SENSHU

Synonym: None

Parentage: Toko x Fuji

Color: Pink stripe over green

Harvest: Mid to late August

Fruit: Small to medium, round to oblate, and regular. The cavity is shallow and quite open (obtuse) with a short to medium stem, generally thick and often enlarged at the end. The basin is shallow, opened, often ridged with a small closed calyx. The lenticels are light tan colored, distinct and may be enlarged and irregular shaped. Fruit color is often quite poor in this area with less than 50% of the surface showing pink color. Color is only medium bright and often light or muddy pink. Senshu resembles Fuji. The flesh is above average in firmness and juiciness, but only moderately crisp. Flavor at maturity is slightly sweet and bland. Less mature fruit (S.I. ≤ 3) can be subacid to tart while fruit at advanced maturity (S.I. ≥ 6) have a fair balance of acid and sugar but are generally soft. Storage data is limited on this cultivar, to-date, but it appears to have capability of 3 months storage or more. Shelf life is unknown at this location, but it has been reported elsewhere to compare with Fuji.  Low susceptibility to plum curculio, tufted apple bud moth and redbanded leafroller.  Moderately susceptible to tarnished plant bug.  Highly susceptible to codling moth and oriental fruit moth.

Tree: Moderately vigorous, somewhat spreading, and open. Productivity has been moderate to poorer. Bloom is mid-season to somewhat later. Trees are moderately susceptible to scab and cedar apple rust and resistant to powdery mildew.  Moderately susceptible to rosy apple aphid, European red mite, Japanese beetle and spotted tentiform leafminer.  Highly susceptible to white apple leafhopper.

Market Potential: Limited
