Abstract
Sweet potato is one of the most important root crop worldwide. This study aimed to compare agro-morphological characteristics of four sweet potato varieties (Martina, Janja, Lučka, Purple Speclet) from organic farming with additional information about their genetic background. A total of 26 agro-morphological traits were evaluated during vegetation. Pre-grown seedlings were planted in organic fields during the 2021 growing season using the soil ridge cultivation method. The study showed significant differences between varieties in quantitative (except for the extent and intensity of anthocyanin colouration on abaxial veins) and qualitative traits (except for the number and length of primary shoots and internode diameter). The varieties Lučka and Martina proved to be significantly higher yielding compared to the other two varieties. The genetic background of the varieties was evaluated on 8 SSR loci using allele polymorphisms with a total number of 34 different alleles and an average polymorphic information content of 0.60. The favourable informativeness of the selected markers was confirmed by the global genetic diversity of 0.68. The assignment of each genotype to two genetic groups agrees well with the varietal distribution in the phylogenetic tree and the results of the analysis of the genetic structure (Martina/Janja and Lučka/Purple Speclet). The present study contributes to a better knowledge of the sweet potato varieties considered and their agro-morphological and genetic diversity.

Abstract
In this paper, we used a shape matching algorithm to recognize Farsi digits. For each sampled point on the contour of a shape, we obtain a descriptor showing the distribution of the other points of the contour, with respect to this point. Based on these descriptors, we find the corresponding points of the two contours and take the sum of their distances as a dissimilarity measure between two shapes. Then we define a geometric transformation that maps the sampled points of the one shape to the corresponding points of the other shape. The bending energy of this transform is taken as the second dissimilarity measure between two shapes. We optimized the parameters of the matching algorithm for the recognition of Farsi digits and used the method of minimum distance from the class prototypes for the recognition. In a test on a set of 1288 digits, we obtained a recognition rate of 89.9%. This result was obtained without any post processing

Abstract
This research aims to explore the role of description in Parviz Natel Khanlari's poem The Eagle using the framework of Descriptology. By critiquing previous perspectives on description and offering a fresh view on the nature of description in literature, this study seeks to answer key questions, such as the roles of the descriptor and descriptee, the distinction between the descriptor and the narrator, and the difference between the descriptee and the narrative audience. Additionally, it examines the impact of description on the style and success of a literary work. Employing a combination of analytical philosophy and Descriptology, alongside statistical data analysis, the poem The Eagle is meticulously analyzed. The findings reveal that description plays a crucial role in creating mental imagery, conveying concepts, and establishing a connection with the reader. The study also refines and expands the typology of description, investigates the relationship between narrative and descriptive elements, and evaluates the quantitative and qualitative aspects of descriptions within the text. The results demonstrate that Descriptology, with further development, can become a powerful tool for comprehensive and in-depth analysis of literary works. This research enhances the understanding of The Eagle and its complexities, offering valuable insights for literary critics, theorists, researchers, writers, and those involved in AI-based linguistic modeling.
Introduction
In literary research, description is often regarded as a tool for establishing context for events or portraying characters. Prominent writers and writing instructors emphasize its importance. However, the boundaries between description and related concepts continue to remain ambiguous. Descriptology, as a field of study, seeks to define and categorize various types of description within literary texts, providing a structured framework for analyzing texts from a descriptive perspective.
This study draws on analytical philosophy, which is prominent in academic departments across regions such as Britain, North America, Australia, and Scandinavia, to explore the nature of description. The poem The Eagle by Khanlari, considered one of the ten best contemporary poems by Shafiei Kadkani, is chosen for its rich descriptive elements and literary success.
Research Questions
- What is description?
- What are the types of descriptors and descriptees?
- How is Khanlari’s The Eagle critiqued and evaluated from a Descriptology perspective, particularly through the lens of descriptor and descriptee?
Literature Review
Descriptology, initially developed in relation to the story of Rostam and Sohrab, has since been applied in various studies to critique and analyze literary texts. Previous research has explored description in historical novels, contemporary stories, and other texts, often relying on the theoretical frameworks provided by Descriptology.
Discussion
The study delves into the nature of description, distinguishing between its linguistic and literary definitions. In analytical philosophy, description is seen as a symbolic representation of reality, while in literature, it often serves to create vivid imagery and convey deeper meanings. The research identifies various types of descriptors and descriptees, categorizing them based on their roles within the narrative.
In The Eagle, the third-person narrator often serves as the descriptor, providing detailed descriptions of the eagle, its surroundings, and other characters. The poem’s rich descriptive language enhances its emotional and visual impact, creating a multi-layered narrative that engages the reader on multiple levels.
Conclusion
The study concludes that description is an integral element of language and literature, far from being a mere static or ornamental feature. Descriptology offers a new horizon for literary analysis, offering precise and insightful methods for critiquing and interpreting texts. The findings highlight the importance of hidden descriptions, which often carry deeper meanings and contribute to the text’s overall impact.

Abstract
Wild pepper (Capsicum frutescens L.) could be a source of variation to improve cultivated pepper due to its unique traits with adapting challenges caused by adversity. Interspecific hybridization has been used as an effective way of pepper introgression breeding, which transfers genes of interest from wild relatives to cultivated crops. Here, eight fertile hybrids F1 were produced from pepper (Capsicum annuum L.) and the wild relative (C. frutescens), as female and male, respectively, by interspecific hybridization. Interspecific hybrids were identified using conventional morphological descriptors and SSR molecular markers. The results showed that significant differences in agronomic traits existed among cultivated pepper, wild relatives, and interspecific hybrid F1. Interspecific hybrid F1 presented intermediate values, although they were closer to the wild species in most of the agronomic traits. Analysis of SSR markers clearly showed that interspecific hybrid F1 had bands from the paternal and maternal accessions, which indicated that F1 hybrid was heterozygous. Our results provide hybrid for breeder to transfer genes of interest from wild relative, C. frutescens, to cultivated pepper, which is an important step for introgression breeding.
