Short Communication: Morpho-agronomic performances of bird pepper (Capsicum annuum) lines under varying agro-ecological locations in Indonesia. Biodiversitas 23: 4838-4843. Bird pepper price fluctuations are caused by an imbalance between production and market demand. One effective way to overcome this is to increase the productivity of bird pepper. Genetics and the growing environment of bird pepper greatly affect the productivity produced. Therefore, this study aimed to determine the character of yield and yield components of four genotypes of bird pepper at three lowland locations. Planting was carried out at three locations representing Indonesia's bird pepper growing environment. The planting procedure in all sites was carried out according to the same guidelines. A randomized complete block design (RCBD) was used with three replications. Twenty (20) plants per genotype were planted in each replicate, with 10 plants taken as samples. Shiara IPB had the highest productivity in all environments compared to the other line. The main characteristics that distinguish this variety had a purplish color on the fruit petals when young, and the fruit color was greenish-yellow. Hierarchical cluster analysis results showed that Shiara IPB in almost all observation variables based on legend color was superior. The highest productivity was found in Palembang, followed by Bogor and Kolaka.

Morpho-physiological seed diversity and viability of Indonesian cowpea (Vigna unguiculata)

“…Post hoc analysis was carried out, including 5% HSD test, Hierarchical Cluster Analysis, Genotype cluster analysis, and Pearson correlation which was carried out while the ANOVA showed significant results. HCA visualization using the "heatmaply_package" and R Color Brewer (coul: PuRd) using R Studio (Syukur et al 2022). Pearson correlation analysis visualization also uses the same program as the ggplot_package (Syukur et al 2023).…”

Evaluation of qualitative and quantitative traits of ten lowland chili genotypes

“…Plant growth is caused by the activity of xylem formation, phloem, and cell enlargement, these activities push the cambium out to form new cells so that the plant grows taller (Setiawan et al, 2019;Rahayu & Sri, 2018). Plants with high plant height are expected to produce high productivity (Syukur et al, 2022b). The diameter of the stem determines the strength to support the plant crown.…”

“…Variations in growth and yield components have been reported in many studies (Sharma et al, 2010;Thul et al, 2009). Plant breeding activities are expected to be able to produce superior genetic material (Syukur et al, 2022b). The genetic material used and the environment where chili is grown are the main factors that influence chili productivity (Jeeatid et al, 2018;Kim et al, 2019).…”
