The present study aimed to estimate the nature and magnitude of variability in the castor germplasm concerning yield and its component traits and physico-biochemical characters. Seed yield per plant and oil content ranged from 80.90 g (ICS-165) to 248.30 g (RG-3216), and 34.7% (ICS-172) to 58.7% (JI-277), respectively. The iodine value of oil ranged from 76.36 (JI-370) to 89.84 (P2-135) with an average value of 83.02. The mean saponification value of oil was 182.24. The genotypic and phenotypic coefficients of variation were high for acid value, capsules on the main raceme, seed yield per plant, and total length of the main raceme. A positive association of porosity, average unit volume, and total length of the main raceme with seed yield per plant showed that these characters might be directly attributed to seed yield improvement. By Manhattan distances, the 30 genotypes were grouped into 3 clusters. Their genetic diversity was elucidated using SSR and SRAP markers. SRAP marker produced higher mean number of total bands (5.71), polymorphic bands (4.57), percentage polymorphism (83.10%), PIC (1.72), RP (5.90), mean RP (1.02), MR (5.71), EMR (4.57) and MI (1.44) values when compared to SSR (2.89, 2.11, 79.63%, 0.61, 1.90, 0.72, 2.89, 2.11 and 0.49, respectively) marker.

In this study, based on castor bean genome, three <em>RcSUCs</em> (<em>RcSUC2, RcSUC3 and RcSUC4</em>) were identified and characterized. The expressional profiles of <em>RcSUCs</em> in different tissues such as leaf, stem, root, phloem and seed tissues exhibited a distinct divergence of gene expression, suggesting that the functions of <em>RcSUC2, RcSUC3</em> and <em>RcSUC4</em> are differentiated into long or short-distance transportation among tissues. Additionally, under abiotic stresses including hot temperature, low temperature, drought and salt stresses, the sugar allocation among leaf, stem and roots was tested. The expressional changes of <em>RcSUCs</em> in leaf, stem and root tissues were associated with sugar transportation and allocation. Taken together, the differential expression of <em>RcSUCs</em> among tissues responsing to abiotic stress suggested functional differences in sucrose transport and redistribution in different tissues.
