SCREENING OF SOME TOMATO ENTRIES AGAINST LEAF CURL DISEASE

Abstract

An experiment was conducted to screen some tomato entries against leaf curl disease caused by Tomato yellow leaf curl virus (TYLCV) & Tomato leaf curl virus (ToLCV). The experiment was conducted during November 2014 to April 2015 at Regional Agricultural Research Station of Bangladesh Agricultural Research Institute (BARI) at Akbarpur, Moulvibazar. Twenty Nine tomato lines namely GPT-009, GPT-011, GPT-015, GPT-017, SL-011, SL-012, China cherry, GWT-043, GWT-052, GBT-037, GBT-053, GBT-056, SL 001, SL-003, SL-008, SL-009, SL-010, W11

Hybrid-1, W11 Hybrid-33, W11 Hybrid-35, W11 Hybrid-37, AVTOV-1007, AVTOV-1008 were observed for disease reaction. The control varieties were BARI Tomato-3, BARI Tomato-5, BARI Tomato-11, BARI Tomato-14 & BARI Tomato-15. None of the varieties were found to show complete resistance against leaf curl disease. However, W11 Hybrid-37, AVTOV-1010 showed very low level of incidence.
