“…The genotype by trait (GT) and genotype by yield by trait (GYT) graphical analysis are among these methods that provide graphical and clear images of trait and genotype relationships. The GT biplot analysis has been used for this purpose in some crops such as soybean (Yan & Rajcan, 2002 ), lupin (Rubio et al, 2004 ), rapeseed (Dehghani et al, 2008 ), corn (Santana et al, 2021 ; Santos et al, 2021 ; Shojaei et al, 2020 ), wheat (Zulfiqar et al, 2021 ), and sorghum (Mukondwa et al, 2021 ). A potential constraint of the GT biplot method is that it may fail to explain most of the variation and therefore fail to display all patterns of the data and this is most likely to occur with large datasets, small main effects, and complex interactions.…”

Sunflower is one of the most important oilseed plants in the world and its oil has nutritional and high economic value. Selection of high‐yielding hybrids is important in sunflower breeding. In this regard, 11 new hybrids along with four cultivars were evaluated in a randomized complete block design with four replications during the 2018–2020 growing seasons. The phenological and agronomic traits including days to flowering, days to ripening, plant height, stem diameter, head diameter, seed number per head, thousand‐seed weight, oil content, and seed yield were measured. In this study, the methods of genotype × trait (GT) and genotype × yield × trait biplot (GYT) were used to identify interrelationships between different traits and to select the best sunflower hybrids based on multiple traits. According to the results, GYT biplot method was more efficient compared to the GT biplot method. Considering both superiority index (SI) and GYT biplot, the genotypes G8, G11, G5, and G3 were superior in terms of agronomical attributes such as flowering and maturity times, stem and head diameter, plant height, thousand‐seed weight, and seed number per head in close relationship with grain yield. Oil content of the hybrids G8, G11, G5, and G3 was 47.9%, 46.4%, 45.8%, and 46.3%, respectively. The results indicated that there is a potential for simultaneous genetic improvement of the characteristics (i.e., plant height, thousand‐seed weight, seed number per head, early maturity) in sunflower. Overall, the GYT graphical biplot method provides a practical and efficient new approach for the identification of suitable hybrids according to the set of intended characteristics in sunflower improvement under multi‐years or multi‐locations.

“…A recent approach for multitrait genotype selection combines GT biplot and yield to become a genotype by yield*trait biplot, and this method is useful to obtain information about yield relative to other breeding targets (Yan and Fregeau-Reid 2018). The GT biplot analysis has been applied to other crops such as rice (Sharifi and Ebadi 2016), sorghum (Mukondwa et al 2020), and corn (Orhun 2020;Shojaei et al 2020). Unfortunately, there has been limited study into how GT biplot analysis is used to identify potential hybrids based on corn flour nutritional values by plant breeding approaches.…”

Abstract. Humam BK, Suwarno WB, Azrai M, Makkulawu AT, Efendi R. 2023. Variability of kernel morphological and flour physicochemical properties in tropical dent corn hybrids. Biodiversitas 24: 1600-1609. Corn is an important crop worldwide for food, feed, and industry. The aims of this study were to study kernel morphological and corn flour physicochemical properties and hybrids selection according to nutritional values for food industries. Plant materials were 15 test hybrids and four check varieties, namely RK457, RK57, BISI18, and NASA29. Kernel morphological and corn flour physicochemical variations are influenced by kernel type. All dent hybrids had 40/0 mesh corn flour yielded significantly higher compared to NASA29. °Dent scores were negatively correlated to 40/0 mesh corn flour yields. The total and soluble carbohydrates of dent corn flour hybrids are significantly higher compared to semi-dent and semi-flint corn flour hybrids. According to corn flour nutritional values in polygon GT biplot analysis, dent hybrids had relatively high starch, total carbohydrate, and soluble carbohydrate contents. Semi-dent hybrids had relatively high moisture, crude protein, and total ash contents. Semi-flint hybrid had relatively high crude fat and crude fiber contents. Cluster-2 was dominated by dent hybrids according to the fuzzy clustering method and selected as potential hybrids. MSM53 was the female parent of dent hybrids in cluster-2. Potential hybrids could be evaluated further by corn flour functional properties analysis.

“…Among the different methods, the genotype × trait (GT) and genotype × yield × trait (GYT) biplot analyses are advantageous graphical tools that prepare efficient overview of different traits and genotypes relationships. The GT biplot has previously been used in different crops to determine the association between different traits and genotypes such as rapeseed (Dehghani et al, 2008 ), sorghum (Mukondwa et al, 2021 ), corn (Santana, Flores, et al, 2021 ; Santos et al, 2021 ; Shojaei et al, 2020 ), white soybean (Yan & Rajcan, 2002 ), white lupin (Rubio et al, 2004 ), wheat (Zulfiqar et al, 2021 ), papaya (Santana, Ramos, et al, 2021 ), and tomato (Ene et al, 2022 ).…”

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.
