STABILITY OF A CANDIDATE AND CULTIVARS (Hordeum vulgare L) BY GGE BIPLOT ANALYSIS OF MULTI-ENVIRONMENT YIELD TRIAL IN SPRING BARLEY

Abstract

SUMMARYThe explication of candidate line and new varieties is uncomfortable the affect of genotype-by-environment interaction (GEI). The AMMI (Additive main effects and multiplicative interaction) analysis and GEI is making to estimation grain yield and understands GxE interaction patterns by researches as differential ranking of variety yields in multi-environment trials. So, a candidate of release and three spring barley varieties which registered in different years were reclaimed at seven environments. The experiments were performed according to a complete randomized block design with four replications. The stability and superiority of genotypes for yield was determined using AMMI and GGE biplot analysis. Factors (G, GE, and GEI) were found to be highly significant (P < 0.01) for grain yield. AMMI analysis indicated that the major contributions to treatment sum of squares were environments (79.4%), GE (13.9%) and genotypes (6.4%), respectively, suggesting that grain yield of genotypes were effected environmental conditions. The GGE biplot indicated that PCA 1 and PCA 2 axes (Principal component) were significant as P<0.01 and supplied to 86.3% of the complete GxE interaction. The GGE biplot indicated that four mega-environment were occured in terms of varieties. The varieties and candidate line took part in an independent mega-environment. On the other hand, Candidate line showed general adaptability (E1, E2, E4, E5 and E7), while Altikat and Sur 93 showed specific adaptation to E3 and E6 respectively. According to both techniques, especially Sahin 91, Sur 93 and Altikat came forward with low yielding, while candidate line with high yielding, stability and general adaptability. Statistical results indicated that AMMI and GGE biplot are informative techniques to compare varieties with candidate lines to discover general stability, adaptation pattern for practical recommendations.

Identifying of Relationship Between Traits and Grain Yield in Spring Barley by Gge Biplot Analysis

“…The high addition of environment effects showed that there were important differences between growing season for grain yield. The results of AMMI analysis showed similar results of Kendal and Dogan(2015) and Yan and Rajcan (2002), reported that the environment effect had the highest effect than other factors on barley and soybean grain yield respectively.…”

“…Gauch & Zobel (1997), Kendal and Dogan(2015), suggested that the AMMI model is the most accurate a model because it can predict using the first two IPCAs.…”

Comparing durum wheat cultivars by genotype × yield ×trait and genotype × trait biplot method

“…By dividing the figure with thick axes from the center and separating each zone with two thick lines, sectors are obtained and indicated by correlative numbers (1, 2, 3, etc). If the genotypes and properties are located in the same sector when starting from the lower right part of the graph, they are closely related (Yan and Tinker, 2006;Kendal and Dogan, 2015). According to this description, Figure 1C is divided into four sectors, and different traits are associated with different cultivars in each sector.…”

“…Approximately half of the durum wheat production in Turkey takes place in the Southeastern Anatolia Region, known as the central origin of durum wheat. Since the agroecological environmental conditions of this region are very suitable for wheat production, the highest quality durum wheat has been produced in this region; this situation has been established by many researchers (Kendal and Dogan, 2015;Kilic et al, 2017;Tekdal and Kendal, 2018).…”

Grain Yield and Yield Components of Winter Barley

“…Yields considerably vary primarily as a result of agroecological conditions during the growing season (Đekić et al, 2014). Experimental research needs to be carried out over multiple environment trials in order to identify and analyse the major factors that are responsible for genotype adaptation and final selection (Popovic at al., 2011Kendal, E and Dogan, Y. (2015), Dogan et al 2016).…”
