2001—2010年上海市油菜区域试验参试品种产量和品质分析

Analysis of yields and qualities of various varieties in Shanghai regional rape tests between 2001 and 2010

根据2001-2010年上海市油菜品种区域试验资料,对参试品种、产量和品质进行了分析。结果表明:每年区试参试的杂交种数量逐步上升,区试参试品种比对照种单产年平均增产5.83%,特别是杂交组合比常规品种在产量水平上具有明显优势。区试参试品种含油率为42%～45%,常规品种平均含油率比杂交组合高1.43%。参试品种双低指标符合国家标准,芥酸含量常规品种和杂交组合相当,硫苷含量杂交组合比常规品种高14.75%。

The rape varieties in Shanghai regional rape tests between 2001 -2010 were analyzed in terms of variety number ,rapeseed yield and quality. The results showed that the number of tested hy- brid varieties increased annually,the average yield of tested varieties increased annually by 5.83% o- ver the control varieties,and the cross combinations had an obvious yield advantage over the ordinary cultivars. The oil contents of tested varieties were 42% -45 %, and the average oil content of ordinary cultivars was 1.43% higher than that of cross combinations. The tested varieties met the national standards of erucic acid and glucosinolate contents,and both ordinary cultivars and cross combinations were equivalent in erucic acid content,but the cross combinations＇ glucosinolate content was 14.75% higher than the ordinary cultivars＇.
