The best genotypes, which are characterized by high plant productivity and stability, are the varieties Snihovyk (1.49), Tovstiy Dzhek (1.18), Morozenko (0.79), Gina (0.92). The above-mentioned varieties and samples do not contain an increased lycopene content in fruits, but they can be used in breeding work for high productivity. Among the samples with an increased lycopene content, the high selection value in terms of productivity was possessed by samples MO 112 (1.03), the average - by samples No. 3 (0.61), Manapal (0.60), T 3627 (0.59), line No. 289 (0.57) and sample No. 11 (0.55). The genotypes that had high commercial productivity of plants and stability were established: the Snihovyk variety (1.17), the samples Tovstiy Jek (0.90), Gina (0.79) and the Morozenko variety (0.79). Due to the low lycopene content in the fruits, they can be used only as one of the components of crossing for high commercial productivity. Among the samples with an increased lycopene content, the average selection value in terms of marketability was for samples MO 112 (0.60), No. 3 (0.49) and sample No. 11 (0.47). A new selection material was created - line LK 4 with a lycopene content in fruits - 8.09 mg/100g, a duration of the "seedling-maturing" period - 109 days. marketable yield under rainfed conditions - 44.5 t/ha, a dry soluble matter content of 5.52%, vitamin C - 31.62 mg/100g, total acidity - 0.31%, high relative stability (14.42) and high selection value (5.63) in terms of lycopene content in fruits.
