The ecological manifestation of heterosis in breeding of cucumber

Abstract

The phenomenon of heterosis is widely used in agriculture. Scientists have conducted numerous studies on different cultures: tomatoes, beets, potatoes, wheat crossing lines grown in different environmental conditions, the hybridization of which receive a high heterosis effect for the mass production of hybrid seeds. The purpose of the research is to examine the environmental manifes-tation of heterosis in the cucumber by crossing maternal and paternal lines grown in different agro-ecological zones. Research objective: to identify the manifestation of ecological heterosis in hybrid combinations of cucumber when grown in the spring-summer and summer turnover of film greenhouses. The article presents indicators on the complex of economic and valuable features and properties in the spring-summer and summer turnover for 2017 and 2018. The manifestation of heterosis effect on early, total yield and yield of standard fruits was noted.
