Abstract Camelina [Camelina sativa (L.) Crantz], an oilseed crop, belongs to Brassicaceae family. Two unique features of camelina in comparison with the main oil crops are adaptation to different environments and also its unique oil composition. Development of doubled haploid plants is one of the essential methods for the crop improvement. This research was conducted to evaluate the genetic variation of 81 Camelina doubled haploid (DH) lines obtained from fifteen crosses by ISSR markers. The total number of amplified bands was 243, of which 239 bands (98.3%) showed polymorphism. The percentage of polymorphic bands (PPB) varied between 93.75 and 100. The size of the bands ranged from 50 to 1,700 base pairs. The informative ISSRs were identified by estimating marker features: polymorphism information content (PIC), effective multiplex ratio (EMR), marker index (MI) and resolving power (RP). Three markers had higher RP values (9.88, 8.5 and 7.46) and were the most informative markers to identify the DH lines. Cluster analysis based on Complete algorithm divided the lines into five groups, indicating relatively clear configuration from the geographic distribution patterns of the parents of the doubled haploid lines. Principal coordinate analysis (PCoA) classified the 81 camelina DH lines into six groups. The lines grouping by these two methods was similar to each other. The ISSR markers detected high polymorphism to reveal genetic variation of camelina DH lines. The findings of this research, along with biochemical traits, can improve classical and molecular breeding programs of camelina.

Abstract The technology for in vitro anther culturing was optimized in hexaploid triticale using combination of external factors that allowed to obtain more than 100 doubled haploid lines. Investigation of genetic variation among anther culture derived doubled haploids of triticale showed the occurrence of heterozygous plants.

Abstract The aim of this study was to determine the influence of weather conditions over the course of 4 years (2016–2019) on the fatty acid profile of Camelina sativa. It was assumed that varieties and functional forms of plants (spring and winter genotypes) were characterized by a different fatty acid composition and that weather conditions affected the profile of fatty acids in camelina seeds. Statistical analyses were performed based on the results of chemical tests. Differences were found in the mean concentrations of C18:3n3, C18:3n6, C20:2 and C22:1 acids in all genotypes based on the Kruskal test. Two winter genotypes (Maczuga and 15/2/3) and the spring genotype UP2017/02 had the significantly highest content of C18:3n6. Genotypes CSS-CAM31, CSS-CAM30, BRSCHW 28347, CSS-CAM36 and Kirgzkij showed the highest content of C18:3n3. The lowest C18:3n3 content was found in winter genotypes: K9/1, 15/2/3, Przybrodzka (winter form) and C5. It was found that weather conditions deviating from the long-term average, both in terms of temperature and precipitation, did not affect the quantitative profile of fatty acids. Over the 4 years, no differences were observed in the fatty acid profile between the spring and winter forms. Observations made in this study allow to state that spring and winter forms of Camelina sativa retain a constant fatty acid composition regardless of changing weather conditions.

AbstractThe present study aimed to determine the effect of the use of Camelina sativa oil as a dietary ingredient for laying hens on their growth performance, fatty acid profile of yolk lipids, and egg quality parameters. In the experiment, 72 Hy-Line laying hens of age 26 weeks were randomly assigned to three groups with four treatments. Control group (I) was fed the diet containing 4% rapeseed oil (RO group). Experimental groups were fed diets containing 4% camelina oil (CSO group) and 10% camelina cake (group CSC). Feed consumption was measured for each group. The number of laid eggs and their weight were recorded every day. Eggs for the assessment of quality parameters were collected in the last 3 days of the experiment. Egg quality, chemical composition of yolk, and fatty acid profile were determined. Organoleptic evaluation was performed on boiled eggs. The inclusion of C. sativa oil or camelina cake in the laying hen diet did not affect egg weight, albumen quality, or taste and flavor. The experimental groups also showed a tendency toward an increase in the proportion of yolk in the egg (%). Addition of 4% camelina oil or 10% camelina cake to the diet of laying hens reduced monounsaturated fatty acid level in yolk lipids and significantly increased n-3 PUFA content, in particular ALA, EPA, and DHA, compared to the control group.

Freezing stress is an important abiotic stress that limiting the yield and the spatial distribution of many important crops. This study was undertaken to screen 136 doubled haploid (DH) lines of camelina (Camelina sativa L.) along with four canola (Brassica napus) cultivars (Hyola 401, Lord, Roska and Cascade) as experimental control under freezing stress conditions (-14?C for 6 h) to identify lines with high or low level of tolerance to freezing stress for further studies. First, a protocol was developed for large scale screening of camelina germplasm under freezing stress conditions. For this purpose, an experiment with different freezing temperatures (-5, -10, -15 and -20?C) was conducted to find an appropriate temperature that discriminated best between genotypes (i.e. the LT50 temperature). The LT50 values for camelina lines were varied between -10.2 and -17.1?C with an average of -13.94?C for all of the camelina lines. Therefore, we selected the -14?C exposure for 6 h as an appropriate temperature to screening of camelina lines. The principal components of measured parameters (LT50, survival percentage, relative conductivity and scoring) was using principal component analysis that determine freezing-tolerant and freezing-sensitive lines. Among 136 doubled haploid lines, some lines (58, 62 and 101) had higher level of freezing tolerance and some of them (8, 16, 32, 91 and 107) were freezing sensitive. The selected lines in a preliminary freezing screening are useful for further evaluations.
