高含油量油菜新品种杂双5号的选育

Breeding of Brassica napus Cultivar Zashuang No.5 with High Oil Content

杂双5号是河南省农业科学院经济作物研究所选育的甘蓝型油菜新品种。它是以88A作母本,以98143做父本配制而成的细胞质雄性不育三系杂种。杂双5号具有高含油量、品质优良、抗病、抗倒伏、丰产性突出、稳产性好、适应性广等优点。在2 a河南省油菜区域试验中,平均产量2 866.35 kg/hm2,比对照杂98009增产8.73%;在河南省油菜生产试验中,杂双5号平均产量3 079.65 kg/hm2,比对照杂98009增产15.89%。杂双5号种子芥酸含量0.15%,硫苷含量25.68μmol/g,达到国家双低油菜标准;含油量46.98%,属高含油量品种。杂双5号2008年通过河南省农作物品种审定委员会审定,是一个极具推广应用前景的优良品种。此外,介绍了杂双5号的高产保优栽培技术。

Zashuang No.5,possessed high oil content,high quality,high yield,resistant to virus disease,tolerance to Sclerotinia sclerotiorum and extensive adaptability,was bred by Industrial Crops Research Institute,Henan Academy of Agricultural Sciences.It was a CMS ＂three-line＂ hybrid rapeseed bred by crossing 88A as female parent and 98143 as male parent.The average yield was 2866.35kg/hm2 in Henan province regional test and showed 8.73% higher than the check variety Za 98009.Its yield was 3079.65 kg/hm2 in Henan province productive regional test and showed 15.89% higher than the check variety Za 98009.The seed quality was very good with erucic acid near zero（0.15%）,glucosinolates 25.68μmol/g,and oil content up to 46.98%.It was registered and released in 2008.Zashuang No.5 was a excellent cultivar of extensive use in agricultural production.This paper also instroduced the cultivation technology of Zashuang No.5.
