Abstract: The aim was to study whether xenia effect existed in Chinese cabbage.Taking 14S116 as female parent and 14S443,14S375,14S120,14S502,14S393,14S536 as male parent,and taking 14S193 as female parent and 14S443,14S125,14S116,14S375,14S531 as male parent,and taking 92S24A as female parent and 8407,72M,DaT511,Da164-2-1,14S126,14S375,Shandong number 4,Jiecai,Da qin 3 as male parent,hybrids were prepared,and silique length,silique width,beak length,shape of seed,seed number of per pod,1000-grain weight,from which mid-parent,heterosis and male effect were acquired.Another,JY3 and JY4,JY5 and JY6,JY19 and JY20,Bre and Xiasheng,92S24 and Xiasheng,14S375 and 14S116 were respectively intercrossed,1000-grain weight seed were determined,and shope of seed and color of seed from some hybrids were observed,from which mid-parent,heterosis and male effect were acquired.The results showed that length and width of the silique,beak length,shape of seed,seed number of per pod,1000-grain weight of F₀ affected by pollen from different male parent were detected.Over-parent heterosis and heterosis were presented.
