Grain protein content and grain yield data were collected from 11 Interstate Wheat Variety Trials (IWVT) and other sources. The level of variation in grain protein content beyond that attributable to covariation in environment and yield was estimated using a generalized linear model. A range of almost 4% in corrected protein content was found among 204 lines tested in IWVT. The Western Australian cv. Tincurrin was approx1% lower in grain protein content than any other line, while Shortim, Sun 43A, QT2200-20, QT2612-1 and Sun 92A were all 1.4-1.7% higher than the pooled mean of 4 control cultivars (Cook, Eagle, Halberd and Oxley). Accessions did not vary significantly in protein content with change in yield. Results from a range of other independent trials confirmed those from IWVT. Wheats genetically capable of producing a higher concentration of protein in their grain at a given yield level came principally from the Sydney University and Queensland breeding programmes, and those producing a lower concentration principally from Victoria and Western Australia. Grain hardness was independent of grain protein content and many low protein hard wheats entering the IWVT fell well outside current international market requirements.

Purpose. To investigate the formation of cereal properties of spelt wheat grain depending on variety and line. Methods. Laboratory, mathematical and statistical, physicochemical. Results. As a result of studies it is found that technological properties of grain significantly vary depending on spelt variety and weather conditions. The protein content in spelt grain ranges from 11.0 to 21.3 % depending on the variety. A very high protein content in spelt grain (over 18.0 %) is in variety Zoria of Ukraine; rather high protein content (16.0–17.9 %) is in varieties Schwabenkorn (17.6 %), NSS 6/01 (17.3 %), Avstraliiska 1 (16.7 %) and LPP 3218 (16.7 %); low protein content (12.0–13.9 %) is in varieties LPP 3435 (13.1 %)and LPP 1224 (13.0 %); very low protein content is in varieties Shvedska 1 (11.0 %) and LPP 3117 (11.5 %); the rest of varieties has this indicator at the level of average – 14.0–15.9 %. Vitreous consistency of the endosperm has corn of varieties Zoria of Ukraine and Avstraliiska 1, semi vitreous consistency has grain of varieties NSS 6/01, Schwabenkorn, Frankenkorn and lines LPP 3218, LPP 3132, LPP 1305, LPP 1197, LPP 3124, LPP 3435, semi floury consistency has Shvedska 1 and LPP 3117. Culinary assessment of rolled spelt grains varies significantly depending on the variety. Total culinary assessment of rolled grain porridge of the spelt ranges from 6,8 to 9,0 points. Origin of spelt variety does not affect this indicator. The highest culinary assessment (8.9–9.0 points) has porridge obtained from grain of the variety Zoria of Ukraine and LPP 3132 line which makes it possible to use its grain to obtain cereal products. The lowest assessment of the porridge has variety Shvedska 1 and lines LPP 1224, LPP 3117 – 6.8–7.7 points. The other varieties have a culinary assessment of the porridge at a level of 8.1–8.8 points. For spelt grain indicator of protein content and grain vitreuesness can be used to evaluate the culinary properties of cereals. Conclusions. As a result of the conducted researches, it is established that Zoria Ukrainy, Schwabenkorn, NSS 6/01, Australian 1 varieties and LPP 3218 line are characterized by high protein content. Hard consistency of endosperm has the grain of Australian 1 and Zoria Ukrainy varieties in which the grain hardness is 73 and 84%, respectively. The origin of spelt wheat variety does not affect the color of cooked porridge. The general culinary evaluation of rolled spelt wheat porridge ranges from 6.8 to 9.0 points. Zoria Ukrainy spelt grain has the highest culinary evaluation which makes it possible to use it to produce cereals. To evaluate the culinary properties of spelt cereals, grain protein content and its hardness can be used.

Understanding the gravity of nutritional significance of rice (Oryza sativa L.) protein, an experiment conducted in Randomized Complete Block Design (RCBD) involving effect of nitrogen (N) rates i.e.,140 kg N/ha, 120 kg N/ha, 100 kg N/ha and 80 kg N/ha on grain protein content, yield parameters and cooking characteristics of polished rice from eight rice genotypes was conducted. N application significantly affected the grain protein content, grain yield, head rice recovery, plant height and effective tillers. In high protein cultivars substantially low to intermediate amylose content and more cooking time was recorded while in low protein counterpart amylose content was comparatively high with low cooking time. Maximum cooking time in polished rice was of 25 min at 180 kg N/ha dose and highest amylose content of about 27% at 80 kg N/ha. Gumminess and hardness of cooked rice and cooking time significantly elevated with increase in N dose. The substantial differences in grain protein content in brown, polished and cooked rice was observed. Cooking revealed the significant increase in protein content ranged from 50%-70% in low protein to high protein genotypes. R-RGM-ATN-47 with highest grain yield of 62.13 q/ha, grain protein content of 10.00 % in polished rice and intermediate amylose appears to be the most promising candidate.

Deficiency of metals, primarily Fe and Zn, affects over half of the world’s population. Human diets dominated by cereal products cause micronutrient malnutrition, which is common in many developing countries where populations depend heavily on staple grain crops such as wheat, maize, and rice. Biofortification is one of the most effective approaches to alleviate malnutrition. Genetically stable mutant spring wheat lines (M7 generation) produced via 100 or 200 Gy gamma treatments to broaden genetic variation for grain nutrients were analyzed for nutritionally important minerals (Ca, Fe, and Zn), their bioavailability, and grain protein content (GPC). Variation was 172.3–883.0 mg/kg for Ca, 40.9–89.0 mg/kg for Fe, and 22.2–89.6 mg/kg for Zn. In mutant lines, among the investigated minerals, the highest increases in concentrations were observed in Fe, Zn, and Ca when compared to the parental cultivar Zhenis. Some mutant lines, mostly in the 100 Gy-derived germplasm, had more than two-fold higher Fe, Zn, and Ca concentrations, lower phytic acid concentration (1.4–2.1-fold), and 6.5–7% higher grain protein content compared to the parent. Variation was detected for the molar ratios of Ca:Phy, Phy:Fe, and Phy:Zn (1.27–10.41, 1.40–5.32, and 1.78–11.78, respectively). The results of this study show how genetic variation generated through radiation can be useful to achieve nutrient biofortification of crops to overcome human malnutrition.
