Hagberg Falling Number

The difference between the bread wheat and feed wheat prices in the UK (the premium) is an important influence on behaviour throughout the entire grain chain. The aim of the present study was to quantify the influence of grain quality and other factors on interannual variation in the premium calculated as a proportion of the feed price. A hypothetical model of the UK wheat economy was devised, appropriate annual national data from 1982 to 2000 were collected for each component and multiple regression was used to develop a statistical model for the premium.The statistical model included livestock numbers (calculated as pig equivalents), Hagberg falling number and wheat stocks, which together explained 0·80 of the interannual variation in the premium. A high premium was associated with high livestock numbers, low Hagberg falling number and low wheat stocks. These variables were included in the hypothetical model because: livestock numbers represent demand for feed wheat; Hagberg falling number is a quality criterion for purchase of bread wheat with a low value indicating poor quality and thus a smaller supply of bread wheat; wheat stocks are one of the sources of supply of wheat. It was concluded that of the 16 supply, demand or price variables in the hypothetical model the main variables associated with the premium from 1982 to 2000 were demand for feed wheat, quality of the wheat harvest and carry-over of wheat from the previous harvest.

Favorable Conditions

Waterlogging stress is one of the abiotic factors which causes damage to crops affecting yield components and grain quality of wheat and barley. On the other hand, Fusarium poae is one of the most common Fusarium species isolated from wheat and barley. The aim of this study was to evaluate the effects of waterlogging and F. poae on disease parameters, yield components and grain quality of durum and bread wheat and barley. The experiment was carried out using pots under greenhouse conditions. Four treatments were applied: control/control (W0F0), control/F. poae (W0F1), waterlogging/control (W1F0) and waterlogging/F. poae (W1F1). The results showed that incidence, severity and FHB index of F. poae were higher in W0F1 compared to W1F1 suggesting that waterlogging treatment would be generating no favorable conditions for fungal growth. Therefore, yield components and grain composition and quality were significantly affected by the Fusarium presence and waterlogging treatment which could induce changes in parameters mainly related to the industrial quality of wheat and barley. These results highlight the behavior of wheat and barley under the combination of abiotic and biotic stress.

Range Of Variation

It is known that the breeding process is in a great need for fast methods, working on minimal weights of experimental material and revealing the qualitative potential of the varieties. For this purpose, in order to get rid of unpromising numbers, the laboratory assessments widely use a sedimentation analysis, this type of analysis being the main one at the primary stages of breeding and when estimating winter wheat in the pre-harvesting period. The purpose of the current study was to identify the most valuable genotypes in seed plots by sedimentation analysis to optimize the breeding process of winter bread wheat for grain quality. The sedimentation index was estimated by the method using a 2% surfactant (SAS) solution of the sodium dodecyl sulfate (SDS) and 9.4% lactic acid. Gluten content and its quality, volumetric bread yield and falling number were assessed according to generally accepted methods. For the most accurate interpretation of the study results there has been used a one-way analysis of variance. The range of variation of the sedimentation index in the seed plot of CVT was 35–57 ml (2017); 50–83 ml (2018); 56–84 ml (2019); in KP-1 it was 44–95 ml (there were analyzed 945 samples); in KP-2 it was 50–94 ml (there were analyzed 100 samples). Inthe studied seed plot of CVT, which was laid fallow, 25 of 36 variety samples were very strong in quality; 7 ones were strong; 4 ones were medium; there were not identified any satisfactory and weak samples. As for the seed plot KP-2, 88 of 100 were very strong, 11 ones were strong and only one sample was average in quality. In the seed plot KP-1 480 of 945 were very strong (51%); 440 samples were strong (46%), and only 3% (25 pieces) were average in quality; there were not identified any satisfactory and weak samples.

The current paper has presented the study results of SDS-sedimentation and grain quality indicators of the winter bread wheat varieties in an interstation variety testing from the research institutions of the Russian Federation, Ukraine and France. The research work was carried out in 2017–2019 in the field of the laboratory for breeding winter bread wheat, the forecrop was maize for grain. The purpose of the research was to estimate SDS-sedimentation, protein percentage in grain, quantity and quality of gluten in the winter bread wheat varieties of interstation variety testing, for the subsequent introduction of the best samples in the breeding process aimed at improving grain quality. Grain quality indicators of the winter bread wheat varieties were identified in the laboratory for biochemical estimation of breeding material and grain quality using IR spectroscopy on ‘SpektraStar 2200’ analyzer. There was established that according to the SDS-sedimentation most of the samples corresponded to strong wheat (50–63 ml). There have been identified the genotypes with the highest values of this trait, such as ‘Shef’ (58 ml), ‘Nakhodka’ (59 ml) and ‘Don 107’ (61 ml). The largest gluten content in grain was identified in the varieties ‘Don 107’, ‘Shef’, ‘Kavalerka’, ‘Timiryazevka 150’ and ‘Nakhodka’ (25.5–26.2%). The largest protein percentage in grain has been identified in the varieties ‘Don 107’, ‘Shef’, ‘Aksinya’, ‘Nakhodka’ and ‘Timiryazevka 150’ (12.5-12.8%). The varieties ‘Don 107’, ‘Shef’, ‘Nakhodka’ and ‘Timiryazevka 150’ were identified according to the studied traits and were recommended to be involved in the breeding process as parental forms.
