The aim of this work was to evaluate the main quality traits in the parental lines of wheat segregating populations to identify the best for subsequent genetic mapping of the traits. Significant differences (p < 0.001) among wheat genotypes were observed. Many of the examined crosses appeared to be suitable for the purpose, showing differences among parental lines as high as 4.6% for protein content, 6.4% for gluten content, 69 for gluten index, 50 mL for sodium dodecyl sulphate sedimentation volume, and 33.9 g for thousand-kernel weight, whereas differences accounting for 4.8, 2.4, and 7.3 were observed for yellow index, red index and brown index, respectively. The results pointed out that for studying at the same time the quantitative and qualitative features of gluten, the wheat populations derived from Latino x MG29896 and Saragolla x 02-5B-318 could be particularly appropriate. In addition, the latter cross was suitable to deepen the knowledge of yellow index regulation.

Gluten Index

Gluten strength is an important end-use quality factor in durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.], affecting pasta manufacture and cooking quality. The objective of this research was to determine the inheritance and heritability of gluten index in comparison with the widely used SDS-sedimentation (sodium dodecyl sulphate) technique for selection for gluten strength. Seven durum populations were grown in replicated, multi-location, multi-year field trials in Saskatchewan, Canada, during the period 1995 to 2002. Gluten index and SDS-sedimentation volume were determined on all plots after harvest. Both traits were affected by genotype, and to a lesser extent by year or location. Genotype environmental interactions were generally minor. The majority of genotypes in each population had similar relative ranking for gluten index and SDS-sedimentation volume in each environment. Both traits were highly heritable, ranging from 0.80 to 0.97, and both were complexly inherited with estimates of effective factors ranging from 3 to 21. Gluten index and SDS-sedimentation volume were highly correlated, indicating that they are measuring similar aspects of gluten strength. SDS-sedimentation volume was positively associated with protein concentration (r2 = 0.52), but gluten index was not. Therefore, gluten index would be more desirable than SDS-sedimentation volume for use in selection where there are within-trial protein concentration trends.Key words: Gluten strength, SDS-sedimentation, gluten index, heritability, inheritance

Sakin, M. A., Sayaslan, A., Duzdemir, O. and Yuksel, F. 2011. Quality characteristics of registered cultivars and advanced lines of durum wheats grown in different ecological regions of Turkey. Can. J. Plant Sci. 91: 261–271. In this study, pasta-quality-associated characteristics of 25 durum wheat genotypes were investigated. Durum wheat genotypes consisted of 13 advanced experimental lines and 12 registered cultivars that were grown in three different locations of Turkey for 2 yr. Genotype, location, year and their interactions were found to be statistically significant in terms of all investigated quality characteristics. Mean quality parameters for the genotypes varied as follows: yellowberry kernel 1.7–6.1%, pigment content 3.67–8.31 mg kg−1, lipoxygenase (LOX) activity 12.9–27.9 EU g−1, protein content 10.8–11.8% (14% mb), gluten index (GI) 12-61, sodium dodecyl sulphate-sedimentation volume 17.3–28.7 mL, specific sedimentation volume 1.60–2.52 mL. Of the genotypes, 10 contained γ-gliadin 45 and six γ-gliadin 42 proteins. Except for Zenit, none of the registered cultivars and advanced experimental lines investigated in this study were able to meet simultaneously the requirements for high-quality pasta products; yet certain experimental lines prevailing in specific quality characteristics, such as Line-Gdem-2, Line-Gdem-12 and Line-20, may be used for further breeding purposes. The results of this study also imply that grain yield and quality should be taken collectively into consideration in wheat breeding programs.

The sodium dodecyl sulphate (SDS) was applied to six sets of composite eastern Canadian wheats, four from regional registration tests and two from a nitrogen fertility study, both from the 1990 and 1991 seasons. Correlations existed between SDS sedimentation volume and remix bread loaf volume (cm3) only in three of the six sets tested. These correlations were improved when calculated independently from the grain protein concentration. There were no significant correlations among variables for the spring wheat sets from the registration tests. In conclusion, the SDS sedimentation method seems unable to differentiate between eastern Canadian wheats of different remix loaf volumes especially when they have a high grain protein concentration (GPC), and is thus not suitable for use in predicting wheat strength.

Abstract Apricot (Prunus armeniaca L.) is a world-wide highly appreciated fruit, with its attractive colour, soft texture and typical flavour. In the current investigation, 68 apricot accessions collected from Jammu and Kashmir, India were analysed to determine the measure of variation using 12 qualitative and 16 quantitative traits with an aim to identify superior apricot accessions with excellent fruit quality traits. High phenotypic variability was observed among the studied apricot accessions with significant differences among most of the qualitative and quantitative traits. Fruit-related characteristics including fruit weight, fruit length, fruit ratio, fruit firmness, fruit shape, fruit suture, stone weight, kernel weight and stone shape were the most diverse with a high coefficient of variation (>30%). One way analysis of variance showed significant differences (P < 0.0001) among all the quantitative traits. Significant positive and negative correlations were observed between all the agronomically important fruit quality traits. The principal component analysis (PCA) revealed that 75.34% of the variability was defined by the first eight components. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram, based on all traits measured grouped the accessions into two main clusters with several sub-clusters. Both UPGMA dendrogram and PCA scatter plot formed a cluster of 14 accessions, having the highest values regarding most important fruit quality traits such as fruit weight, fruit length and width, fruit ratio, stone weight and kernel weight can be treated as potentially superior accessions. These accessions can be used directly for cultivation and in future apricot breeding programmes. The present findings are promising for genetic resource management, cultivar improvement and commercial applications of apricot in Jammu and Kashmir, India.

In this paper, we followed the kinetics of methyl methacrylate (MMA) through a novel fluorescence method. The real-time measurement results show that in the regime of very low monomer contents, such as a solution containing 0.1 wt% of MMA with respect to water and with the anionic surfactant of sodium dodecyl sulphate (SDS), the kinetic of the miniemulsion could be followed by this embed fluorescence method. The processes of changing from emulsion to miniemulsion with different amount of surfactant and cosurfactant also have been monitored.
