Dough Properties

Fifty-four durum wheat (Triticum durum) genotypes entered into the 1995, 1996 and 1997 Co-operative Tests were evaluated for gluten strength characteristics using the sodium dodecyl sulphate (SDS) sedimentation test, the gluten index (GI) test, and physical dough tests including farinograph (high and low adsorption), mixograph, alveograph and extensigraph. Baking quality was evaluated for bread prepared by the Canadian short process (CSP), a short mechanical dough mixing process, and pasta quality was evaluated for spaghetti dried at both low (40°C) and high (70°C) temperatures. The effect of genotype on physical dough measurements, baking quality and spaghetti cooking quality was then determined. SDS sedimentation, GI, pasta dough farinograph (low absorption), bread dough farinograph (high absorption), extensigraph and alveograph measurements were interrelated. When baked by the CSP, the strongest genotypes exhibited mixing times and mixing energies similar to or greater than good quality bread wheat (Triticum aestivum). Although loaf volume (LV) was positively correlated to gluten strength indicators, the strongest genotypes still exhibited only about 85% of the LV expected of good-quality bread wheat of comparable protein content. Baking quality however, was not related to pasta cooking quality, and, therefore, there is potential to breed for dual-purpose durum cultivars, which combine improved baking properties and good pasta cooking quality.

Processing Properties

Durum wheat (Triticum turgidum ssp. durum) is typically used to produce pasta. In some parts of the world, it is used to make bread but with inferior loaf volume and texture compared with common wheat bread. This study describes the effect on technological properties of pasta and bread made from durum wheat cv. Svevo (recurrent parent (S), HMW-GS null, 7+8) and two isogenic genotypes carrying pairs of additional subunits 5+10 (S 5+10) or 2+12 (S 2+12), normally present at the Glu-D1 locus in bread wheat. The semolina was re-ground to flour, mixed in various proportions with bakers flour and used to prepare loaves. The dough properties of the S 5+10 line were markedly different from Svevo, having over-strong, stable dough, low wet gluten and elasticity; S 2+12 also displayed stronger dough. Pasta prepared from these genotypes showed lower cooked firmness (adjusted for protein differences), ranked Svevo > S 5+10 = S 2+12. There were no other differences in pasta cooking quality. Bread loaf volume and loaf score decreased as more bakers flour was replaced by durum flour, but the decline varied with the genetic material and dosage. The greatest reduction in loaf volume occurred using S 5+10 and the least with S 2+12, which was similar to Svevo. Bake score was reduced with S 5+10 only. The best loaf was made using Svevo. This work shows that it is possible to manipulate the processing properties of pasta and durum–bread-wheat blends by altering the glutenin subunit composition. This represents an efficient tool to finely manipulate gluten quality in durum wheat.

The sodium dodecyl sulfate (SDS) sedimentation test was assessed as a screening procedure for durum wheat gluten strength. Thirty durum wheat lines possessing a wide range in gluten strength and spaghetti cooking quality were characterized for wheat protein, SDS-sedimentation value, micromixograph development time, and spaghetti cooking quality at optimum time and after overcooking for 10 min. A statistical analysis revealed that mixograph development time and the SDS-sedimentation test were both able to account satisfactorily for variations in gluten strength. However, SDS-sedimentation test was able to differentiate over a narrower range. The SDS-sedimentation test and wheat protein together accounted for over 40% of the variability in cooking quality at opimum time and after overcooking. These data suggest that screening tests based on the SDS-sedimentation test and wheat protein would be adequate for comparing durum wheats for gluten strength and spaghetti cooking quality.

SummaryTwenty-five winter wheat varieties and breeders' lines including hard and soft texture, good or poor bread and biscuit-making types were grown at two locations in the U.K. in 1977 to provide the test samples. Small-scale tests of bread-making quality including extensometer, sodium dodecyl sulphate (SDS) sedimentation volume, residue protein, urea dispersible protein and Pelshenke tests, were compared with loaf volumes and loaf scores.Averaged over the two sites, a modified extensometer test and the SDS test gave the closest correlation with loaf volume and loaf score and were only poorly correlated with Hagberg Falling Number and percentage protein. The SDS test gave the closest correlation between sites followed by the extensometer readings; loaf volume and score had much lower values. The SDS values and extensometer readings give a better measure of the genetic differences in protein quality of varieties than loaf volume and score, being less affected by growing conditions. With its small sample size and high throughput, the SDS sedimentation volume is likely to be the most useful screening test for wheat breeding programmes.

The results of three-year trials (1999 to 2001) conducted with six winter wheat varieties in which was studied the grain yield and parameters of technological quality. Varieties of wheat come from four different localities of the Czech Republic. The most favourable weather conditions, a lot of precipitation and high temperature in the course of ripening from three years were proved in the year 2000. The best grain yield were in 2001 (average of sites 8.84 t/ha) and variety Semper, worst quality, had the highest grain yield of 9.17 t/ha, the least grain yield had Sulamit, best quality (7.94 t/ha). The laboratory analysis revealed negative correlation between grain yield and baking quality. The number of statistically highly significant correlations among bread-making quality parameters too.The negative correlation was of grain yield and grain volume mass (P < 0.05), Zeleny test and protein content taken as a whole for three years (P < 0.01). The correlation of loaf volume, which is the traits of baking quality and Zeleny test (r = 0.6016**), protein content (r = 0.5932**), dough stability (r = 0.2898**) and flour water absorption (r = 0.3632**) was positive (P < 0.01).

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

Lines of durum wheat (Triticum turgidum L.) were studied for glume color, gluten strength as determined by micromixograph and sodium-dodecyl-sulphate (SDS) sedimentation methods, and banding of gliadin proteins by polyacrylamide gel electrophoresis. The results indicated a linkage of factors controlling glume color and gliadin proteins. There also appeared to be an association of these two characteristics with gluten strength.

Yield Losses

In southeastern Australia, Fusarium crown rot, caused by Fusarium culmorum or F. pseudograminearum, is an increasingly important disease of cereals. Because in-crop control options are limited, it is important for growers to know prior to planting which fields are at risk of yield loss from crown rot. Understanding the relationships between crown rot inoculum and yield loss would assist in assessing the risk of yield loss from crown rot in fields prior to planting. Thirty-five data sets from crown rot management experiments conducted in the states of South Australia and Victoria during the years 2005 to 2010 were examined. Relationships between Fusarium spp. DNA concentrations (inoculum) in soil samples taken prior to planting and disease development and grain yield were evaluated in seasons with contrasting seasonal rainfall. F. culmorum and F. pseudograminearum DNA concentrations in soil prior to planting were found to be positively related to crown rot expression (stem browning and whiteheads) and negatively related to grain yield of durum wheat, bread wheat, and barley. Losses from crown rot were greatest when rainfall during September and October (crop maturation) was below the long-term average. Losses from crown rot were greater in durum wheat than bread wheat and least in barley. Yield losses from F. pseudograminearum were similar to yield losses from F. culmorum. Yield loss patterns were consistent across experiments and between states; therefore, it is reasonable to expect that similar relationships will occur over broad geographic areas. This suggests that quantitative polymerase chain reaction technology and soil sampling could be powerful tools for assessing crown rot inoculum concentrations prior to planting and predicting the risk of yield loss from crown rot wherever this disease is an issue.
