恢复系,本研究以携带花叶、高含油量、显性核不育恢复基因等不同性状的油菜种质为亲本,通过复合杂交技术结合定向筛选,获得花叶、高含油量且早熟的双低甘蓝型油菜显性核不育恢复系4061R。田间调查和品质分析表明:恢复系4061R叶型为花叶,生育期为210 d,株高156.2 cm,每角粒数20.1粒,单株角果数300.2个,千粒重4.3 g。在上海种植密度为18.5×10^(4)株/hm^(2)的条件下,4061R实际产量为2219.7 kg/hm^(2);利用近红外反射光谱法检测其种子含油量为50.6%、芥酸含量为0.7%,硫代葡萄糖苷含量为19.6μmol/g,该恢复系综合性状较为理想。To breed high oil and double-low(low erucic acid and low glucosinolates)restorer with morphological marker for dominant genic male sterile in rapeseed,breeding materials with lobed-leaf,high oil content or restoring gene were utilized as parents.The restorer line 4061R with lobed-leaf,high oil-content and precocious feature was obtained through composite-crossing combined with directional selection.The field test and quality analysis showed that 4061R had lobed leaves with total growth period of 210 d,plant height of 156.2 cm,seed number per siliqua of 20.1,silique numbers of per plant of 300.2,1000-seed weight of~4.3 g.In Shanghai,yield of 2219.7 kg/hm^(2) was obtained under 18.5×10^(4) plants/hm^(2).The restorer seed oil-content was 50.6%,with erucic acid 0.7%,and glucosinolate 19.6μmol/g detected by near-infrared reflectance spectroscopy.Thus 4061R was an ideal restorer line with better comprehensive properties.
