“…Castor oil currently has more than 700 uses, and its market is limitless due to its diverse applications, ranging from industrial to pharmacological uses [23]. The world demand for castor oil and its derivative, castor biodiesel, is continuously growing at the rate of about 3 to 5% per annum, especially as they are essential for preventing the freezing of fuels and lubricants used in aircraft and space rockets at extremely low temperatures [24]. With the development of biodiesel, castor oil's primary market is expanding into the energy sector [25].…”

Hybridization is an important evolutionary force, and heterosis describes the phenomenon where hybrids exhibit superior traits compared to their parents. This study aimed to evaluate the one-hundred-seed weight and fatty acid content in F1 generations, investigating the effects of different parental crosses using a 9 × 3 incomplete diallel design (NCII). One of the challenges faced in this study was the complexity of accurately determining the influence of both genetic and environmental factors on trait inheritance. A total of 36 F1 crosses were analyzed for general combining ability (GCA), specific combining ability (SCA), and heritability. The results showed that the level of each index in F1 is closely related to its parents. Significant differences in GCA and SCA were observed among parental traits in most crosses. The ratio of GCA to SCA ranged from 0 to 3, indicating the pivotal role of SCA over GCA in castor breeding efforts. High narrow-sense heritability was recorded in palmitic acid (30.98%), oleic acid (28.68%), and arachidonic acid (21.34%), suggesting that these traits are predominantly under the control of additive gene action, and hence these characters can be improved by selection. Additionally, heterosis exhibited diverse patterns across traits. Based on the evaluated combining ability, heritability, and heterosis, the inbred lines CSR181 and 20111149 were recommended for castor crossbreeding due to their potential to yield progeny with optimal oil-related traits. This research contributes valuable knowledge to the field of castor breeding, providing a foundation for developing superior castor cultivars.

“…Castor oil (Ricinus communis L., Euphorbiaceae), an important inedible oilseed, is primarily grown in the globe's drylands and semi-arid regions, which are mainly native to the tropics [1][2][3][4]. The castor plant Ricinus communis L. produces castor oil, which is a key chemical feedstock for a wide range of products ranging from polymers to cosmetics and has numerous applications.…”

Ricinus communis L. is a flowering plant species from the Euphorbiaceae family; it contains about 300 genera and 7500 species and belongs to the monotypic genus Ricinus. This study aims to investigate morphological, genetic diversity, and chemical analysis of castor bean (Ricinus communis) growing in Riyadh Saudi Arabia. Using a modified Cetyl Trimethyl Ammonium Bromide (CTAB), total plant genomic DNA was extracted from young leaves of each genotype. Four random HAP primers (HAP1, HAP2, HAP3, and HAP4) were used for RAPD PCR analysis proximate analysis was done for chemical analysis. Primers produced 32 DNA fragments 4 were polymorphic bands and 28 were not polymorphic bands polymorphism between two plants in bands was revealed in phonomertic characters that were recorded in this study. Four random HAP primers (HAP1, HAP2, HAP3, and HAP4) were used for RAPD analysis of the two castor bean (Ricinus communis) populations to detect polymorphism. The study showed that the result of proximate analysis protein in seeds was 16% in sample A and 15% in sample B while the total ash was 2.7 in sample A and 2.3 in sample B and fat was 47 and 47.8 respectively in samples A and B, the study recommended that it needs further study of the two castor bean (Ricinus communis) using suitable samples from two populations and it must make DNA sequencing to clear variation between the two types.

“…Evaluating the genetic variability using markers is necessary for using genetic resources in plant breeding programs (Saadaoui et al, 2017). Determining the genetic variability of a breeding collection via SSR (Simple Sequence Repeat) molecular markers helps in identifying genotypes with desirable characteristics for developing new cultivars (Kiran et al, 2017).…”

Genetic variability in genotypes of safflower via SSR molecular marker

The safflower is an oleaginous plant belonging to the Asteraceae family. It is used as a raw material for various purposes. These plants are popular for the quality and quantity of oil produced and, and thus, studying their genetic variability using markers is necessary for determining genetic resources to conduct breeding programs. Therefore, we evaluated the genetic variability of safflower genotypes using Simple Sequence Repeat (SSR) molecular markers. The study was conducted at the State University of Mato Grosso “Carlos Alberto Reyes Maldonado”, in the Campus of Cáceres-MT. In total, 121 safflower genotypes from the Germplasm collection were evaluated using 21 SSR markers. The programs GenAlEx 6.5, GENES, and Structure were used to analyze the data. We identified 158 alleles at 21 loci among the genotypes. The expected heterozygosity (He) was high (0.551 - 0.804), but the observed heterozygosity (Ho) was low (0.000 - 0.502), and the indices of the endogamy coefficient (F) were positive in all loci and all populations, with an overall average of 0.958. The genetic differentiation (FST) values among populations were low, with an average of 0.010, which suggested a low population structure. The modified Tocher clustering and the UPGMA hierarchical clustering yielded 19 and 15 distinct groups, respectively. The genetic structure showed two populations, with few intermixes in the genome. The evaluated safflower genotypes showed genetic variability, and these genetically different variants might be used in breeding programs to obtain cultivars adapted to Brazil.
