Evaluation of Eleven Entries of Tomato (Solanum lycopersicum) for Resistance to Bacterial Wilt (Ralstonia solanacearum (E.F. Smith) Yabuuchi et al.,), Powdery Mildew (Oidium neolycopersici) and Late Blight (Phytophthora infestans (Mont de Bary)

Abstract

Eleven entries of tomato namely: Marimar, 39-1, 40-N, 46-N, 42-N, 35-1, CLN17671721, BPI9956, BPI99510, CLN2112, and NSICTm9 were evaluated for resistance to bacterial wilt and other diseases under greenhouse condition. The study was conducted at NPRCRTC and Plant Pathology greenhouse from November 2015 to May 2016. Results revealed that the entry CLN2112 exhibited early symptoms of wilting while CLN 17671721 gave the highest wilt infection compared to the other entries and a percentage disease incidence of 46.66%. All entries were infected with late blight and powdery mildew. The highest marketable fruit was obtained from entry 35-1 with a mean of 2367.50g followed by the entry 46-N with 2092.50g which were significantly higher than the harvest from entries 39-1 and 40-N with a mean ranging from 1348.75-1277.50g.
