“…Higher heritability for most of the traits were also advocated" by Aralikatti et al [15] and Maunika et al [16] Saravanan et al [17], Singh et al [18] However, days to 50 % flowering shows low estimates of heritability.…”

The present investigation was carried out in randomized block design with three replications during Rabi season of 2020-21 to judge the extent of genetic variability and scope of selection among thirty-two genotypes including two checks of tomato Narendra Tomato-4 (NDT-4) & Narendra Tomato -7(NDT-7) for fourteen characters. In present study the analysis variance showed that all the treatments were significantly different for all the characters. Which, indicates wide range of genetic variability among the available genotypes. On the basis of mean performance, five genotypes namely NDT-28, NDT-29, NDT-30, NDT-32 and NDT-P were promising ones. High genotypic (GCV) and phenotypic (PCV) coefficient of variations were recorded for plant height, number of primary branches, polar diameter of fruit, equatorial diameter of fruit, locules per fruit, average fruit weight, marketable fruit yield per plant and total fruit yield per plant. Moderate genotypic coefficients of variation and phenotypic coefficients of variation were estimated for ascorbic acid content, number of fruits per plant and pericarp thickness. In contrast, low environment coefficient of variation was found for all the characters. High heritability (broad sense) coupled with high genetic advance in per cent of mean was observed for plant height, equatorial diameter of fruit, locules per fruit, pericarp thickness, average fruit weight, number of fruits per plant, marketable fruit yield per plant and total fruit yield per plant. Thus, ample variability is there and selection will be effective among the available germplasm of tomato.

“…Such traits are less under the influence of environment. High heritability coupled with high genetic advance have also been reported for most of the yield and yield attributing traits" by Sajjan et al [20], Bhandari et al [21], Singh et al [18], Kumar et al [22] and Kumar and Yadav [23].…”

“…Genetic diversity is crucial in producing cayenne pepper varieties adaptive to low lightintensity stress. Genetic diversity was the main asset in plant breeding (Singh et al 2015); the higher genetic diversity, the greater the opportunity for plant improvement according to the desired idiotype. This variation provides ample scope for the plant breeder to select superior genotypes for crop improvement (Sujatha and Pushpavalli 2017).…”

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.
