EMS诱变对北方白菜型冬油菜农艺性状与品质的影响
Effect of ethyl methane sulphonate on agronomic traits and quality of winter rapeseed in North China
摘要
Abstract
In order to explore ethyl methane sulphonate(EMS)mutagenesis on agronomic traits and qualities in winter rapeseed(Brassica rapa L.),and to enrich germplasm of winter rapeseed in north China,Longyou 7 was treated with ethyl methane sulfonate(EMS)at different concentrations(0,0.3%,0.6%,0.9%,1.2%).Morphological characteristics in M1and influence of agronomic traits and qualities of M2were measured.The result showed that EMS mutagenesis on winter rapeseed produced abundant variation,which included leaves appear chimerism bleaching,petals albino,the female and stamens deformity.The height,length of main inflorescence,pods of main inflorescence,the pods per plant,pod length,seeds per pod,1000-seed weight,all of these decreased significantly except the number of branches.In addition large variation produced in fatty acid content.Screening resulted in three plants with higher oleic acid content and low erucic acid content in M2,and one mutant with low glucosinolates content(21.97 μmol·g-1). Proper EMS concentration is suggested as being 0.3% ~0.6%,and the treating time is 6 h.关键词
