“…According to the mean of these analyses, there were differences between the genotype of at least one standard deviation for the industrial quality variables, with the exception of total protein, viscosity and wort colour. Similar results were found under irrigated conditions in the Brazilian savanna, by Evans et al and Verma and Sarkar , indicating the existence of probable genotypic variability among the 38 genotypes of barley that were evaluated.…”

The Brazilian savanna has the potential to support the national demand for barley providing an opportunity to the agricultural business in the region. The barley breeding program of Embrapa Cerrados pursues the selection of superior genotypes, adapted to the savanna conditions, with industrial quality and high grain yields. This work sought to characterise and quantify the genetic variability of 38 elite genotypes of irrigated barley in the Brazilian savanna from industrial grade traits, verifying the degree of association between quality characters and analysing the genetic distance from the ideotype. Twelve traits of malting quality were evaluated in two environments of the Distrito Federal. A descriptive analysis of the data was performed, the genetic dissimilarity coefficients were estimated between each genotype pair based on the Mean Euclidean Distance, the genotype-ideotype distance index, the Pearson correlation and the relative contribution of each trait to Singh's genetic diversity of evaluated traits. There were dependency relationships between malting traits for the evaluated environments. Such associations facilitate the indirect selection of genotypes, increasing the efficiency of the breeding program. The use of selection indices allows the choice of promising genotypes that can be explored in blocks of crosses to maximise heterotic effects and genetic complementarity in the genetic breeding program of irrigated barley in the Brazilian savanna.Additional supporting information may be found online in the Supporting Information section at the end of the article.Genetic variability of irrigated barley in savanna environments based on malting quality

“…In the evaluated set of genotypes, a strong negative correlation was detected between the Kolbach index and the content of β-glucans in wort (r = -0.72). A similar correlation was also found by Jin et al (2011) and Amabile et al (2014).…”

“…The values ranged from 27.3 to 62.9%. Amabile et al (2014) reported the range of values of the Kolbach index in a set of 30 malting two-row and six-row barley mainly from the area of South America in the range of 38.7-64.8%. In the observed set, the group from South America and Australia (35.9%) together with the group from the Middle East and Africa (36.6%) differed statistically significantly in this parameter from the other groups (Table 7).…”

A set of 92 genetic resources of spring barley split into groups according to the areas of origin was studied in terms of grain malting quality. The following malting parameters were monitored in this study: nitrogen content in barley grain, malt extract, relative extract at 45 °C, Kolbach index, diastatic power, apparent final attenuation, friability, β-glucans in wort, haze of wort measured at the angles of 15° and 90°. In the studied set, the largest variability was found in the haze of wort (90°), the smallest in the apparent final attenuation. The optimal values of the extract content in the malt dry matter according to the malting quality index were only detected in the genotypes originating from Europe. The group of the genetic resources from South America and Australia, together with the genotypes from the Middle East and Africa, differed statistically significantly in the values of the Kolbach index from other groups. The two-row genotypes differed statistically significantly in the values of the malt extract content, relative extract at 45 °C, Kolbach index, diastatic power, friability and β-glucan content in wort. Although the European and non-European groups differed in a number of traits, the non-European groups also included genetic resources that in their malting parameters approached or equaled the European malting varieties (such as Psaknon). In this study, several significant correlations were found; the strongest correlations were between friability and malt extract (r = 0.85), friability and Kolbach index (r = 0.84).

“…Barley is one of the best cereals for cultivation in dry and semi-dry areas. It is the world's fourth most important cereal in terms of production, (after wheat, rice, and maize) and is the second most important (after wheat) in the Middle East and North Africa (Amabile et al, 2014). The effective management of barley production is complicated by a number of contingency factors, which makes it almost unpredictable.…”

“…It is important to study the divergence and genetic relationships among the barley accessions since the characterisation of genetic variability helps to identify better genotypes which could be used in hybridisations as parents and improves quality of agricultural products (Amabile et al, 2014). The use of factor analysis in this context can help to reduce a large set of traits to a smaller but meaningful set of traits, thereby allowing researchers and practitioner to identify trait that contributes to maximum variability since genetic improvements largely depends on the magnitude of genetic variation (Parvathaneni et al, 2011).…”

This paper aims to demonstrate the usefulness of factor analysis for managing barley trials. It shows whether the relationship between barley yield parameters and morphological characters were affected by genotype and environment. The objectives of this study were to determine whether or not the interrelationship between barley yield parameters (total plant yield, grain yield, straw yield and thousand grain weight), and the morphological characters (vegetative duration, plant height, length of growing season and leafiness) was stable in each hybrid (hybrid 1, hybrid 2 and hybrid 3) and each of two areas in Syria by using factor analysis. The study also aimed to ascertain whether the relationship between yield parameters and morphological characters was affected by genotype environment interaction. There were three hybrids in each of the two Syrian areas: Tel Hadya and Breda. Each hybrid had 102 families. Correlation and factor analysis indicated that the interrelationship for yield parameters, except TGW, was stable, while the interrelationship between morphological characters was not stable. Factor analysis was applied to barley breeding data to determine the relationships between yield parameters and morphological characters. The results demonstrate that this relationship was stable in Tal Hadya, but not stable in Breda. The genotype and the environment influenced the relationship between yield parameters and morphological characters. Consequently, the relationship between yield parameters and morphological characters will not be suitable for forecasting yield.
