Mutations in the ethylene receptor gene (SlETR1), Sletr1-1 and Sletr1-2, are effective in reducing ethylene sensitivity and improving fruit shelf life. In this study the effect of Sletrl-1 and Sletr1-2 mutations was investigated in F1 hybrid lines. These two mutants and control were crossed with four commercial pure-line tomatoes. The Sletrl-1 mutation showed undesirable pleiotropic effects in the F1 hybrid lines. The Sletr1-2 mutation was effective in improving fruit shelf life of F1 hybrid lines for 4-5 days longer. It was also effective in improving fruit firmness without change in fruit size, ethylene production, respiration rate, and total soluble solids or a great reduction in fruit color, lycopene, and beta-carotene, although the titratable acidity was increased by Sletr1-2 mutation. These results indicate that the Sletr1-2 mutant allele has the potential to improve fruit shelf life via incorporation in tomato breeding programs.
