Abstract

There have been generalized the study results of the parameters of ecological adaptability of winter durum wheat and there have been identified the most adaptive varieties of different ecology under unstable climatic conditions of the Rostov region. There was conducted the analysis of 34 varieties of domestic and foreign breeding, which have been recommended for cultivation in different climatic zones. During the current study there have been identified the groups of winter durum wheat varieties that were different in their ecological adaptability parameters. The first group included 11 highly responsive varieties recommended for cultivation on an intensive background, namely ‘Alyy parus’, ‘Kontinent’, ‘Laguna’, ‘Kassiopeya’, ‘Akveduk’ (Ukraine), ‘Prikumskaya 142’, ‘Eyrena’, ‘Kiprida’, ‘Terra’, ‘Oniks’, ‘Kurant’ (Russia). To obtain the largest average productivity there have been recommended to cultivate the following 11 varieties on the average agricultural background, namely ‘Aksinit’, ‘Amazonka’, ‘Kermen’, ‘Uniya’, ‘Diona’, ‘Yakhont’, ‘Yubilyarka’, ‘Belgorodskaya yantarnaya’ (Russia), ‘Zolotoye runo’, ‘Gardemarin’, ‘Andromeda’ (Ukraine), since these varieties were good adapted to various environmental conditions. The varieties ‘Agat donskoy’,‘Zolotko’,‘Krupinka’, ‘Laska’, ‘Lazurit’, ‘Krucha’, ‘Stepnoy yantar’ (Russia), ‘Burshtin’, ‘Dnepryana’, ‘Perlina odesskaya’ and ‘Shulyndinka’ (Ukraine) -to cultivate on a reduced agrofone, where they will give a fairly high yield from 8.45 to 9.67 t / ha.

Highlights

Durum wheat Triticum durum Desf. is considered to be the second largest crop in the world after soft wheat
At the last stage of the breeding process, special influence is paid to productivity improvement, and to the study of ecological adaptability of varieties, i.e. a comprehensive assessment of the initial material according to adaptability and stability parameters, which makes it possible to identify promising genotypes by various characteristics [8]
Adaptability is considered as the ability of a genotype to maintain its characteristic phenotypic expression of a trait under certain environmental conditions, and stability is the ability of regulatory mechanisms to maintain a specific phenotype in different environmental conditions

Summary

Introduction

Durum wheat Triticum durum Desf. is considered to be the second largest crop in the world after soft wheat. At the last stage of the breeding process, special influence is paid to productivity improvement, and to the study of ecological adaptability of varieties, i.e. a comprehensive assessment of the initial material according to adaptability and stability parameters, which makes it possible to identify promising genotypes by various characteristics [8]. It is they that are of the greatest value in agricultural production, since they are able to produce large and high-quality yields in various soil and climatic zones, weather and agricultural conditions [9, 10, 11]. In difficult soil and climatic conditions, there should be grown varieties with a larger adaptive potential [13]
