Abstract Castor (Ricinus communis L.) has been transformed from a wasteland colonizer to an important industrial oilseed crop. Its seed oil is one of the most sought-after vegetable oils because of its rich properties and variety of end-users. Castor is an ancient crop but its production now has been limited mainly to India, China and Brazil, for many reasons. Castor oil is a hot market commodity product. It has been recently recognized as an efficient feedstock for biodiesel production. Increasing demand world over for biofuel resources and many recently identified industrial uses of castor oil have escalated castor oil demand. Global demand for castor oil is rising constantly at 3-5% per annum. In the last decade, many countries have started making serious exploratory efforts at growing castor as there is a tremendous scope to establish castor as a supplementary crop production option to farmers and to provide significant returns on investment given high global demand for castor oil. In view of the increasing worldwide interest in castor oil, this review evaluates the global scenario of castor cultivation, exports and imports of castor oil, new interests in castor oil and genetic improvement in productivity. In addition, the current research challenges and priorities have been discussed in the review.

The paper characterized and transesterified castor seed oil. The resulting product was tested as feedstock for biodiesel production. It was carried out at the Department of Mechanical Engineering, the Federal University of Technology, Akure, Ondo State, Nigeria, over a period of eight months. The oil was extracted in a soxhlet extractor with n-hexane as the solvent. The oil obtained was filtered and then characterized. Transesterification was carried out using a laboratory scale biodiesel processor. The fuel and physico-chemical properties of the oil and its biodiesel were determined following ASTM, EN and AOCS methods. The results revealed that all the properties of the biodiesel are within the ASTM limits for biodiesel except the kinematic viscosity. The oil contains 89% ricinoleic acid and has high solubility in methanol due to the hydroxyl group and requires minimum amount of catalyst to give maximum biodiesel yield. The heating value obtained for the oil and its biodiesel were 32 MJ/kg and 38 MJ/kg. The castor seed oil investigated has oil content of 34%, and the properties characterized are all within the limits for biodiesel.  Castor oil has excellent solubility in methanol and hence theoretically an ideal feedstock for biodiesel production.

AbstractCastor is an industrially important oilseed crop. Vascular wilt caused by the soil borne fungus Fusarium oxysporum f. sp. ricini is a serious disease of castor. Use of resistant cultivars is the only viable option for management of wilt disease problem in castor production. Excellent sources of resistance to wilt have been found in castor germplasm. In this study, a set of four castor inbred lines (48–1, CI-1, AP42 and AP48) was characterized for inheritance of resistance to wilt by studying segregating populations generated by crossing these inbred lines with eight different susceptible genotypes. An artificial screening method (sick pot) with a new scoring system (days to wilt) was used for evaluation of plant progenies for reaction to the pathogen infection. The reaction of F1s indicated that the nature of resistance in 48–1, CI-1 and AP48 is recessive whereas it was dominant in AP42. Inheritance results from eight F2 populations showed that resistance to wilt is conferred by a single locus in one population and at least two loci, which interact in complementary way, in other seven populations. Different modes of inheritance were also observed when the same resistant source was crossed with different susceptible parents, indicating the possible role of genetic backgrounds in determining resistance. Overall, the results suggested that Mendelian resistance to wilt is predominant in the castor genotypes, which can be exploited for breeding cultivars. Particularly, AP42 with dominant nature of resistance will be of great interest to hybrid breeding.
