分子标记和近红外技术辅助选育高油酸花生新品种花育66

Development of a New High-oleic Peanut Cultivar Huayu 662by Using Molecular Marker Aided Selection and NIRS

为选育高油酸、高产花生新品种,以高油酸亲本CTWE为父本、高蔗糖亲本06-I8B4为母本搭配杂交组合,结合近红外分析技术与分子标记辅助选择技术育成FAD2B/FAD2A双突变高油酸小花生新品种花育662。该品种油酸含量80.8%,油亚比29.92,出米率高达79.7%。在2012年山东省花生研究所莱西试验农场产量试验中,子仁产量5 132.4 kg·hm-2,略低于对照品种花育33号5 224.5kg·hm-2的产量水平,2014年通过安徽省品种鉴定。本研究为加速高油酸花生育种进程提供了良好的技术方法。

To breed new peanut variety with high-oleic and high-yield, a hybridized combination was made between 06-I8B4 （high sucrose, female parent） and CTWE （high-oleic, male parent）. Using molecular marker technology coupled with NIRS （Near infrared reflectance spectroscopy） assisted selection, Huayu 662, a new high-oleic peanut variety with FAD2A/FAD2B double mutation was finally developed. The seed of Huayu 662 contained 80.8% oleic acid in its total fatty acids. The oleate/linoleate ratio of the cultivar was as high as 29.92. The shelling outturn was 79.7%. In 2012, Huayu 662 produced a kernel yield of 5 132.42 kg·hm^-2, comparable to the control Huayu 33 output of 5224.5 kg·hm^-2 in yield test on the SPRI Experimental Farm in Laixi, Qingdao, China. The cultivar was approved for release in Anhui province for commercial production in 2014. The research provided a good technical solution to speed up the breeding process of new high-oleic peanuts..
