| Outline of Final Research Achievements |
It is supposed that a gene of suppression factor in seedless expression exist in pummelo because segregation ratio of seedy : seedless is 3 : 1 in crossing with pummelos while that is 1 : 1 in crossing with mandarins. In this research, the results indicate that a suppression factor in seedless expression is a quantitative trait and two QTLs are detected. This QTLs would be related to the suppression factors in seedless expression. However, it was difficult to develop DNA marker for selection of seedy progeny since the ratio of homogenous allele in pummelos genome was showed very high.
