Abstract
Relevance. In the consumer market, there is a popular pumpkin in portion sizes weighing 1.0 to 2.5 kg. To meet the needs of the population and producers in pumpkin fruits, F1 varieties and hybrids with high economically valuable traits, portion size and manufacturability in production and processing are needed.
Material and methods. The purpose of the research is to analyze, isolate and select the best breeding samples for creating parental lines of butternut pumpkin and large-fruited portion size.
The experiment was carried out at the selection plot of the FSBSI "Federal Scientific Rice Centre" from 2015 to 2019. The objects of research were cultivars, hybrid populations, cultivars and samples obtained from different sources.
Results. Lines with a number of economically valuable traits are highlighted, including portion size, productivity, biochemical parameters and commercial attractiveness of fruits. According to the length of the growing season, all inbred lines were divided into 3 groups: early maturing, mid-maturing, late maturing. In terms of productivity, the following lines stand out: KrChkh, BatS, La. The following lines were distinguished by the content of dry soluble substances (SRV, mg%): KrChkh, LaChkh, BatS, LaN. In muscat lines, the number of marketable fruits per plant varied from 3.3-5.7 pcs / plant. According to keeping quality, the test samples were divided into several groups: the least keeping quality among the studied samples was the line 15-5 (105 days); in fruits of lines 24-3, 16-5, 15-1, the safety of fruits increased to 116-126 days. The 28-2 line (162 days) was the highest keeping quality. The rest of the lines were attributed to medium bikes (133-148 days). All selected lines were characterized by a female type of flowering, multi-fruiting, short-leaved and good keeping quality of fruits. The KrChx line has a pronounced leaf aerenchyme. The organoleptic analysis showed that all the lines identified have a high score of 4.5-5. All commercially valuable traits in the lines are fixed with an inward.
