(Sendt), Longum D.C., Pomifera Fingerh иFascicullatum Sturt,including the varieties and the hybrids, from own selection. <...> It was shown, that the results of the β-carotene content testing by the GOST 8756.22 and by the high performance liquid chromatography method are correlated (r = 0.99), that is relatively comparable. <...> The intensity of fruits color during the phase of technical ripeness exactly correlates with provitamin A content, however, the fruits color and provitamin A content during the phase of biological ripeness doesn’t interrelated. <...> To obtain the new initial pepper material with a complex of practical valuable determinants, including a high content of provitamin A, ascorbic acid and anthocyanins in fruits, the authors recommend to use the tame mutant forms of pepper of natural and artificial origin with A,Im and bc genes. <...> Keywords: vegetable pepper, quality selection, -carotene, anthocyanin, cultivated mutants. -Carotene, vitamins C and E are very important components of human diet. <...> This fact determines a creation of agricultural crops varieties with increased contents of β-carotenoids in fruit. <...> In particular, there are almost no data on possible interactions of a mutant gene bc encoding this trait with A and Im genes controlling anthocyanin synthesis <...>
