why pomato is not used? is this give good yield?

Dear Student,
Please find below the answer to your query

Pomato is a hybrid fruit obtained from tomato and potato. It is small tomato-like fruit, with white flesh, edible either raw or cooked. It is not used commonly because it is produced by grafting which is a difficult process as the potato and tomato stems must be of same thickness for a successful graft.  Another reason is that pomato is genetically sterile and cannot produce viable seeds. So, it cannot be grown by seeds. Yes, the yield of pomato is good.
