“…However, strong negative correlations between key traits often exist, which make breeding and selection very challenging (Lewis, 2006). Understanding of the genetic variations between and within populations is key for any breeding strategy (Xiao et al, 2008), and it is important to ascertain the variations available in terms of agronomic and plant structure traits (Rubio et al, 2004). Heritability of a trait is important in estimating its response to selection, and genetic improvement of quantitative traits requires reliable estimates of heritability.…”

“…Recently, a genotype by trait (GT) biplot, which is an application of the GGE biplot technique, is becoming an effective tool for exploring multi-trait data (Yan and Kang, 2003). It graphically displays the genotype by trait table as a biplot, and allows the visualization of the associations among traits across the genotypes (Yan and Rajcan, 2002), and trait profile of the genotypes (Ma et al, 2004;Rubio et al, 2004;Yan and Frégeau-Reid, 2008;Yan and Kang, 2003). It also provides information on the usefulness of cultivars for production as well as generates information that helps to detect less important (redundant) traits, and identify those that are appropriate for indirect selection for a target trait.…”

“…It also provides information on the usefulness of cultivars for production as well as generates information that helps to detect less important (redundant) traits, and identify those that are appropriate for indirect selection for a target trait. The GT biplot has been utilized to study trait relations and genotype evaluation in several crop species including soybean (Yan and Rajcan, 2002), white lupin (Rubio et al, 2004), common bean (Hirpa et al, 2013;Gonzalez et al, 2006), cowpea (Oladejo et al, 2011), durum and bread wheat (Akcura, 2011;Reza et al, 2011), and aromatic peppers (Abu et al, 2011).…”

“…Significant intra-specific variations were reported among Ethiopian white lupin landrace accessions (Atnaf et al, 2015b) and also among accessions from other parts of the world (Raman et al, 2014;Rubio et al, 2004) for grain yield, disease resistance and other important agronomic traits. Several researchers studied the relationships among agronomic traits in white lupin (Annicchiarico et al, 2010;Gonzalez-Andres et al, 2007;Rubio et al, 2004).…”

Limited information is available on trait relations and profiles of white lupin landraces in tropical growing conditions including Ethiopia. The objectives of this study were to understand the relationships among traits, and to document trait profile of Ethiopian white lupin landraces. As a component of this study, two sets of experiments were conducted. The first comprehensive experiment that consisted of 143 accessions collected from major lupin growing areas of Ethiopia was evaluated at Merawi and the second experiment that consisted of 12 selected accessions was evaluated across six locations. In both experiments, significant variations were observed among the accessions for most studied traits. Higher heritability and genetic advance as percent of mean was observed for grain yield, indicating the possibility of improving this trait through selection. Genotype by trait biplots captured 55% -66% of the variations due to genotype by trait interactions. Trait association and trait profile biplots were constructed for highland, mid altitude and low land environments, and across all locations. Different patterns of associations and genotype (accession) by trait interactions were observed in different environments. However, genotype by trait biplots consistently indicated that grain yield had positive associations with most of the traits; especially, with number of pods per plant, plant height and seeds per pod. The study identified some accession with desirable performances as good for specific trait and/or trait groups that could be considered as sources of genes for the traits they have best performed. G8 consistently showed higher grain yield, G2 had higher number of branches and higher number of seeds per plant, G7 had more number of pods per plant and larger seed size and G4 produced longer pods. The accessions used in this study were found to be useful sources for genetic variability for future breeding that targets to improve grain yield and other agronomic traits of white lupin in Ethiopia.

“…Improvement of agronomic traits has been the primary objective of breeders/agronomists for many years under variable environments. Breeders have also measured and selected for grain yield and most related traits such as kernel weight, plant height, and other related traits (Link et al, 1999;Garcia del Moral et al, 2003;Maman et al, 2004;Rubio et al, 2004). All these traits are affected by the growing environment as well as by genetic factors, and numerous studies have described the genotype-by-environment (GE) interactions (Humphreys et al, 1994;Doehlert and McMullen, 2000;Doehlert et al, 2001).…”

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.
