摘　　要：[目的]为了选育适应性更好、优质、丰产的杂交油菜品种。[方法]采用杂交转育方法,以黄子双低隐性核不育系02A为母本、双低恢复系41R为父本配制杂交组合宝油717,介绍其主要特征特性,并对其应用进行评价。[结果]该品种具有高油、丰产等特性。于2007年开始参加贵州省油菜研究所的预备试验、比较试验,表现优良,2010年选送参加陕西省油菜区域试验。2010～2012年陕西省区域试验中,两年共计10点次,有9个点产油量增加,增产点次率90.0%,平均产量2 842.50 kg/hm2,较对照秦优7号增产3.41%,平均产油量1 236.15 kg/hm2,较对照秦优7号增产7.62%。两年品质分析,芥酸含量平均为0.51%(2011年为0.29%,2012年为0.72%),硫苷含量平均为35.22μmol/g(饼)[2011年为37.15μmol/g(饼),2012年为33.29μmol/g(饼)],含油量平均为47.34%(2011年为46.12%,2012年为48.55%)。于2013年6月通过陕西省油菜区域试验并获审定。[结论]该研究可为今后油菜育种提供参考。[Objective] The aim was to breed hybrid rape variety with better adaptability,high yield and good quality.[Method] Baoyou 717 was bred by taking yellow seed with double low recessive genic male sterile line 02A as female parent and double low restorer 41R as male parent through hybrid commercial method,then introduced its main characteristics and evaluated its application.[Result] Baoyou 717 had characteristics of high oil content and high yield.It showed better during preliminary test and comparison test of Guizhou Province Rape Institute in 2007,and it joined the Shaanxi Province rape regional test in 2010.During Shaanxi Province regional test in 2010-2012,oil production of 9 test points increased and the production increasing point rate was 90.0％,and the average yield was 2842.50 kg/hm2 and increased 3.42％ comparing with that of the control Qinyou No.7,and the average oil production was 1 236.15 kg/hm2 and increased 7.62％ comparing with that of the control Qinyou No.7.The 2-year quality analysis results showed that the average erucic acid content was 0.51％ （0.29％ in 2011,0.72％ in 2012）,the average glucosinolate content was 35.22 μmol/g（cake） [37.15 μmol/g （cake） in 2011,33.29 μmol/g （cake） in 2012],the average oilcontent was 47.34％ （46.12％ in 2011,48.55％ in 2012）.It accessed Shaanxi Province Regional Test in June,2013 and approved.[Conclusion] The study provides a reference for rape breeding in future.
