Abstract The differences of seed yield and component factors among dominant genic male sterile line DGMS02-12，cytoplasmic male sterile line CMSR302-12 and inbred line of cabbage（Brassica oleracea var. capitata L．）02-12 were studied．The results showed that the differences of seed yield per plant and plot yield between DGMS02-12 and CMSR302-12 were significant．The whole plant valid siliqua and seeds per siliqua were the main factors for the differences of seed yield between these two male sterile lines of cabbage．The seed yield at the 1st branch account for more than 80% of per plant seed yield，and there were significantly positive correlations and high path coefficient between seed yield and seeds per siliqua and the valid siliqua at the 1st branch．
