Tomato (Solanum lycopersicum L.) is a main horticultural crop for income and nutrition to urban and peri-urban communities. Invasion by Tuta absoluta has caused high damage and loss threatening livelihood of farmers in Tanzania. Host resistance mechanism of tomato landraces own unique physiological and biochemical traits that can fight against pest attack. This study screened twenty-one landrace varieties for their vigorous and resistance against T. absoluta in three major tomatoes growing zones of Tanzania. Findings showed that landraces had high growth rates resulting in many leaves per plant averaging 29.04 ± 1.12 compared to improved cultivar (Tengeru 97) that possessed 18.75 ± 0.62 leaves/plant. Landrace varieties yielded high tomato fruits averaging 18.82 ± 1.93 t/ha and 91.66% of marketable yield in contrast to improved variety th.. View More»
