Abstract

Abstract. Sayekti TWDA, Syukur M, Hidayat SH, Maharijaya A. 2021. Diversity and genetic parameter of chili pepper (Capsicum annuum) based on yield component in three locations. Biodiversitas 22: 823-829. With the increase in the use of chili, it is necessary to develop these commodities through plant breeding activities. Phenotypes are not only determined by genetics, but also by environmental factors and the GxE interactions, so all the factors need to be considered. The aims of this study were to evaluate the variability of ten elite breeding lines and three commercial varieties of chili pepper (Capsicum annuum L.) across three different environments. This experiment was conducted in three environments namely Bogor, Kolaka, and Palembang, from January until July 2019. Thirteen genotypes consisting of ten elite lines and three commercial chili pepper were used. This experiment was arranged in a randomized complete block design (RCBD) with three replications for each environment. To determine the effect of environment, Combined Analysis of Variance was carried out for all environments using PBSTAT-GE. The environment used in this experiment was lowland that varies between each other. The genotype with the fastest harvesting age relative in three environments was F7-145293-19-8-3-113-1. The highest number of fruits per plant was observed in genotype F9-160291-9-4-3-2-1-1-1 with 261 fruits per plant. The highest yield was observed in genotype F7-145174-9-7-1-5-3. From the clustering analysis, this population was grouped into five clusters. The heritability values for the 12 observed traits ranged between 22.68-69.97%, classified into high and moderate criteria.

Organic foliar fertilizer to improve yield of cayenne pepper (Capsicum frutescens L.) grown off-season

“…This variety produced relatively the same number of fruits when was grown in three different environments [17]. Other studies showed that the number of fruits variable in cayenne pepper has a high heritability value, around 97%, which means that the genetic influence is very large [17]. However, the phenotypic coefficient of variation and genotypic coefficient of variation for the number of fruits per plant variable is relatively the same, around 19.5%.…”

“…The same result was shown by an earlier study on one of the OP varieties in Indonesia, Bara. This variety produced relatively the same number of fruits when was grown in three different environments [17]. Other studies showed that the number of fruits variable in cayenne pepper has a high heritability value, around 97%, which means that the genetic influence is very large [17].…”

Genetic Characteristics of F2 Populations Obtained Through Double and Three-Way Crosses in Cayenne Peppers

“…Growth and production traits with high heritability values have also resulted in past studies for plant height, fruit diameter, number of fruit per plant, fruit weight, and fruit weight per plant (Qasim et al, 2013); plant height, stem diameter, flowering age, harvest age, fruit length, and fruit diameter (Syukur and Rosidah, 2014); and stem diameter and fruit length in cayenne pepper populations (Rosmaina et al, 2016). Traits, such as, fruit length, diameter, and weight with the highest genetic variation and heritability should be considered reliable selection criteria for increasing chili yields (Sayekti et al, 2021). High heritability values indicate that the influence of genetic factors was more significant and prevailing than environmental factors.…”

Growth and morpho-physiological assessments of Indonesian red chili cultivars on early vegetative stage under water stress conditions: A comparison of waterlogging and drought

“…It is also linked to the adaptation of cellular osmotic potential (Pilon et al, 2019). Meanwhile, plants increased stomatal regulation to maintain internal water availability, which led to a decrease in stomatal index and leaf size to limit water loss (Lestari et al, 2023).…”

“…In this study, the tolerant and susceptible cultivars were evaluated by examining the phenotypic characters as an initial screening process. Lestari et al (2023) reported that genetic factors had a greater influence on morpho-physiological traits under different environmental conditions. Genetic approaches are also needed to support early indication within screening research, such as the use of molecular markers as a tool to estimate the genetic diversity of plant species in the genomic era (Rini and Nuraisyah, 2021).…”
