Germplasm material for spring false flax (<i>Camelina sativa </i>(L.) Crantz) breeding on the oil and protein contents in different ecological and geographical environments
We studied 315 samples of false flax ( Camelina sativa (L.) Crantz) from the collection of the All-Russian Institute of Plant Genetic Resources (VIR). The study was conducted over three years in four different ecological and geographical environments. On average, for three years at all places of the study, the oil content ranged from 33.0 to 37.4%, the protein content ranged from 24.7 to 29.7%. More oil accumulated in the conditions of the North-Western region - 37.1% and the Tambov region - 36.5%. The protein content in the Krasnodar and Astrakhan regions was almost identical and amounted to 28.6% and 28.4%. Correlation analysis showed an inverse relationship between the protein and oil contents in seeds. The correlation coefficients ranged from r = - 0.40 to r = - 0.76. Samples from the Northern Europe contained the highest oil percentage (37.5%), the highest protein content was observed in samples of the Siberian origin (27.8%). Analysis of the influence of temperature conditions and precipitation on the oil and protein contents in false flax seeds showed the relative independence of these traits from environmental conditions. The samples variability in terms of the regression coefficient of oil and protein contents from the sum of temperatures is 45.8 % and 46.6 %, respectively, from the sum of precipitation - 128.9% and 184.3%, which indicates a diverse response of samples to environmental conditions.
