“…The plants were irrigated periodically during the summer season. Before flowering, several racemes per plant were bagged using Kraft paper bags, as described by Fernández-Martínez and Velasco (2012). At maturity, the seeds from the bagged and open-pollinated racemes of each plant were collected.…”

“…It is cultivated on around 1.3 million ha, of which 0.9 million ha are in India (FA-OSTAT, 2021). Castor seeds are a very rich source of oil, which can reach close to 60% of the whole seed weight (Fernández-Martínez and Velasco, 2012). The oil is used for biofuel production and has several industrial applications, including the manufacturing of polymer materials, soaps, lubricants, coatings, cosmetics, and pharmacological products, among others (Patel et al, 2016).…”

“…The oil is used for biofuel production and has several industrial applications, including the manufacturing of polymer materials, soaps, lubricants, coatings, cosmetics, and pharmacological products, among others (Patel et al, 2016). For these applications, castor oil is mainly valued for its high ricinoleic acid (12-hydroxy-cis-9-octadecenoic acid) content, which typically accounts for 84 to 90% of its total fatty acid content (Fernández-Martínez and Velasco, 2012).…”

Castor is an industrial oilseed crop with great potential for biorefineries. However, little is known about the variability in the bioactive compounds in castor germplasm. This study evaluated seed weight, oil content, fatty acid profile, tocopherols, and phytosterols in 160 accessions of the USDA-ARS castor germplasm collection. The accessions were grown in Cordoba, Spain, under three different environmental conditions. Environmental and genotype-by-environment interaction effects were predominant for most traits, resulting in moderate to low broad-sense heritabilities, which ranged from 0.12 for total tocopherol content to 0.88 for hundred-seed weight. The genetic variability in the seed quality traits identified in the collection was lower than that reported previously for the germplasm of wild and semi-wild accessions from Spain, which is attributed to the lower genetic diversity in cultivated than in wild forms. The variation in seed quality traits in castor germplasm can be exploited to improve the concentration of bioactive compounds in castor cultivars.

“…It is also an effective technique for increasing the frequency of pistillate castor plants of the NES type [21]. Cultivars developed by mass selection are Kavkazskaya (in the former USSR), IAC-38 and BRS Energia (in Brazil), and Conver and Kansas (in the United States) [22,23]. Back cross method has been used to transfer monogenic traits such as dwarf plant stature, spineless capsules, stem color, bloom, non-shattering, plant height, and resistant to wilt.…”

“…Pedigree selection has been used to select high-yielding families and individual plant within the families. Subsequent progeny test for oil content and resistant to Fusarium wilt was done by Fernández-Martínez and Velasco [22] and developed wilt resistant cultivar Fioletovaya. Individual plant selection followed by progeny test was used to develop cultivar Guarany in Brazil [24].…”

Castor belongs to a monotypic genus Ricinus and subtribe Ricininae. It is one of the oldest plants, getting importance as an agricultural crop for subtropical and tropical countries in the world. Castor is a hardy plant, requires low input, tolerates marginal soils, is easy to establish in the field, is resistant to drought, and gives yield 350–900 kg oil per hectare. Castor oil shows great functional value in energy sector, industry, and pharmaceutical. In recent years, it received increasing demand in the international market for its more than 700 uses, ranging from medicine and cosmetics to biodiesel, plastic, and lubricants. The oil is significant for many industrial uses compared with other oils from plant sources because of its high and low temperature-tolerant properties. This chapter has been written to provide botanical descriptions, ecology, agro-technology, and versatile industrial uses.

Castor (Ricinus communis L.) is an oilseed species that can be grown as a semi-perennial in Mediterranean environments, including the coastal areas of Sicily. The present study investigated the optimization of cultivation techniques for castor, with the crop being maintained over a two-year period, through the evaluation of different agronomical inputs in order to increase seed yield. The effects of irrigation (I) and nitrogen fertilization (N) on the seed and oil yield and their components were assessed in castor cultivated in a typical semi-arid environment. Four levels of irrigation (I0, I30, I60, and I100: 0, 30, 60, and 100% of crop evapotranspiration—ETm restoration, respectively) as the main plot and three levels of nitrogen fertilization (N) (0, 60, and 120 kg N ha−1) as the sub-plot were considered. Irrigation mostly affected the number of racemes per plant, the number of capsules per raceme, and the seed weight. The oil content was, on average, 39.2% and 45.6% for the first and second year, respectively. The highest seed yield was obtained by I100N120 treatment (4154.0 kg ha−1); however, the combination of a high soil nitrogen level (N120) and medium water availability (I60) resulted in satisfactory seed and oil yields. The reduction in the irrigation water to an intermediate level could be also an environmentally friendly strategy not significantly affecting yields.
