Breeding of Brassica napus Cultivar Shuangyou 092 with High Oil Content and Its Fine-quality and High-yield Cultural Techniques

Shuangyou 092, a Brassica napus cultivar with high oil content, high quality and high yield, was bred by Institute of Industrial Crops of Henan Academy of Agricultural Sciences with Zhongshuang 9 as female parent, and the cytoplasmic male sterility maintainer line 32B as male parent. It was registered and released in 2014. The average yield was 2 858.5 kg/hm^2 in Henan province regional test of high quality, 12.43% higher than the check variety Fengyou 9 in 2010-2011 and 2011-2012. Its yield was 3 478.8 kg/ha in Henan Province productive test of high quality,9.52% higher than the check variety Fengyou 9 in 2012-2013. According to the test results in 2011-2012 and 2012-2013, the seeds quality of Shuangyou 092 was very good with near zero erucic acid （0.0%, 0.1%） in fat acid, 17.19 μmol/g and 19.78 μmol/g glucosinolates in its meal, the oil content of 46.60% and 45.76%. The cultivar was resistant （tolerant） to Sclerotinia, virus diseases, cold, and lodging. Its high yield and high quality can be obtained by planting in large scale, sowing at right time, rational close planting, balancing fertilizer and harvesting at right time.

高含油量油菜杂交种双油092的选育及保优高产栽培技术

双油092是河南省农业科学院经济作物研究所以中双9号为母本、细胞质雄性不育保持系32B为父本进行杂交选育的甘蓝型油菜新品种,2014年通过河南省农作物品种审定委员会审定。双油092在2010—2011、2011—2012年度河南省油菜品种区域试验中平均产量2 858.5 kg/hm2,比丰油9号(对照)增产12.43%;在2012—2013河南省油菜品种生产试验中,平均产量3 478.8 kg/hm2,比对照增产9.52%。双油092品质优良,含油量高,经检测,2011—2012、2012—2013年度双油092芥酸含量分别为0.0%、0.1%,硫苷含量分别为17.19μmol/g、19.78μmol/g,含油量分别为46.60%、45.76%。该品种抗(耐)菌核病、病毒病,抗寒、抗倒。规模种植、适期播种、合理密植、平衡施肥、适时收获等技术是双油092获取高产和保持优良品质的关键栽培措施。
