“…However, these statistical tools are insufficient for identifying genotype strengths and weaknesses and selecting those with desired mean performance and stability [48]. The MTSI is a sophisticated quantitative genetic technique for the exploitation of suitable genotypes across all crop species [47] and free from the multicollinearity problem [24].…”

Selection of Suitable Genotypes of Lentil (Lens culinaris Medik.) under Rainfed Conditions in South Italy Using Multi-Trait Stability Index (MTSI)

Lentil (Lens culinaris Medik.) is a popular legume crop in the Mediterranean region, widely grown for its nutritious seeds and improving soil fertility. Lentil yield is a critical and challenging trait for crop genetic improvement because it is influenced by various factors that have detrimental effects on seed yields and seed quality traits. This research was carried out in Italy between 2017 and 2019 to identify high-performing stable genotypes presenting multiple desirable traits and to assess the seed quality of 13 lentil accessions in the field. According to the results of the multi-trait stability index (MTSI), (1) only three accessions (Altamura, Easton, and Caltagirone) fared better in various environmental conditions, and (2) the selected accessions had strength toward seed yield (SY), above-ground biomass (AGB), and 1000-seed weight (THS). The genotype × environment interaction (GEI) effects were highly significant for all traits. During the third growing season, most lentil accessions were sensitive to frost. There was no correlation between lentil seed yield and protein concentration. The MTSI is a useful tool for breeders interested in selecting accessions based on their mean performance and stability, as well as desirable traits and minimum multicollinearity issues.

“…The index selection approach is an effective approach in multicharacter-based selection. The effectiveness of this approach has been reported by Authrapun et al (2021), Olivieri et al (2021), andFarid et al (2021). Basically, index selection uses index values from a combination of several selection criteria with specific weighting values (Wang and Chen 2016).…”

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.

Okra (Abelmoschus esculentus [L.] Moench) is an annual vegetable crop grown in tropical and subtropical regions of the world. Okra genotypes perform differently under different environmental conditions. Plant breeders have long struggled with the phenomena of genotype x environment interaction, which is a prevalent issue in plant breeding programmes. The main aim of genotype selection is to find okra genotypes with productive traits that might perform better under varied environmental conditions. The Multi-Trait Stability Index (MTSI) and Multi-Trait Genotype-Ideotype Distance Index (MGIDI) were employed for identifying high-performing stable genotypes exhibiting multiple traits. In the current investigation, 42 okra accessions grown in different seasons were assessed for 12 morphological traits. The results obtained by MTSI and MGIDI indexes revealed that, out of 42, only 4 genotypes performed better across the seasons and the four genotypes (UAHS-8, UAHS-10, UAHS-11 and UAHS-19) were selected in the indexes. View on strengths and weakness as described by the MGIDI and MTSI reveals the strength of the ideal genotypes in the present work is mainly focused on average fruit weight and fruit yield per plant. Due to their distinctiveness and ease of use in interpreting data with minimal multicollinearity difficulties, MTSI and MGIDI serve as novel tool for simultaneous genotype selection processes in plant breeding programmes across multi environments.
