The results showed that single fruit weight , fruit diameter , fruit height , fruit shape index (weight/diameter) , peel thickness , fresh seed number , fresh seed weight , seed ratios of fresh fruit or seed number per kg were different to some extent. The fruit diameter , fresh seed weight , seed ratios of fresh fruit and seed number per kg between Cenxi soft-branch No.2 and Cenxi soft-branch No.3 showed extremely signifi幽 cant differences. On the whole , there were less differences between the cultivation areas of Nanning and Cenxi , but more between Sanjiang and the two
