Continuing the project described by Kato et al. (2009, PASJ, 61, S395,arXiv/0905.1757), we collected times of superhump maxima for 102 SU UMa-typedwarf novae observed mainly during the 2017 season and characterized theseobjects. WZ Sge-type stars identified in this study are PT And, ASASSN-17ei,ASASSN-17el, ASASSN-17es, ASASSN-17fn, ASASSN-17fz, ASASSN-17hw, ASASSN-17kd,ASASSN-17la, PNV J20205397+2508145 and TCP J00332502-3518565. We obtained newmass ratios for 7 objects using growing superhumps (stage A). ASASSN-17gf is anEI Psc-type object below the period minimum. CRTS J080941.3+171528 and DDE 51are objects in the period gap and both showed long-lasting phase of stage Asuperhumps. We also summarized the recent advances in understanding of SUUMa-type and WZ Sge-type dwarf novae.
