高含油量油菜新品种杂双5号的选育

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。

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

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.
