“…PC1, with an eigenvalue of 6.41, contributed 53.42%, the PC2, with an eigenvalue of 1.64, contributed 13.66% (Figure 3), and the PC3, with an eigenvalue of 1.21, contributed 10.05% to the total diversity among the 20 test genotypes. The large cumulative variance of the 3 main components indicates that the traits between them greatly influenced the phenotype, so they can be used for selection among test genotypes (Rosmaina et al 2022).…”

Abstract. Siahaan GF, Chozin MA, Syukur M, Ritonga AW. 2023. Estimation of genetic parameters and variability of various cayenne peppers under net shading. Biodiversitas 24: 5912-5919. The intercropping systems are important concerning the decreasing agricultural land and the increasing population. Chili could be planted as intercrops, but not all chili genotypes were adapted to low light-intensity stress. This study aims to determine the genetic diversity of cayenne pepper under 50% plastic net shade conditions based on morphological and agronomic traits. The study was conducted at the Cikabayan Experimental Field, Institut Pertanian Bogor, Dramaga, Bogor, from January to July 2021. The genetic material consisted of ten genotypes of cayenne pepper from Capsicum annuum L. and ten from Capsicum frustescens L.. Each genotype of chili was planted with three replications, so there were 60 experimental units. Each experimental unit consisted of six plants planted in an area of 1.5 m2. The shade used was a plastic net shade with a 50% shading level. The estimation of genetic parameters showed that leaf area, number of leaves, fruit weight, number of fruits, and yield per plant had a high genotypic coefficient of variation (GCV) and broad-sense heritability (Hbs). Cluster analysis resulted in two main clusters based on twelve chili growth and agronomic characters. All chili genotypes included in Cluster 1 were C. annuum chilies. On the other hand, all the chili genotypes in Cluster 2 were C. frutescens chilies except for the G19 genotype. Cayenne pepper in Cluster 2 had a higher number of leaves, plant height, stem diameter, leaf area, fruit diameter, pedicle length, fruit weight, number of fruits, and yield per plant than cayenne pepper in Cluster 1. The result of this study indicates that C. frutescens cayenne pepper has more potential to be planted under shading conditions and used in intercropping than C. annuum.

“…Respon tanaman terhadap cekaman kekeringan dapat dilihat pada tahapan pertumbuhan tanaman yang disebabkan oleh intensitas cekaman, lama kekeringan, frekuensi kekeringan dan jenis varietas tanaman (Hanum et al, 2017). Penggunaan varietas toleran yang tahan terhadap cekaman kekeringan merupakan salah satu alternatif cara yang efektif dan efisien (Rosmaina, 2019;Lita, 2018). Dewasa ini sudah banyak jenis tanaman cabai rawit dibudidayakan dimasyarakat dan banyak varietas yang sudah dilepas oleh pemerintah.…”

The aim of this research is to obtain information on the resistance of several local cayenne pepper varieties from Southeast Sulawesi to drought stress. The study was conducted at Field Laboratory II, Faculty of Agriculture, Halu Oleo University, Kendari, which took place from January to June 2022. The research consisted of two experiments, namely the seed phase and the plant phase. The first experiment used a Factorial Randomized Block Design (RAK). The first factor was drought stress, consisting of 3 levels of PEG concentration (0, 7.5, and 15%). The second factor was the type of cayenne pepper, including 2 national varieties: Dewata and Bara, as well as 4 local cultivars from Konsel, Konawe, Muna, and Kendari. The second experiment also used a Factorial Randomized Block Design (RAK). The first factor was watering with field capacity (KL): 100, 50, and 25%. The second factor was the same as in the first experiment, which was the type of cayenne pepper. The first experimental variables were germination ability, germination weight, and drought stress index in the seed phase. The second experimental variables were plant height, number of leaves, root length, fruit weight, and stress tolerance index in the plant phase. Observational data were analyzed using variance analysis, followed by the BNJ test with a 95% confidence level. The results of the research showed that there was an interaction between the drought stress treatment and the type of cayenne pepper plant, which had a significant effect on plant height, root length, and fruit weight per plant. However, for germination ability, germination weight, and the number of leaves, each factor had an independent effect. With the 15% PEG treatment in the germination phase, the resistant cayenne pepper varieties were the cultivars from Muna and Konsel, while the 25% field capacity treatment for the plant phase of resistant cayenne pepper were Dewata and Bara varieties, cultivars from Muna and Konsel.

“…Also, in developing countries, water shortages result in massive losses of grain annually, and global climate change will probably cause additional losses as well [8,9]. Drought tolerance is the capacity of plants to survive and produce a desired crop in the presence of water scarcity [10].…”

Drought stress constricts crop production around the world. Employing high-yielding cultivars with drought tolerance might be the ideal professional approach to coping with its detrimental outcomes. As a result, the current study was performed to investigate the sensitivity and tolerance of nine wheat genotypes to drought stress. In a randomized block design experiment, nine wheat genotypes were subjected to four water treatments: 100%, 85%, 70%, and 55% of the available water (AW). Four water regimes in two growing seasons were counted as eight environmental zones. The leaf’s water relations and photosynthetic pigment were estimated, as well as growth and yield parameters. Univariate and multivariate statistical approaches, including the new method of multi-trait genotype–ideotype distance (MGIDI), were used for evaluation. The analysis of variance revealed that genotype, environment, and their interactions had a highly significant effect on all traits. The same trend was shown by the additive main effects and multiplicative interaction (AMMI) analysis of variance for grain yield across the environments. The AMMI biplot study indicated that the G8 genotype is the most stable in terms of water stress. The G7 genotype can withstand droughts up to 55% of the available water, while the G8 and G3 genotypes can withstand droughts up to 70% of the available water. Based on all examined traits, this index was used to identify the stable genotypes G7, G8, and G3, which can therefore be suggested for cultivation during drought conditions. Furthermore, we found a positive correlation between the MGIDI, ANOVA, and tolerance index results, indicating that the same desirable genotypes of G7 and G8 were identified by these procedures as being highly tolerant and stable across a range of soil moisture conditions. Based on MGIDI analysis, we can recommend that the G7 genotype exhibits higher grain yield and yield-related traits with the best drought-tolerant indices.
