Progress Report Objectives (from AD-416) Phenotypic characterization of 44 PGRU tomato (Solanum lycopersicon) heirloom accessions. Approach (from AD-416) PGRU Solanum lycopersicum (tomato) heirloom accessions will be grown in replicate plots at the Long Island Horticultural Research and Extension Center, Riverhead, NY for phenotypic characterization. Two PGRU SYs and one support staff will travel to the plots for one week in August 2009 to participate in data collection. Septoria leaf spot was the main disease observed. It�s the most common disease observed in organically-produced tomatoes on LI. "Brandywine" and "Aker's West Virginia" were more severely affected than most other varieties. Symptoms were common on "Oxheart", "Howard German", and "Burbank". Fewest symptoms were seen on "VFNT Cherry", "Marglobe", and "Sponzillo"; these were not significantly less severely affected than all other varieties except the two most severely affected ones. Flowers were first observed on 18 June. All varieties had flowers on 13 July. First fruit were observed on 18 June. Some fruit were ripening on 25 July. Marketable yield varied greatly among the varieties evaluated mostly due to the fact there were many different types of tomatoes from cherry tomatoes, to plum, to beefsteak types. The largest fruits were produced from the varieties "Brandywine" and "Aker�s West Virginia" yielding fruit weighing 0.88 and 0.72 lbs per fruit, respectively. "Cherokee Purple", "Oxheart", and "White Queen" each produced fruit weight in at about 0.50 lbs each and the smallest fruits were the cherry types producing fruit at 0.02-0.03 lbs each. There were a few varieties that did not produce acceptable early season marketable yields, totals from the first three harvests on August 19, 26, and September 1, and included the varieties "Brandywine", "Oxheart", "Orange Strawberry", "Tres Cantos" and "Aker�s West Virginia". In comparison, total season marketable yields were greatest for the varieties "Black Plum" and "Roma VF", with both producing more than 7 lbs of fruit per plant. Fruit quality characteristics also varied greatly among the varieties evaluated. Most varieties were rated marketable. "Cherokee Purple", "VNFT Cherry" and "Opalka" were rated as an 8 on a 1-9 scale for overall satisfaction with 1=no satisfaction and 9=great satisfaction. Many of the other varieties were rated 5 or above with a couple varieties rated below 5, which included the varieties "Tainan (AVRDC #6)", "T1003", "T1693" "Principe Borghese", "D�Olivia x Industria", and "Alisa Craig". In terms of taste, the variety "White Queen" was rated as being very acidic while many of the varieties were rated as being slightly sweet, neutral, or slightly acidic. External defects were common in many of the varieties ranging from green shoulder to radial cracking but there were two varieties which stood out as having no recorded external defects: "Sponzillo" and "Orange Strawberry". Additional assessment of fruit quality characteristics was done by cooperators with the SolCAP project. Fruit were also evaluated by 54 additional people, including other LIHREC and CCE staff members, Plant Science Day attendees, organic growers, their workers, and CSA members. Raters looked at a sub-set of varieties. The most popular varieties were Globe, Orange Strawberry, and White Queen. This project is monitored through email and phone calls.
