All species bananas need pollination of some sort to set seed, whether it be self pollination (inbreeding) or pollination by another plant (outbreeding). The species that do this do not belong to any special groups, there are a few in each group that do, from Eumusa there are some forms of M. acuminata subsp. banksii that do it, and from Rhodochlamys M. velutina, M. rubinea and M. mannii (although mannii and rubinea have bisexual flowers, however they do not often self pollinate in cultivation). M. ingens and M. boman have this trait along with M. monticola and Ensete ventricosum.

The moral of the story is yes, they need pollination to set seed.

I know nothing about Helens Hybrid, as it is very new to the market I have not seen any flowers of it so I cannot say weather it self pollinates or really anything about it.
