Abstract
Tomato genotypes with resistance to begomoviruses derived from different wild species were evaluated in Guatemala. Selection of individual plants for several generations resulted in breeding lines with high levels of resistance. Resistance derived from L. hirsutum was dominant, while resistance from the other sources was more recessive in nature. Crosses among resistant lines resulted in higher levels of resistance for F1 populations than crosses between resistant and susceptible lines. Resistant lines were crossed to susceptible lines with other traits of interest, namely resistance to other pathogens and desirable fruit characters. Improved breeding lines with begomovirus resistance have been selected from these hybrids. These breeding lines are currently being used in the production of begomovirus-resistant hybrids with acceptable market quality and yields.
