Abstract

VARIABILITY OF LICOPEN AND β-CAROTEN CONTENT IN TOMATO FRUITS The article presents data on the results of testing various tomato genotypes on the content of lycopene and β-carotene in fruits. The tomato genotypes studied showed a differentiated variability in the content of lycopene and β-carotene. According to the analysis of the distribution dendrograms of tomato varieties and lines based on biochemical indices, their separation into 2 large clusters was demonstrated. Samples from cluster 1 are characterized by higher indices of the biochemical characters studied. Varieties and lines were selected, with a high content of lycopene and β-carotene in fruits, which is an indicator of fruit quality. The varieties Rufina, Flame and the lines L 302, L 404, L 406, L 408, L 410 are characterized by higher indices of the biochemical characters studied and can be successfully used as initial material in improving the quality of tomato fruits. Keywords: tomatoes, varieties, biochemical parameters, variabilitate, licopen, β-caroten.
