Notes and observations:

Thermotherapy to remove tristeza. Hassaku is probably of pummelo-mandarin parentage with pummelo predominant.

Description from The Citrus Industry Vol. 1 (1967):

"Fruit medium-large (9-10 cm in diameter), slightly oblate; both ends somewhat depressed; seedy and monoembryonic.  Rind color orange-yellow; medium-thick; surface somewhat coarsely pebbled; moderately adherent.  Segments numerous; axis large and semi-hollow at maturity.  Flesh color light yellow; somewhat coarse-grained; lacking in juice; flavor good.  Early midseason in maturity and stores only moderately well. 
      Tree vigorous, upright, virtually thornless; leaves large and pummelo-like, but petiole wings narrower, approaching sweet orange.
      Hassaku is said to have originated as a chance seedling in Hiroshma Prefecture, Japan.  It was noted and named in 1860, but was not propagated and planted commercially until about 1925.  In 1964, Japanese planting was reportedly in excess of 2,500 acres, mostly in the prefecture of its origin.  During the 1960's, however, it has been planted increasingly elsewhere. 
      Its characteristic strongly suggest pummelo-mandarin parentage with pummelo predominant."
