Aim: to distinguish hybrids of pumpkin by carotene content and by pectin content with a complex of valuable economic characteristics. Methods: selection, statistical. A line Nasoloda (C. maxima) and line BAK-1 (C. moschata) was allocated for the NCGRRU. New hybrids Faraon F1 (C. maxima) and Romashka F1 (C. moschata) have been submitted for state testing. Ukrpatent has sent an application for a useful model "Method of selection of high-carotene forms of pumpkin". "Methodical recommendations for heterosis selection of pumpkin for carotene and pectin" have been developed. Nasoloda. Commodity yield - 26.6 t / ha (+4.6 t / ha or 20.9% to the analogue), fruit weight 3.7 kg (+0.9 kg), the content of soluble dry matter is 12.4%. Economic effect 13.8 thousand UAH / ha. BAK-1. The analogue prevails in marketable yield by 6.0 t / ha (25%), dry matter content by 0.6%. Сommodity yield - 30.0 t / ha, average fruit weight - 4.9 kg, dry matter content - 10.6%. Economic effect 15.0 thousand UAH / ha. Faraon F1. Commodity yield - 36.9 t / ha (+4.9 t / ha or 15.3% to the analogue). Faraon F1 exceeded in dry matter content (14.24%, + 2.20% to the analogue), ascorbic acid (17.67 mg%, +2.56 mg / 100g), beta-carotene (5.16, + 0.65 mg%), pectin (3.14%, + 2.13%). Economic effect 10.2 thousand UAH / ha. Romashka F1. Commodity yield is 29.7 t / ha (+6.0 t / ha; + 25.3% to the analogue), the dry soluble matter content is 11.0% (in the analogue - 10.0). Hybrid exceeded the analogue in dry matter content by 3.36%, beta-carotene by 4.01 mg%, pectin by 2.20%. Economic effect 13.6 thousand UAH / ha. The method of selection of high-carotene forms includes evaluation of samples for carotene content by side effects (intensity of color of pistils and flesh). Approved in the agricultural enterprises. Application: melon growing.
