The rin mutations were used to enhance the shelf-life of tomato fruits in commercial practice, with insignificant effects on the chemical content (decrease of total acidity and lycopene content in fruits) in F1 tomato hybrids with the rin/rin+ genetic constitutions. Male parental lines were of the rin+/rin+ genetic constitution. Storage of fruits (shelf-life) was the best in homozygous rin/rin parental lines Home-5 and Home-3 (from 118 to 125 days). In heterozygous rin/rin+ hybrids Nada F1, Sampion F1, Trezor F1, Sidra F1 and Rebus F1 shelf-life was from 18 to 30 days. This period is satisfactory for market needs and is much better than in commercial hybrids Balkan F1 and Marco F1 (5 and 8 days, respectively). There are now statistical differences between hybrids and lines in chemical components except in the lycopene content. The male parental lines had a low lycopene content (6.0 and 6.8 mg) in comparison with all hybrids (up to 13.2 mg).
