Summary of Results:

Nine varieties were transplanted on May 30, 2008 at a grower’s location in Celeryville, OH. The experiment was conducted as a randomized complete block design with 4 replications. Plots were double rows, 25 feet long. Eight plants from the middle were harvested to determine yield and quality.

The first harvest was 8 Aug 2008 and the second harvest on 29 Aug 2008. The third harvest was made on 16 Sep. 2008, but after 11 inches of rain over a 10 to12 day period, Phytophthora blight had taken its toll on the field.

The top performing varieties (boxes per acre of extra large + large fruit) in the first harvest were: Revolution and significantly better than other varieties except for PS992 7141. Karisma also produced nearly 200 boxes/A but not significantly better than other varieties except for Palidan and RPP20809 (see Table 1.). The greatest difference was in the Jumbo and Xtra large categories with little difference among varieties in the large size with RPP 20809 having significantly less large size fruit than Revelation and Karisma. The top 3 varieties had 194 to 288 boxes/A of Xtra Large + Large fruit which is a significant improvement from 2007 and similar to previous years.

For total harvest (3), the old standby #9 Paladin was on top but not significantly better than other varieties except RPP 20809. Varieties producing near or in excess of 500 bushel/A of extra + large fruit were Paladin, Revolution, PSS9927141 and Declaration (see table 2). (#3). There was no significant difference in yield among other varieties but in practical terms, yield ranged from 431 boxes/A (Aristotle) to 550 boxes/A (Paladin) (see table 2). Interestingly, the top 3 varieties in 2006 were PX9927141, 9928002 and Paladin (see table 2).

Table 3 shows the percentage of marketable fruit in the large size categories (% marketable large (represents the number of xtra large and large fruit compared to all fruit harvested) for the first harvest and all harvests. Percent marketable represents every size category that can be sold from extra large down to the select category. Revolution, PS992 7141, Karisma and Declaration were the only varieties with 50% or more of its fruit in the larger size categories for the first harvest. For total harvest, there was no significant difference among varieties which ranged from 35 to 44% of their fruit harvested in the marketable large size categories.
