近年来我国冬油菜新品种的品质性状分析

Analysis of Quality Traits of New Winter Rape Varieties in Recent Years in China

对全国冬油菜区域试验的四大组（长江上、中、下游和黄淮地区）1987~2009年的参试新品种的主要品质性状进行了统计分析。结果表明,我国冬油菜新品种平均芥酸和硫甙含量显著下降,而近几年来新品种含油量逐渐上升。预计今后一段时间平均芥酸含量将可能接近于零,新品种含油量将进一步提高,到2015～2020年,全国冬油菜新品种平均含油量有望超过45%。

There were four major groups of regional trials for winter type rape varieties in China.In this study,the analysis of main quality traits of the tested new varieties in 1987~2009 would be showed by the charts.The result showed that erucic acid and glucosinolate contents were significantly decreased,and the average oil content rose up slightly in the recent years.In the foreseeable future,the average content of erucic acid would be close to zero slowly,while the average oil content would increase rapidly.By 2015 to 2020,the average oil content would exceed 45%.
