<br/>TRUONG HOAI XUAN, University of the Philippines at Los Bafios, June 1981. Characterization and Identification of Tomato Viruses and Virus Strains in Five Locations in the Philippines, and their Control. Major Professors: Dante A. Benigno.<br/><br/>The viruses and virus strains naturally occurring in tomatoes in five locations in the Philippines were identified through indicator plants, modes of transmission, physical properties, electron microscopy, and serology. <br/><br/>From the nine different disease~types collected, eleven virus strains, belonging to three virus groups, were isolated. These groups are tobamovirus, cucumovirus ené potyvirus. In this tobamovirus group there were six tomato mosaic virus strains identified.<br/><br/>These are ToMV-0O, THV-U6, ToMV-A, ToMV-W, ToMV-GY, and ToMV-YF, The lost three strains are new strains and reported for the first time. Two str:ins were found in the cucumovirus group (CHV-O0 and CMV-Y), also with the potyvirus group (FVv-O severe and FVY¥-O mild). One distinct virus, but a member of the potyvirus group,<br/>Wes was also isolated and was identified as the severe strain of tobacco etch virus (TZV-S). TokV and its strains were isolated from such<br/><br/>| disease-types as green mosaic (ToMV-~0), yellow mosaic (ToMV~A, ToMV-GY, THV-U6, ToMV-YF), and white mosaic (ToMV--W), PVY and its strains were isolated from leaf curl diseases and TEV-S from mild leaf distortion.<br/><br/>The effects of weather, location end varieties on the prevalence and severity of these viruses and their aphid vectors were also determined. The effects of ChV-Y on yield of four tomato varieties (Marikit, . VC9-1, VC48-1, and VC1i1-1), likewise, were established. At 30% infection, there was a corresponding yield loss of 50% in 4 tomato varieties.<br/><br/>Control. of ToMV-A by seed treatment and use of attenuated strain were tried. Both methods were found to be effective. The control of the aphid vectors of CMV and PVY by means of granular and emulsifiable insecticides were compared. Their efficacy varied with the varieties, however, the best insecticide-variety combination wes Thiodean x Marikit variety.<br/> |
