F0V

HD 23585 is the F0V dagger type (Garrison94)

Morgan65 lists Rho Gem (HD 58946) as its F0V standard, and classified
four Hyads as F0V or variant: HD 27397, 28294, 28556, & 29375.

Abt68 lists Coma T109 as their F0V standard. 
Cowley69 and Cowley74 listed F0V standards Alf CVn(ft),Gam Vir, Rho Gem
Cowley76 lists Gam Vir as their F0V standard. 
MK43 lists Gam Vir and Eps Cep as their F0V standards.  
Skiff08 flags one star as F0V MK standard: HD 23585 (MK78)

Gray01/03/06 lists only 2 F0V stars. Median HIP colors:
<B-V>(F0V) = 0.295 (+-0.002 sem, +-0.003 stdev; N=2) Gray01/03/06
<V-I>(F0V) = 0.345 (+-0.002 sem, +-0.004 stdev; N=2) Gray01/03/06

# No standard 
MK73 does not list a F0V standard

# dagger standard

  F0V: MK73,MK78,Kennedy83,Keenan85,Garcia89,Gray89,GrayNstars,GrayAtlas
  A9V: Jaschek64,Jaschek78
  No Houk type, probably light reddening (E(B-V) ~ 0.04 mag?)

# Weak Standards
HD 58946 = rho Gem = HR 2852
  F0V:  JM53,Jaschek64,Morgan65,Cowley69(stan),Cowley74(stan),Jaschek78,
  F0V+: Gray89 (MgII 4481A sl wk)
  F0:   Cannon 
  F1V:  Morgan71,Gray03
  F1mA9V: Garrison72(stan)
  F2-3VA S: Kennedy83 
  "A" is a spectroscopic binary (Worley96), so not ideal standard
  B-V = 0.316 (Mermilliod91)
  No Houk type, lit. types disagree a bit, and it's spec binary
  Morgan65 uses rho Gem as the F0V "fundamental classification standard", but then Morgan71 calls its F1V

HD 110379 = gam Vir AB = Porrimma
  F0V: MK43,JM53,Cowley69(stan),Cowley74(stan)
  F1V: Keenan89,Houk99
  F2V: Gray03
  literature ranges from A7V to F2V, i.e. not the best standard
  nearly equal mass binary. Gam Vir and Eps Cep were the F0V standards in MK43. 

HD 211336 = HR 8494 = HIP 109857 = eps Cep
  F0IV: JM53,Jaschek64(most),Barry70,Ortega83,Abt95
  F0V: MK43
  F0V Sr II: Gray01
  F0: Cannon
  A9IV: GrayGarrison89
  B-V = 0.278, Mv=2.09, dMv= -0.33, so only slightly above MS. 
  GrayGarrison89 called "A9IV", but Gray01 called it "F0V Sr II". 
  Virtually everyone agrees on "F0" subtype. All post-JM53 consider it "IV".
  Probably an acceptable secondary standard "F0IV"
