abstract
Seven tomato hybrids viz; TMT 685, Abhimanyu, Shivaji, Vaishnavi, Suruchi, TMT-507 and PKM-1 were evaluated against whitefly, Bemisia tabaci during the year 2015–16 in a Randomized Complete Block Design with three replication having plot size of 4.5 x 3.6 m at JNKVV, DHRTC Farm, Garhakota (M.P.). The population of whitefly was recorded on tomato at weekly interval from appearance of the whiteflies. The results revealed that none of the hybrids was found completely free from the infestation. The infestation of whitefly started in the last week of August. The infestation increased gradually and reached to its peak in the last week of September. Thereafter, the population declined abruptly. The average minimum (5.69/plant) and maximum (9.85/plant) whitefly population during crop season was observed on Vaishnavi and PKM-1, respectively. According to mean of whitefly population the highest resistance was found in Vaishnavi followed by Suruchi, TMT-685, Shivaji, TMT-507, Abhimanyu and PKM-1. The highest marketable fruit yield (318.51 q/ha.) was found in Vaishnavi while, the minimum (97.53 q/ha) marketable fruit yield was recorded in PKM-1 hybrid. Among all the hybrids, Vaishnavi recorded only 8.20% disease incidence and found statistically significant as compared to other hybrids while the maximum disease incidence was observed in hybrid PKM - 1 (27.35%).
