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

Abstract

SUMMARYGrain yield is very important and complicated trait in spring barley breeding and rely upon combination varied plant traits (agronomic and quality). For this reason, a real barley breeding program necessaries an appropriate mentality of the relationships between grain yield and traits. The aim of study was evaluate the relationship of grain yield and other traits of 25 spring barley genotypes in one location during two years by GGE Biplot analysis. The experiments were performed according to a complete randomized block design with three replications. Factors (G, GE, and GEI) were found to be highly significant (P < 0.01) for grain yield. GGE Biplot indicated that three group were occurred among traits, first group (thousand grain weight, protein content, crude cellulose and cold damage), second group (hectoliter weight, lodging, plant height and heading time), third group (grain yield and seed humidity). Moreover, the study showed that negative correlation was found between grain yield and traits without seed humidity. The results of AMMI model and GGE Biplot indicated that G12, G13, G16 and G18 is proper for grain yield, G2, G6, G19 and G1 desirable origin for quality and other agronomic traits to select for advance stage and use in barley breeding program.

Selection of Early Soybean Inbred Lines Using Multiple Indices

“…Several studies considering the genotype ´ environment interaction in many crop species are presented in the literature (Kendal, 2015;Kendal and Sener, 2015;Dogan et al, 2016;. Several studies considering the genotype ´ environment interaction in many crop species are presented in the literature (Kendal, 2015;Kendal and Sener, 2015;Dogan et al, 2016;.…”

“…The genotype ´ environment interaction is often reported for different traits in soybean (Carvalho et al, 2002a;Lima et al, 2008;Vasconcelos et al, 2010;Marques et al, 2011;Barros et al, 2012;Bueno et al, 2013;Silva et al, 2015;Soares et al, 2015) and other crop species, like barley (Hordeum vulgare L.), triticale (´Triticosecale Wittm. ex A. Camus), and wheat (Triticum aestivum L.) (Kendal, 2015;Kendal and Sener, 2015;Dogan et al, 2016;. When the existence of interaction is verified, a strategy that can be adopted is the adaptability and stability analysis through the genotype + genotype ´ environment (GGE) biplot method.…”

Grain Yield and Yield Components of Winter Barley

“…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). Malting barley is expected to have 1000 grain weight of 40 and 46 g and test weight of 68 to 75 kg/hl (Paunović et al, 2006).…”

INFLUENCE OF NITROGEN FERTILIZATION LEVELS ON GRAIN YIELD AND ITS COMPONENTS IN BARLEY (Hordeum vulgare L.)

“…The center of the concentric circles (i.e., ideal dose) was the AEA in the positive direction. Doses located closer to the ideal dose were more desirable than others (Yan &Tinker, 2006;Dogan et al, 2016). The result demonstrated that N4 was ideal application dose in the both season, as it was in the center circle for the ideal doses and on the AEA (Fig.…”

“…Also regression analysis was done by this program. On the other hand; GT biplot analyses were used to determine the differences among application nitrogen doses and crop characteristics and cultivar crop characteristics in two growing seasons (Dogan et al 2016;Kilic, 2016). GGE biplot analysis also allows comparison amongst nitrogen doses in terms of their discriminating ability and representativeness.…”
