Oilseed crops are a valuable source of vegetable oils, which can be converted to biofuels and other biobased products through various chemical transformations. New oilseed crops are gaining the attention of both scientific and industrial audiences in view of their unique fatty acid compositions, new rotation options, and the ability to grow an oilseed crop on land where commodity oilseed production is not currently economically viable, creating opportunities for novel industrial applications and the replacement of petrochemical feedstocks with sustainable alternatives. The integration of new oilseed crops into existing agricultural systems requires research in areas ranging from genetic improvement and agronomic management to life cycle and value chain analyses. New oilseed crops include camelina, crambe, pennycress, carinata, Indian mustard, castor bean, safflower, cuphea, Andean lupine, hemp, and others. This Special Issue will focus on “New Oilseed Crops for Biofuel and Biobased Applications”. We welcome novel research and reviews covering a range of topics in oilseed crops, including crop genetics and improvement, production management, biodiversity, crop physiology, phytoremediation, integration of industrial oilseed crops into food cropping systems, growing oilseed crops on marginal land, modeling, lifecycle assessment, economics and marketing, and policy.

Title: Crambe abyssinica: a high-value oilseed with potential to improve

Abstract: Crambe seeds contain high levels of erucic acid (C22:1), a fatty acid of importance for industrial applications. Inclusion of crambe into crop rotations will be beneficial due to its short life cycle, low fertility requirements, resistance to pest and diseases, and relative drought tolerance. Currently, high erucic acid rapeseed (HEAR) is considered the prominent source of industrial erucic acid. However, the risk of contaminating food-quality rapeseed (canola) by cross-pollination and the negative impact on climate is problematic in HEAR cultivation. Crambe has great potential to at least partially replace HEAR as a source of erucic acid, if the knowledge-gaps in agronomic management and crop improvement can be addressed.

Abstract: The emerging oilseed crop camelina (Camelina sativa L. Crantz) is gaining interest worldwide due to its wide environmental adaptability in combination with satisfactory seed production and a large portfolio of end-uses, either for food, feed or non-food applications. Despite being not yet widely cultivated, camelina has been identified as a much more resilient species than the “sister crop” oilseed rape (Brassica napus L. var. oleifera), in relation to input requirements, pest and disease resistance, and resistance to abiotic stress (e.g., temperature, drought, etc.). One of the main advantages of camelina compared to oilseed rape is its extreme drought tolerance, also at the germination phase. The availability of both winter and spring camelina biotypes, characterized by different seed sizes, raises the question about possible differences in their response to drought stress at the emergence stage. To address this, under controlled conditions, a germination test was set up comparing 12 different camelina genotypes (6 winter + 6 spring) with differing seed sizes (ranging from 1.83 to 0.88 g/1000-seeds) under increasing levels of osmotic stress (0, -0.4, -0.8, -1.2, -1.6 Mpa) using PEG.

Abstract: Given the growing interest in camelina crop, due to its great environmental adaptability, low input requirements and unique seed oil profile, seven cultivars and two sowing times (spring and autumn) were compared for quantitative and qualitative yield in a Mediterranean environment. For this, a field plot experiment was set up over two years in Central Italy, by adopting a split-plot design with sowing times as main plots and cultivar as subplots, replicated four times in both years. Sowing date and cultivar affected the number of days and GDD accumulated from emergence to 50% flowering: across the year, the number of days decreased as sowing was delayed, passing from 124 days, as mean value over the cultivar, for autumn sowing, to 62 days for spring one. Regarding GDD, very little differences were observed between the two sowing dates (500 vs 478 GDD accumulated from emergence to 50% flowering, for autumn and spring sowing, respectively), while more consistent variations have been detected among cultivars. CAM11 and CAM26 were the earlier ones starting flowering after having accumulated 426.5 and 413.2 GDD in spring sowing respectively, and, 474.3 and 515.7 GDD in autumn sowing. Sowing date significantly affected yield and yield components, except for the number of seeds per siliqua. Autumn sowing increased seed yield per hectare (+18%) and per plant (+65.1%), TSW (+5.2%) as well as seed oil content (+5.5%). The genetic characteristics also played a significant role in defining the agronomic performance of camelina. In particular, CAM32 showed the best seed and oil yield when sown in autumn, whereas CAM11 and CAM2 were the best performing genotypes with a spring sowing. Across years and cultivars, mean seed yield increased from 1.6 to 1.9 t ha-1 from spring to autumn sowing but reached as high as 3.4 t ha-1 with CAM32. Genotype and year did not influence oil content that fluctuated largely between 34 and 44%. A correlation analysis was also performed to understand the relationships between yield components and between them and environmental conditions. These correlations pointed out that both TSW and number of siliques per plant were the key components in defining camelina yield. Camelina compensated to some extent for lower stands by an increase in number of siliques per plant and seeds per siliqua, and higher rainfall amount, especially during spring, seemed to enhance camelina production and oil content. Climatic conditions affected the response of seed oil quality to sowing date, while genotypic characteristics seemed to have a minor effect on the oil profile. However, autumn sowing increased the content of alpha linolenic, eicosenoic, erucic and eicosadienoic acids and the ratio of polyunsaturated to saturated fatty acids. In conclusion, our results can represent the starting point to select, in relation to sowing date, the most suitable cultivars for the Mediterranean environment, in terms of earliness, adaptability, quantitative and qualitative performances.

Abstract: The increasing demand for biomass for bioenergy and biomaterial production generates land-use conflicts with food crops. To overcome competition for land use , the use of heavy metal-contaminated sites for the production of industrial crops is an option. Moreover, industrial crops may also contribute to the remediation of soils contaminated with heavy metals through phytoremediation processes. The aim of this work was to study the effects of Ni and Cd on the growth, yield and biomass quality of two different oilseeds: Brassica carinata A. Braun and Thlaspi arvense L. The soils were artificially contaminated and the concentrations chosen were based on the limits established by the Decree Law 276/2009 (Portuguese regulation that establishes the guidelines for the use of sewage sludge in agricultural soils) - Ni: 110 mg/kg; Cd: 4 mg/kg; and twice those limits - Ni: 220 mg/kg; Cd: 8 mg/kg. Soils without contamination served as control. In terms of biomass and seed production, B. carinata was affected by Ni but not by Cd. Contrarily, T. arvense biomass and seed production was significantly reduced due to the contamination of the soils by both metals, with yield losses much higher due to Cd. Both crops accumulated Ni and Cd in the aboveground biomass, in the siliques and in the roots, in growing concentrations with increased soil contamination. But, due to the yields obtained, B. carinata had better prospects to simultaneously produce biomass and oil-bearing seeds, along with its ability to remediate contaminated land.
