“…The estimated broad-sense heritability values for yield component characters included height criteria such as pericarp thickness, fruit length, fruit diameter, fruit weight, number of locular cavities, and number of fruits. Several researchers reported similar results for pericarp thickness [1], fruit length [14], fruit diameter [1,10], fruit weight and number of locular cavities [9], and number of fruits [15]. The estimated heritability values for fruit yield characters per plant revealed high criteria.…”

Development of tomato in the lowlands is a solution to increase tomato production in Indonesia. Genotype selection using an appropriate criteria can help to obtain the tomato genotypes with have high production in the lowlands. This study was aimed to determine the appropriate selection criteria for tomatoes with high production in the lowlands. This study was organized in a randomized block design with three replications. The genotype used in this study was a collection of pure line from IPB's breeding laboratory. The results showed that several characters had a significant correlation with fruit weight per plant. Determination of selection criteria based on characters that have high heritability values with a significant correlation to fruit weight per plant. The characters of fruit length, weight per fruit and plant crown width have very significant correlation values with fruit weight per plant, so these three characters can be used as selection criteria.

“…According to the relevant literature, different scales of diversity are reported for the above-mentioned traits, as expected. For example, Özbay (2021) reported that flowering time varied between 12-30 days; Anisa et al (2022) reported that the number of flowers in a cluster varied between 6 and 8. Salim et al (2020) reported 59.09% of their observed genotypes as horizontal, 27.27% as semi-upright and 13.64% as semi-drooping.…”

This study was carried out in order to determine some morphological characteristics of 240 tomato genotypes at S2 level and to demonstrate the usability of these materials in breeding programs. Accordingly, the average fruit weight was between 553.11 gr and 74.83 gr. The mean pericarp thickness, carpel number, and soluble dry matter content of the genotypes were 7.38 mm, 3.6 pieces and 4.04% brix, respectively. Based on these measurements and observations, tomato genotypes were also investigated using the Cluster and Principal Component Analysis (PCA) methods. According to the PCA results, the first component explained 24.1% of the total variance, and the number of fruit carpels, average fruit weight, and fruit width were the most highly explained parameters. The second and third main components constituted 13.06% and 11.16% of the total. Based on the results of fruit characterization studies, genotypes 233, 447, 126, 22, 391, 118, 71, 100, 340, 102 were determined as superior. Overall, A high degree of morphological variation was detected among the characterized tomato genotypes.

“…The research has entered the F3 generation, hence the selection of these lines must be carried out systematically with a good accuracy approach. Single selection with productivity is considered very risky because the yield is polygenic with a complex genetic pattern (Anisa et al 2022). This indicates that multi-character selection needs to be carried out systematically on the F3 tomato population (Medico et al 2020).…”

Abstract. Farid M, Anshori MF, Ridwan I. 2022. Tomato F3 lines development and its selection index based on narrow-sense heritability and factor analysis. Biodiversitas 23: 5790-5797. The F3 is the early selection generation that has a good heritability and heredity pattern in a segregated population. The aims of this study are to identify the effectiveness of forming a selection index based on narrow-sense heritability and factor analysis and to select potential tomato F3 lines to be continued in the F4 generation. The research was arranged by an augmented design combined with a randomized complete block design as the environmental design. The research factors consisted of non-repeated genotypes, i.e. the lines with a limited number of seeds consisting of 75 lines and repeated genotypes as comparison varieties consisting of three varieties (Mawar, Tymoty, and Karina). The lines that were not repeated were divided into 5 blocks, while the check varieties were planted repeatedly in each block. The effective selection criteria in this study were the yield, fruit weight, number of branches, and total fruit number. The priority character besides yield in this study is fruit weight with high and normal narrow-sense heritability. The index selection results from this study showed that there were a good 32 tomato lines to be continued in the F4 generation. t was considered effective in the selection of tomato lines of the F3 generation.
