[目的]筛选适宜华北低平原区独特气候特点和种植模式的油葵品种。[方法]通过对引进的新葵10号、S698、S567、新葵22号、新葵20号、S998、S667、S672 8个油葵新品种的生育期、植物学性状、抗性和经济性状的比较,分析鉴定各品种的适应性、丰产性、抗逆性和经济性状。[结果]在参试的8个油葵新品种中,S567和新葵22号综合性状好,增产潜力大,稳产性较好,全生育期较短,经济效益显著,适于在华北低平原区推广种植。[结论]该研究为华北低平原区油葵生产发展提供理论依据。

[Objective] To screen proper new varieties of oil sunflower suitable for the climate characteristics and planting mode of north China. [Method] The biological and economic characters of eight varieties of oil sunflower were introduced,such as Xinkui10,S698,S567,Xinkui22,Xinkui20,S998,S667 and S672. The adaptability,yielding ability,stress resistance and economic character of each variety were identified and analyzed. [Result] Among the eight introduced varieties of oil sunflower,S567 and Xinkui 22 had relatively good comprehensive characters,huge yield-increasing potential,good yield stability,short growth period,and significant economic benefit. Therefore,S567 and Xinkui 22 were suitable for the extension of low plain area of north China. [Conclusion] This research provides theoretical foundation for the production and development of oil sunflower of low plain area in north China.
