Abstract

The adaptive potential and ecological stability of new indeterminants of F1 tomato hybrids for cultivation in a prolonged culture in glass greenhouses of the "VENLO" type and the most selective valuable are determined.  Experimental researches were carried out in glass winter greenhouses of the "VENLO" type in the public joint stock company "Teplichny" (Kalinivka village, Brovarsky district, Kyiv region) in 2014-2017 and in the laboratory of the Institute of Agroecology of the National Academy of Agrarian Sciences.

 The plants of the studied F1 tomato hybrids have high stability (Sgi <25) on the basis of yield.  Hybrid F1 - Merlis, Torero and Maximato, and specially adaptive ability - Foronti, Maximato, Raisa (control) and Barthez had the high effect of general adaptive ability (Vi).  The hybrids F1 - Torero - 39,17 and Althez - 38,59 had high indexes of breeding value of the genotype.
