Abstract

Fruits of tomato (Lycopersicon esculentum Mill) picked at full vine-ripened stage had significantly thicker fruit walls than those harvested at the mature-green stage. No increase in pericarp thickness occurs after fruit detachment from the vine. Fruit wall thickness showed no significant response to accelerated ripening with (2-chloroethyl)phosphonic acid (ethephon).

Abstract

Two Arkansas breeding lines, 2 USDA breeding lines, and 2 commercial cultivars were evaluated for resistance to fruit rot caused by Rhizoctonia solani Kuehn. Each line or cultivar was field evaluated for the percentage of rot of fruit touching the ground and for yield. Arkansas breeding lines and USDA breeding line 79B 888-3 had the lowest percentage of rot and the highest yield, whereas the commercial cultivars and USDA 79B 823-3 had the highest percentages of rot and the lowest yields. The use of Ethephon at 500 ppm significantly decreased the percentage of rot in the field and increased yield.
