Abstract
The characters of pod with different seed number in sterile line of hybrid rape Youyan 5 were studied.The results showed as follows.The seed number per pod was related to the pod size,and the seed weight per pod were effected by each components of pod.With the seed number per pod increasing,the bearing percentage of pod,seed /cm 2,seed weight per pod,yielding capacity(mg/cm 2),economic coefficient,total shell weight per pod,biological yield per pod and the rate of contribution to yield increased regularly,but 1000 grain weight and percentage of pod reduced regularly.The Proportion of radish like pod to effective pod number was about 2/5,the rate of contribution to yield was about 1/10.Except to 1000 grain weight,all characters for normal pods were superior to that of radish like pod
