黄河三角洲盐碱地适宜品种(系)油菜筛选

Selection of Rape Cultivars(Lines) Suitable for Cultivation in Saline-alkali Land in the Yellow River Delta

为了筛选出丰产性好,生育期短,综合性状良好并且适宜黄河三角洲盐碱地种植的油菜优良品种,本文对14个品种(系)油菜的生育期、越冬率、干物质、农艺性状和产量性状进行比较分析。结果表明,1401、1403和2014P8 25三个品系的生育期适宜,越冬率相对较高,干物质含量高且经济性状良好,折合产量高,优于其他品种(系)油菜,其中1401产量最高为2431.32kg·hm^(-2),1403和2014P8 25分别为2041.9kg·hm^(-2)、1899.69kg·hm^(-2),可以在黄河三角洲盐碱地适当推广种植。

In order to select rape cultivars with high yield, short growth period, good comprehensive character, and suitable for cultivation in saline-alkali land in the Yellow River Delta, China,14 cultivars（lines） were evaluated with growth period, overwintering percentage, dry biomass, agronomic characters, and yield traits in the present test. The results showed that there were three cultivars（lines）： 1401, 1403 and 2014 P8 25, which were better than other rapeseed cultivars（lines） in overwintering percentage, dry biomass and economic character, andtheir yield was higher than that of other rapeseed cultivars（lines）. The yield of 1401was the highest, 2431.32 kg·hm -2 ,while 1403 and 2014 P8 25’s were 2041.9 kg·hm -2 and 1899.69 kg·hm -2 , respectively. All the three could be popularized in saline-alkali land of the Yellow River Delta.
