Low variability (coefficient of variation less than 10%) was characterized by: the duration of the interphase periods "seedlings-flowering", "flowering-ripening", the duration of the period "seedlings-ripening", "width and index of the fruit", "length of the main stem", "height laying the first inflorescence "," acidity "," vitamin C content ". The mean variables (10.1 to 20.0%) were: "average weight of marketable fruit", "number of chambers", "core diameter in cross section", "pulp content in juice" and "sugar content". High coefficients of variation (above 20%) had the characteristics "number of fruits per plant", "marketable productivity", "number of marketable fruits per plant", "number of inflorescences on the main stem" and "number of fruits on the second inflorescence". The sign "total productivity" had medium and high variability, "pericarp thickness" - low and medium, "lycopene content in fruits" - low and high variability. A database of phenotypic variability of twenty-four quantitative traits has been developed. The database is made electronically in Access and consists of four tables. High reliable correlations between total and marketable productivity (r = 0.95), total number of fruits and number of marketable fruits per plant (r = 0.91), average weight of marketable fruit and its width (r = 0.93) ), average weight of marketable fruit and chamber size (r = 0.77), average weight of marketable fruit and diameter of middle (r = 0.84), height of fruit and its index (r = 0.75), fruit width and chamber size (r = 0,0,86), width of a fruit and diameter of a core (r = 0,95), chamberness and diameter of a core (r = 0,92), duration of the periods of flowering-reaching and ladders-reaching (r = 0,88). Thirty-six tomato samples were evaluated for fifteen quality characteristics of the plant, leaf, flower and fruit.  Product Description popup.authors popup.nrat_date 2022-03-09 Close
