摘　　要：在盆栽条件下,研究Eruca vesicaria （L.） Cav. subsps. vesicaria,Eruca vesicaria （L.） Cav. subsps. sativa和Eruca vesicaria （L.） Cav. subsps. pinnatifida3个不同芸芥亚种的植物学形态特征和农艺性状。结果表明3个亚种形态特征存在较大差异。Eruca vesicaria （L.） Cav. subsps. vesicaria的叶、薹茎、角果上都密被刺毛,成熟期较一致,且不易落粒,生育期90-100 d;而Eruca vesicaria （L.） Cav. subsps. pinatifida薹茎基部密被刺毛而上部较少,种子极小,千粒重0.25 g,且易落粒;Eruca vesicaria （L.） Cav. subsps. sativa亚种,角果较长,表面被刺毛或无刺毛,不同材料间生育期差异较大。不同亚种的农艺性状也存在较大差异。Three different subspecies of Yunjie,Eruca vesicaria（L.） Cav.subsps.vesicaria,Eruca vesicaria（L.） Cav.subsps.sativa and Eruca vesicaria（L.） Cav.subsps.pinnatifida were studied on their botany morphological characters and agronomic traits.The results indicated that three subspecies are obvious differences on morphological characters.Eruca vesicaria（L.） Cav.subsps.vesicaria,their leaf,stem and silicle are all covered densely with bristle,the mature period is consistent,also difficult pod shatter,growth period is 90-100 d,Eruca vesicaria（L.） Cav.subsps.pinnatifida,there are more bristle on their base-stem than upside stem,the seed is smallest,the 1000-seed weight is 0.25g,also easy pod shatter,Eruca vesicaria（L.） Cav.subsps.sativa,the silicle is long and it＇s surface is smooth or with the bristle,the growth period is different among the different materials.The different subspecies＇ agronomic traits also have the significant differences.
