Abstract

C. sativa is a valuable oilseed; it has a wide nutritional and technical use. The purpose of this study is a comprehensive study of C. sativa collection accessions in various ecological and geographical conditions to determine the environmental stability parameters. C. sativa All-Russian Institute of Plant Genetic Resources (VIR) collection accessions served as a material source for the study. The study was conducted in four different ecological and geographical regions of the Russian Federation. In the factor structure of the environmental parameters variability two factors are identified covering 94.8% of the variability. The first factor is associated with the precipitation sum (PS) and the temperatures sum (TS) for the vegetation period (68.7%), the second factor is associated with the average daily temperature (TM) for the same period (26.1%). Analysis of the system of correlations between the parameters of stability and plasticity and the value of regression coefficients for meteorological indicators showed that for all the studied features, indicator b closely correlates with regression coefficients for the temperatures sum (TS) and average daily temperature (TM) for the vegetation period. Indicator Sd—with coefficients for the precipitation sum (PS) and average daily precipitation (PM). The result of the study made it possible to identify collection accessions of C. sativa with a high stable adaptability to the contrasting climatic conditions of the studied regions.

Highlights

Accepted: 10 February 2021Currently, Russian Federation is facing the task of increasing the production of vegetable oil of food and technical usage, since 40% of all used oils in the country are imported.The problem can be solved through the introduction of low-spread oilseed cruciferous crops, such as camelina [1]
The first factor is associated with the sum of precipitation (PS) and temperature (TS) for the vegetation period (68.7%), the second is associated with the average daily temperature (TM) for the same period (26.1%)
As a result of the C. sativa study on the main parameters of stability and ecological plasticity in four contrasting eco-geographical conditions, accessions that are characterized by high resistance to various climatic cultivation conditions were identified

Summary

Introduction

The problem can be solved through the introduction of low-spread oilseed cruciferous crops, such as camelina [1]. Camelina sativa (L.) Crantz is an oilseed crop belonging to the family Brassicaceae. Interest in the study and cultivation of camelina is shown in Europe, Canada, the United States and other countries of the world [4,5,6,7,8,9,10]. In European countries, the yield of camelina amounts to: 1.9 t/ha in Germany, 2.8 t/ha in France [7]. In Canada, the yield of camelina can reach 3 t/ha [11], and in the USA 2.3 t/ha [12]
