Analysis of Agronomic Characters and Seed Fatty Acid Compositions of Wild Rapeseed from Different Sources
This study identified the field performance characters of 20 wild rape resources from different sources,detected the fatty acid composition and accumulation mode of wild rape seeds by GC-MS(gas chromatograohy-mass spectrometry),and clarified the correlation between fatty acids and seed and plant apparent characters,so as to provide a scientific theoretical basis for further studying the correlation between phenotype and quality of wild rape resources.The results showed that 48 variation types were detected in 20 wild rape seed and plant characters.Except that the phenotypes of 8 basic plant characters were consistent,the other characters were significantly dif-ferent.A total of 17 kinds of fatty acids were detected,including 8 kinds of saturated fatty acids and 9 kinds of un-saturated fatty acids.There were significant differences in the accumulation of various fatty acids in different wild rape resources.There is a certain correlation between fatty acid content and multiple seed or plant characters,and there is a significant correlation between seed shape and multiple fatty acids,γ-Linolenic acid was significantly correlated with many characters.According to the fatty acid accumulation model,the 20 wild rape resources can be divided into three provenance clusters.The relative contents of 7 fatty acids in wild rape V205 seeds were sig-nificantly higher than those of other varieties.The above conclusions can provide a scientific basis for cultivating new rape varieties with reasonable fatty acid structure.
