    • Abstract:
      The assembly of cayenne pepper (Capsicum frutescens L.) cannot be separated from the direction of qualitative character development. This is based on the role of qualitative characters in determining nutritional content and market segments. Therefore, the analysis of qualitative characters in the F 4 multiple cross cayenne pepper population needs to be done in determining the direction of line development in the next generation. The purpose of this study was to identify the inheritance pattern of qualitative traits and genotype grouping from a population of F4 multiple cross lines. The research was conducted at the Experimental Field of Hasanuddin University, Makassar, Indonesia. The study was designed with the concept of observation on 90 F4 multiple cross chili lines and three parental cultivars (Dewata F1, Bara and Ungara). Observations focused on 10 qualitative characters. The analysis showed that there are two types of diversity in this population, namely centralized diversity and distributed diversity. Centralized diversity consists of leaf color, book color, leaf shape, canopy density, stem color, fruit shape, and fruit tip shape. In contrast, characters that have a diverse distribution are crown color, young and old chili fruit color. The distribution results show three main groups, namely the Dewata -Bara group (27 genotypes), the Ungara group (16 genotypes) and the rest are groups outside of these two groups. Based on the whole study, the results of this evaluation are recommended as a consideration for the selection of F5 lines in supporting the direction of releasing chili cultivars from multiple cross.
