“…The position of this chili is dropping. This can be due to the type of chili that can also affect the position of the fruit (Lahbib et al 2021). 5; 6; 7; 8; 9; 10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20; 23; 25; 26; 28; 29; 30; 33; 35; 36; 37; 38; 39 ; 12; 13; 14; 26 ; 28; 39; 5; 6; 9; 16; 19; 20; 23; 25; 33; 35; 36; 37; 40; 15; 11; 27; 32; 7; 8; 18; 29; 30; 38; 17; 31; 34; 10; 12; 13; 14; 26 ; 39; 5; 6; 9; 16; 19; 23; 25; 33; 35; 36; 37; 40; 15; 11; 27; 32; 7; 8; 18; 29; 30; 22; 28; 38; 39; 19; 23; 33; 35; 36; 37; 40; 27; 29; 20; 31; 26; 32 Semi dropping 2; 1; 24;5;6;25;11;30;34;22;21 Dropping 17;3;10;12;13;14;9;16 ;15;7;8;18;4…”

Abstract. Sahid ZD, Syukur M, Maharijaya A, Nurcholis W. 2022. Quantitative and qualitative diversity of chili (Capsicum spp.) genotypes. Biodiversitas 23: 895-901. The diversity of chili species in tropical climate areas, especially Indonesia, is very diverse. Information on the performance of chili both quantitatively and qualitatively is needed to form the basis for future research. This study aimed to obtain qualitative and quantitative character information on several chili genotypes. The results showed that there were differences in chili genotypes based on qualitative and quantitative characters. The genotype that excelled quantitatively in terms of fruit weight was CK 12. In addition, this genotype had a square fruit shape that was absent in other genotypes. The highest number of fruit in this study was indicated by pure lines F8 145291-14-9-3-12-1-1 and Bara. Cluster analysis based on quantitative characters (HCA Analysis) grouped all genotypes into three major groups where the CK 12 genotype separated into one group of its own. The information in this study is very useful for research and development of chili plants.

Pepper (Capsicum spp.) is one of the most important crops worldwide. The fruits of Capsicum species are known to contain high amounts of vitamins and carotenoids, and they have health-promoting properties. In this study, a total of 513 pepper accessions belonging to two Capsicum species, C. annuum and C. frutescens, were investigated for their morphological characteristics and contents of phytochemicals including carotenoids, β-carotene, vitamin C, capsaicinoids, and total soluble solids. The results revealed wide variations in morphological traits and phytochemical contents between the accessions and across species. In addition, the association of fruit color and orientation with phytochemical contents was evaluated; the results indicated that germplasm with yellow-colored and pendant-oriented fruits could be important due to their high vitamin C levels. Multivariate analysis of the agro-morphological and phytochemical parameters revealed that Capsicum germplasm were clearly distinguished according to species. Furthermore, cluster analysis showed that germplasms belonged to three groups, and six genotypes were determined as being good genetic resources with high health-promoting phytochemical contents. Especially, vitamin C content was positively correlated with fruit diameter, weight, and wall thickness. Our findings revealed morphological and phytochemical characteristics potentially useful for breeding programs.

The relationship between fruit position, ripening stage, and variety has not been well studied in pepper plants. To understand the interaction of these factors, a diversity of phytochemical traits as well as antioxidant activity were investigated with agronomic traits in eleven hot pepper varieties collected from the upper and lower parts of the plant and harvested at three maturity stages (green, orange, and red). Capsaicin content (CAP) showed a relatively high genetic effect; on the contrary, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity were more affected by the ripening stage and fruit position. The CAP values ranged from 0.29 (‘FKbM’) to 0.77 (‘Bka’) mg CAP equivalents g−1 DW. The ripening stage was the predominant factor for TPC, TFC, DPPH, and FRAP. There was no significant interaction between A × FP, A × RS, and FP × RS for all agro-morphological fruit traits. Variety, fruit position, and ripening stage effects are more significant than all interactions calculated. Lower fruit positions in all samples showed a maximum fruit size, whereas phytochemical traits and yield per plant were relevant in the upper parts, and Phytochemical traits and yield per plant were significantly correlated. From PCA and cluster analysis, all varieties showed the highest biochemical and antioxidant levels with moderate fruit size, except the ‘Bel’ variety that showed the smallest fruit traits with high yields, and the ‘FKbM’ and ‘FKbK’ varieties that showed the highest fruit size but low yields. This study supplies information to identify interesting cultivars with considerable levels of bioactive and phytochemical metabolites, which is useful for breeding programs of novel varieties.
