Abstract
 
Castor plant with the scientific name Ricinus communis L. is one of the oil plants of the Euphorbiaceae family cultivated in many parts of Iran. Castor plant is one of the important medicinal plants used in the cosmetic, health and pharmaceutical industries. Its medicinal properties are associated with the presence of phytochemical compounds such as alkaloids, flavonoids and tannins. The purpose of this study is to study the morphological characteristics of 15 different genotypes of castor bean plants under the climatic conditions of Isfahan province. This research was conducted in the form of a randomized complete block design and three replications in the research farm of Islamic Azad University, Isfahan (Khorasgan) Branch in the year 1400-1401, located in eastern Isfahan, Khatunabad. Average comparisons between the investigated genotypes showed that the Isfahan genotype had the lowest number of clusters and the highest plant height and stem length. Jiroft and Malair genotypes had the highest number of clusters with 5 and 4 clusters, respectively. Jiroft, Fars and Mashhad genotypes had a capsule size of 2.6 cm. Mashhad, Shahrekord and Zahedan genotypes had the highest number of leaves with 34, 33 and 29 respectively, and Mashhad and Shahrekord genotypes had the highest and lowest weight per thousand seeds with 524.61 grams and 132.72 grams, respectively. Mashhad and Jiroft genotypes had 23 and 21 sub-branches, respectively. In addition, the Shahrekord genotype was the lowest with a seed width of 6.89 mm. Jiroft and Shahrekord genotypes had the highest and lowest stem cross-sectional areas with 3 cm2 and 1.3 cm2, respectively. In general, there is considerable genetic diversity between castor plant genotypes in terms of morphological characteristics. High yields of 1,000 seed weight, capsule size and cross-section are available to the food and pharmaceutical industries by growing Mashhad, Fars and Jiroft genotypes in Isfahan.
