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.

Effect of supplemental Ca2+on NaCl-stressed castor plants (Ricinus communisL.)Greenhouse experiments were conducted to assess the effects of supplemental Ca2+in salinised soil on germination and plant growth response of castor plant (Ricinus communisL. Var. Avani-31, Euphorbiaceae). NaCl amounting to 390 g was thoroughly mixed with soil of seven lots, of 100 kg each, to give electrical conductivity of 4.1 dS m-1. Further, Ca(NO3)2x 4H20 to the quantity of 97.5, 195, 292.5, 390, 487.5, and 585 g was separately mixed with soil of six lots to give 1:0.25, 1:0.50, 1:0.75, 1:1, 1:1.25, and 1:1.50 Na+/Ca2+ratios, respectively. The soil of the seventh lot contained only NaCl and its Na+/Ca2+ratio was 1:0. Soil without addition of NaCl and Ca (NO3)2x 4H20 served as control, with a 0:0 Na+/Ca2+ratio. Salinity significantly retarded seed germination and plant growth, but the deleterious effects of NaCl on seed germination were ameliorated and plant growth was restored with Ca2+supply at the critical level (1:0.25 Na+/Ca2+ratio) to salinised soil. Supply of Ca2+above the critical level further retarded seed germination and plant growth due to the increased soil salinity. Salt stress reduced N, P, K+and Ca2+content in plant tissues, but these nutrients were restored by addition of Ca2+at the critical level to saline soil. In contrast, Na+content in plant tissues significantly increased in response to salinity, but significantly decreased with increasing Ca2+supply to saline soil. The results are discussed in terms of the beneficial effects of Ca2+supply on the plant growth ofRicinus communisgrown under saline conditions.

Castor Plant

Evidence of castor plant R. communis, L. is recovered from the Early Holocene archaeological site of Kabbashi Haitah in the Central Sudan and dated to c. 7700 - 7200 bp. This evidence represents the earliest botanical evidence recovered –so far- from the Central Sudan and elsewhere in Eastern Tropical Africa and the World. No evidence is found in the material culture remains which might indicate the likelihood of its being imported. Most of the ancient and traditional utilizations of castor plant are strikingly similar despite their being practised at different times in different and far apart regions in the World. This modest contribution stands to show that the wide spread and utilizations of castor plant strongly accentuate its significant and indispensable role since ancient times. It also reflects that inedible plants, as seen in the case of castor plant, were (and still are) not less important than food plant, hence stresses the need for attending to their study in a fashion equal to that of studying foodplants since prehistoric and early historic times.

And Storage

Two new anthocyanins (1, 2) were isolated from the stem bark of the castor plant, Ricinus communis L. by a combination of chromatographic techniques. The structures of the compounds were elucidated, mainly by nuclear magnetic resonance spectroscopy and high-resolution electrospray mass spectrometry, to be cyanidin 3- O-β-xylopyranoside-5- O-β-glucopyranoside (1) (21%), and cyanidin 3- O-β-xylopyranoside-5- O-(6′”- O-malonyl-β-glucopyranoside) (2) (79%). In addition, cyanidin 3- O-β-xylopyranoside-5- O-(6′”- O-methylmalonate-β-glucopyranoside) (3), formed by methyl esterification of the malonyl unit of 2 during isolation and storage, was identified.
