“…These characteristics lead to reducing yields and difficulty in harvesting. Therefore, it needs a dwarf-type plant (less than 1.5 m) that exhibits an erect stem, a few branches, a long primary raceme (20-40 cm), and a harvesting age of fewer than 150 days (Lavanya et al 2018). The major producing countries, such as India, China, and Brazil have created dwarf varieties with high seed yields.…”

Abstract. Anggraeni TDA, Waluyo B, Sugiharto AN, Kuswanto. 2022. Genetic diversity analysis among 123 accessions of castor (Ricinus communisL.) using SSR marker and its association to agronomic traits. Biodiversitas 23: 1211-1221. Castor (Ricinus communis L.) breeding program targets to create dwarf-type plants suitable for mechanical harvesting. Characterization of plantsusing morphological and molecular markers can enhance the successful breeding program. This studyaimed to investigate the diversity of castor accessionsusing Simple Sequence Repeat (SSR) markers and find the SSR markers that are significantly associated with the agronomic traits. The castor germplasm collection consisting of 123 accessions from the islands throughout Indonesia, breeding lines, and introducedaccessions displayed a moderate genetic diversity. The germplasm collection showed high variation in plant height, node length average, number of nodes, 100 seed weight, and oil content. The association analysis using GLM (General Linear Model) and MLM (Mixed Linear Model) could detect six associations between SSR marker alleles and agronomic traits. Among the marker alleles, two marker alleles had an overlap association. RcSSR-12_175 had an association with plant height and flowering day, RcSSR-23_113 had an association with node length average and branch number, and RcSSR-4_125 had an association with seed weight/raceme. This finding could provide information on Indonesia’s castor accession status. The linked-trait SSR markers are useful in marker-assisted selection for breeding high yield dwarf type-castor.

“…The DEF has 0.69 entropy and three classes, 67% semi-dehiscent, 32% indehiscent and 1.0% of dehiscent genotypes. Fruit dehiscence results in losses of 2% to 45%, forcing premature harvests, leading to a decrease in oil content due to loss of yield (LAVANYA et al, 2018). Semidehiscent fruits promote a lower production cost, and there were 332 genotypes meeting this demand in the breeding, demonstrating that there is high potential in the selection to meet the demand of the breeding program.…”

Morphoagronomic characterization is a basic requirement to identify a phenotypic profile of a population. The quantification of variability allows efficient selection of superior and divergent genotypes. Thus, this study aimed to estimate the variability among 490 genotypes and seven strains, from an F2 population of Ricinus communis L., in 35 morphoagronomic traits and 12 agronomic traits. For qualitative descriptors, the entropy technique was used in the percentage frequencies of each category, computing its level using the coefficient of Rényi (1961). Quantitative descriptors were subjected to analysis of variance by the F test, and Tukey test was performed at 1% probability level. Of the morphoagronomic traits used, 13 were related to plants, nine were related to inflorescence, six were related to fruits and seven were linked to seeds, in addition to 12 agronomic traits. The material was arranged in the field with families (strains of five families) interspersed with their respective parents (controls). Stem color, shape and number of racemes collected, main color, type of secondary color and hundred-seed weight have high variability in the population, with formation of 68 groups as a function of genetic similarity. The possibility of selection as to the number of racemes harvested is clear, so it is possible to identify genotypes with higher number, aiming to enhance crop yield.
