“…The selection based on multiple traits can produce balanced outcomes with the selection. Two studies that evaluated cowpea genotypes in Cerrado (the Brazilian tropical savanna), based on multiple traits, identified the superior lines for most of the combinations between yield and the key traits during the cowpea breeding through the GYT Biplot (Oliveira et al, 2019;Cruz et al, 2020;Araújo et al, 2021). The use of the GYT index in selecting multiple traits became a promising strategy as compared to the traditional indexes.…”

“…Considering the socio-economic importance of cowpea plants in certain regions of the world (Kebede;Bekeko, 2020), and mainly in Northeastern Brazil, that approach allows combining the yield with other key traits of the breeding lines (Yan;Frégeau, 2018;Yan et al, 2019). The selection of multi-traits has been carried out in the cowpea breeding and, most commonly, through the selection indexes (Torres et al, 2016;Omirou et al, 2019) with few studies using the GYT Biplot approach (Oliveira et al, 2019;Cruz et al, 2020;Araújo et al, 2021). According to the latter authors, the methodology allows the selection of superior cowpea lines by focusing on the combinations between yield and other traits of interest with easily interpreted results.…”

Selection of superior cowpea lines for multi-traits and adaptabilities to the Piauí semi-arid using genotype by yield*trait biplot analysis

Cowpea is a great socioeconomically important leguminous plant worldwide. The crop is an excellent source of proteins and minerals, mainly for the poorest populations. It is cultivated in some states of Brazil. The Piauí semi-arid is the most yielding zone in the state. Thus, the selection of superior cowpea genotypes for multi-traits and adaptabilities to this growing area is very important for the small-scale and medium-scale farmers in Piauí. The objective of this study was to select the superior cowpea lines for their multi-traits and adaptabilities to the Piauí semi-arid zone based on the genotype by the yield*trait (GYT) Biplot approach. Seventeen elite lines and three cultivars were evaluated in a randomized complete block design with four replications under the rainfed growing condition at three different locations away from the Piauí semi-arid zone. The following traits were evaluated: the number of days to flowering, pod length, the number of grains per pod, weight of one hundred grains, grain index, grain yield, Fe and Zn contents, and also the cooking quality. The analysis of variance (ANOVA), the grouping of means, and simultaneous selection by the GYT Biplot were implemented. Through the GYT Biplot approach, the two lines, MNC11-1013E-35 and MNC11-1013E-15, were found superior because they combined the traits, grain-yield with the yield components and nutritional traits simultaneously during the cultivation in the Piauí semi-arid zone. However, the MNC11-1052E-3 line was better in the combination of yield and cooking quality than the other lines.

“…Moreover, the GYT two‐way table can be displayed in a biplot, referred to as GYT biplot, which allows visualization of the genotypes' overall superiority as well as their trait profiles (strengths and weaknesses) (Yan & Fregeau‐Reid, 2018; Yan et al., 2019). The GYT procedure has already gained some popularity in multi‐trait selection of various crops (e.g., da Cruz et al., 2020; Faheem et al., 2023; Gholizadeh et al., 2023; Karahan & Akgün, 2020; Kendal, 2020; Ma et al., 2023; Merrick et al., 2020; Mohammadi, 2019; Peixoto et al., 2022; Xu et al., 2021).

Genotype × environment interaction (GE) and unfavorable associations among breeding objectives are the two key challenges in genotype evaluation and selection. Dealing with GE includes utilizing repeatable GE and accommodating nonrepeatable GE, and analytical tools for both steps have been developed in recent years. The genotype by yield × trait (GYT) analysis was also developed to address the issue of genotype selection based on multiple traits. However, a method to integrate both multi‐trial and multi‐trait information has been lacking. The purpose of this study was to fill the gap. Two types of biplots were described and demonstrated, using an oat (Avena sativa L.) dataset as an example. The G + GE biplot of GYT index graphically displays the mean and stability of the genotypes, considering all breeding objectives. The GYT biplot across trials graphically displays the overall superiority and the strengths and weaknesses of the genotypes, after accommodating the nonrepeatable GE. The two types of biplots rank the genotypes in the same order of superiority; they complementarily provide a complete picture of the genotypes and allow confident genotype evaluation, selection, and recommendation.

“…The GYT methodology provides a superiority index (SI) for evaluating genotypes based on all yield–trait combinations and identifies the weaknesses and strengths of each genotype (Mohammadi, 2019). This method for the evaluation of the genotypes based on multiple traits was used in different crops by Yan and Frégeau‐Reid (2018) in oats, Kendal (2019) in durum wheat, Boureima and Abdoua (2019) in sesame, Da et al (2020) in cowpea, Hudzenko et al (2021) in barley, Peixoto et al (2022) in cotton, and Gouveia et al (2020), Gouveia et al (2022) in Urochloa sp. So far, GYT biplot analysis had not been used in rapeseed breeding for examining the relationships between different traits and selecting genotypes based on different traits, and certainly this is the novelty for this paper.…”

The selection based on multiple traits enhances the crop cultivars merit to farmers. In this regard, 19 breeding lines as well as two commercial cultivars were studied using a randomized complete block design (RCBD) with three replications in three locations during the 2020–2021 growing season. In this study, to identify the association among different traits and to select the best rapeseed lines based on multiple traits, genotype × trait (GT) and genotype × yield × trait (GYT) biplot analyses were used. The results showed that using GYT biplot is more efficient than GT biplot. Based on the GYT biplot and superiority index (SI), the breeding lines G16 and G18 were considered as superior genotypes in combination with the agronomical traits, that is, 1000‐seed weight, number of seeds per pod, number of pods per plant, number of lateral branches, plant height, and pod length with seed yield, which represents a genetic gain in rapeseed breeding program. Based on seed yield combination with phenological traits (early maturity), the breeding line G15 was selected as the best one. Moreover, the line G2 was defined as the superior one in combination of seed yield with pod length. The results indicated that there is a potential for simultaneous genetic improvement of the characteristics (i.e., plant height, number of seeds per pod, early maturity) in rapeseed. Generally, the graphical method of the GYT biplot represented an efficient and practical new way to recognize superior genotypes based on multiple traits in rapeseed breeding programs.
