IMPACT OF TOMATO SPOTTED WILT VIRUS (TSWV) ON YIELD CONTRIBUTING CHARACTERS OF EIGHT TOMATO VARIETIES UNDER FIELD CONDITION (Pages : 1 - 9)

An attempt was made to evaluate the performance of eight tomato varieties namely BARI-T1 (Manik), BARI-T2 (Ratan), BARI-T3, BARI-T7 (Apurba), BARI-T8 (Shila), BARI-T9 (Lalima), BINA-T1 and BINA-T2 against Tomato spotted wilt virus (TSWV) under field condition. The study was conducted at the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2005 to March 2006. Irrespective of tomato varieties and stages of infections, TSWV significantly (p=0.05) reduced the yield contributing characters of tomato plants as compared to healthy ones. Significantly higher percent of reduction to all the selected seven yield contributing parameters was observed when plants were infected with TSWV at early stage of infection as compared to mid and late stages. In consideration of yield contributing characters BARI-T9 seemed to perform better in comparison to other varieties when infected with TSWV.Download
