摘　　要：宁杂1818属甘蓝型油菜中晚熟品种类型,选自“宁油18×088018”组合,其株高178.73 cm,分枝点较高。一次分枝6.48个,主轴约长60 cm左右,单株角果数257.60个,角果长6~7 cm,果喙较长。每角种子数22.05粒,千粒重4.09g;芥酸含量0.50%,硫苷含量19.71μmol/g,含油量45.54%。国家油菜区域试验结果,平均产量3110.40 kg/hm2,比对照增产4.14%;生产试验结果,宁杂1818比对照增产5.95%。该品种抗病毒病,较抗菌核病,抗倒伏能力强。Ningza 1818, a middle-late mature cabbage-type rape （Brassica napus L.） variety, was developed from the hybrid- ization between Ningyou 18 and 088018. The plant height of Ningza 1818 was 178.73 cm, and its branching point was relatively high. This variety had 6.48 preliminary branches per plant, its main axis length was about 60 cm, the number of pods per plant was 257.60, pod length was 6-7 cm, and pod-mouth was relatively long. The number of seeds per pod was 22.05, and 1000-seed weight was 4.09 g. In its seeds, erucic acid content was 0.50%, glucosinolates content was 19.71 μmol/g, and oil content was 45.54%. In the national regional trials for rape varieties, the average seed yield of Ningza 1818 was 3110.40 kg/hm2, which was 4.14% higher than that of the control variety Qingyou 10. In the production tests for rape varieties, Ningza 1818 obtained 5.95% higher yield than the control. This variety was resistant to virus disease, relatively resistant to stem rot （Sclerotinia sclerotiorum）, and strongly resistant to lodging.
