经分析研究，初步探明我省近年来征集的油菜地方品种含油量、蛋白质、硫甙、脂肪酸等主要品质性状表现。品种品质性状频率分布呈正态、趋正态和偏态分布，其中芥菜型品种品质性状频率分布呈正态、趋正态分布的较多（占６０％）。而白菜型品种品质性状频率分布呈偏态分布的较多（占６０％）。品质性状之间的相关性因品种类型而异，白菜型品种品质性状间呈正相关的较多（６７％），而芥菜型品种品质性状之间呈负相关的较多（占６２％）。 Through the analysis and research, we initially ascertain the performance of oilseeds, protein, glucosinolates, fatty acids and other major quality traits of rapeseed cultivars collected in our province in recent years. The frequency distribution of quality traits showed normal, normal and skewed distributions. The frequency distribution of quality traits of B. juncea varieties was normal and normal distribution (60%). The frequency distribution of quality traits of cabbage varieties showed a skewed distribution (60%). The correlation between the quality traits varies with the type of the cultivars. The quality traits of the cabbage varieties are positively correlated (67%), while the quality traits of the Brassica juncea varieties are negatively correlated (62%).
