Winter Triticale

The aim of the study is to characterize winter triticale samples by protein content in grain and productivity, to identify sources of high protein content and high grain yield for use in breeding process. Experimental work was carried out in the conditions of Tatarstan Republic in 2013-2017. The collection of 93 varieties of winter triticale of Russian selection, obtained from the Federal Research Center “All-Russian Institute of Plant Genetic Resources"(VIR) was evaluated in field trials. Wide genetic diversity of the studied gene pool was demonstrated by grain protein content (11.69...16.15 %) and grain yield (277...579 g/m2). Protein content and grain yield were mostly determined by the growing conditions – the factor “year” (58.1 % and 61.8 %, respectively), with a relatively small share of the factor “genotype” (23.9 % and 15.4 %, respectively). Significant variation in the values of the studied indicators, both by genotype and by year, was observed. There were identified 19 sources of high protein content in grain (over 14.5 %) and 17 sources of high grain yield (over 510 g/m2), which showed a significant excess of the standard Bashkirskaya korotkostebelnaya. A group of samples with a relatively high protein content (13.8 ... 14.1 %) and yield higher than the average value (450...500 g/m2) was identified. The highest breeding value among the sources of high yield was shown by samples Zimogor, Kornet, Privada, Vodoley, 3/9 oh Ag 4418, and among the sources of high protein content – Kurskaya stepnaya, Mir, Student, Svyatozar. The listed variety samples additionally possessed a complex of positive features: high ear productivity, high full-scale weight and large grains. In varieties Dokuchaevsky 8 and Privada there was noted a favorable combination of significantly high levels of yield (542 and 527 g/m2, respectively) and protein content in the grain (14.28 and 13.93 %, respectively). The finding of a reliable moderate negative correlation (r = -0.682) between yield and grain protein content indicates that grain protein content can be increased by breeding methods at relatively high or medium yields of varieties.

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.

Four field experiments were conducted over 2 years and at 2 sites under irrigation and with high soil fertility in north-eastern Spain. Two 6-rowed barley varieties, 3 spring triticales, and 2 winter triticales were evaluated for grain yield and for forage and grain production in the same cropping season. Forage was cut at the first node detectable stage and grain was harvested at ripening in both cut and uncut plots. Forage and grain yields did not differ significantly between species. Forage yield was positively and strongly related to the time between sowing and cutting. Forage quality and grain protein content were similar in barley, spring triticale, and winter triticale. Forage crude protein averaged 25·3%, digestible crude protein 19·4%, and acid detergent fibre 21·9%. Grain protein content averaged 15·4%. The reduction in grain yield caused by clipping ranged from 7 to 70% in barley, 10 to 21% in spring triticale, and 8 to 24% in winter triticale. Grain yield after cutting decreased drastically when the thermal time between cutting and physiological maturity was lower than 1000 growing degree-days (GDD), being independent of this duration for values >1100 GDD. Reductions in grain yield after forage removal were caused mainly by reductions in grain weight. A strong relationship appeared between grain yield in the uncut treatment and grain yield after forage removal, suggesting that breeding for dual purpose could take advantage of the efforts made to increase grain yield potential.

AbstractProtein energy malnutrition (PEM) is prevalent in south-east Asian countries including India. Breeding and introduction of grain protein-rich varieties of legumes such as dolichos bean is considered as cost-effective approach to combat PEM. Exploitation of genetic variability within germplasm accessions (GAs) and/or breeding populations is the short-term strategy for identification and delivery of protein-rich dolichos bean cultivars to cater to the immediate needs of the farmers and target population. A set of 118 dolichos bean genotypes consisting of 96 GAs and 20 advanced breeding lines (ABLs) and two released varieties (RVs) was field evaluated in augmented deign for dry grain yield per plant and their grain protein contents were estimated. The grain protein content among the genotypes ranged from 18.82 to 24.5% with a mean of 21.73%. The magnitude of estimates of absolute range, standardized range, and phenotypic coefficient of variation (PCV) for grain protein content was higher among GAs than those among ABLs + RVs. However, average grain protein contents of GAs were comparable to those of ABLs + RVs. Nearly 50% of the genotypes (mostly GAs) had significantly higher grain protein content than those of RVs, HA 3 and HA 4. The grain protein contents of the genotypes were poorly correlated with grain yield per plant. These results are discussed in relation to strategies to breed grain protein-rich dolichos bean cultivars.

The objective of this work was to evaluate the effects of selection for high protein on seed physiological quality and grain yield of soybean. Four populations of BC1F4 and four of F4, each from a cross between a commercial variety and a line bearing high protein seeds, were used. The high protein content selection has a tendency to affect negatively the seed physiological quality. Estimates of correlation coefficients between protein content and grain yield were mostly negative but varied among populations. It is possible to obtain lines with high protein content, keeping the grain yield and the seed physiological quality of their respective recurrent progenitors.

Supplementary Irrigation

On the Darling Downs the growth and yield of a semi-dwarf wheat (cv. Oxley) under supplementary irrigation was increased by the application of up to 400 kg/ha of nitrogen (N) at planting. Nitrogen at 50 or 100 kg/ha applied at the boot stage to supplement 100 kg/ha applied at planting increased grain yield by 459 and 478 kg/ha, respectively. However, yields were still below those where all the N was applied at planting. In contrast, supplementary N (0, 25, 50 or 100 kg/ha) at flowering or after flowering generally did not increase grain yield. One exception to this was where only 50 kg/ha was applied at planting; an additional 100 kg/ha at flowering increased grain yield by 602 kg/ha. Applied at planting, more than 200 kg/ha of N was needed to produce premium grade wheat (i.e. protein content above 11.4%). To achieve this protein content where 100 kg/ha had been applied at planting an additional 100 kg/ha was needed at the boot stage or 50 kg/ha at flowering. Applied after flowering, up to 100 kg/ha of additional N produced wheat of a protein content too low to attract a premium payment. A similar quantity of N was assimilated whether the entire N application was applied at planting or where the application was split between planting and boot or flowering. Less N was assimilated when the application was split between planting and after flowering. More N was assimilated from soil than from foliar applications at the boot stage. Soil and foliar applications were equally effective at flowering in increasing the amount of N assimilated as well as the grain protein content. However, after flowering foliar application was the more effective method. The application of N at flowering to increase the protein content of this semi-dwarf cultivar is not an attractive commercial practice. The price ratio of premium to Australian Standard White wheat in recent years (<1.071 ) is less than that needed (1.0954-1.3013) to justify splitting the N application to lift grain protein content above 11.4% at the expense of yield.

The experimental design was split-plot in randomized complete block design with three replications. Results showed that positive significant effect on plant height, number of spike/m2, spike length; number of grain per spike, grain yield per unit area in both seasons and grain protein content in one season were achieved by application of N and the micronutrients. Whoever, the highest significant in the above mentioned characters was obtained either by application the highest N levels (100kg N /fed.) or in addition to mixture of Zn and Fe. The interaction between the studied factors had significant effect on plant height and grain yield in both seasons as well as on grain protein content in the second season, where the highest values of these parameters were recorded by application of 100kg N/fed., Zn and Fe in mixture.

The aim of the study is to isolate from collection samples of winter triticale the sources of short-stemming and high grain yield for their further involvement in the selection process in the forest-steppe conditions of middle Volga region. The studies were carried out in 2013–2017 on typical gray forest soils. 93 samples of winter triticale of Russian selection, obtained from the collection of All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov. Standard is Bashkir short-stemmed. Weather conditions during the years of study varied significantly. The studied gene pool has a wide genetic diversity in plant height (65 ... 136 cm) and yield (277 ... 579 g/m2). According to the results of analysis of variance, a significant influence of the genotype and year conditions on the manifestation of these characters was established. Plant height and yield depended on both factors and their interaction, but the first trait is determined mainly by the heredity of the varieties (46.1%), and the second - by the growing conditions (61.8%). There was a significant variation in the values of the studied indicators, both by genotypes and by years: the coefficient of intervarietal variation in the average values of the traits of grain yield and plant height for 2013–2017 amounted to 15.0 and 17.2%, respectively, with variation by years 15 , 4 ... 30.7% and 15.1 ... 20.1%, respectively. According to the results of regression analysis, it was found that within the studied gene pool the highest grain yield was formed by samples with a plant height of 86 ... 105 cm. 13 sources of short-stemming with a plant height below 80 cm and 17 high-yielding samples with a yield of 515 ... 579 g/m2 were identified. In these genotypes, the yield excess over Bashkirskaya short-stemmed standard was significant and amounted to 33 ... 97 g/ m2, or 6.8 ... 20.1%. The varieties Tribun, Skif, Kentavr, Sotnik are characterized by the highest breeding value

Winter Wheat Varieties

Penza region is characterized by a diversity of natural and climatic zones and considerable variability of meteorological factors over the years. Therefore, the creation of high-yielding winter soft wheat varieties with high protein content in grain is one of the most significant challenges in this crop breeding. The purposes of this research are twofold: assess the ability of winter wheat varieties to form high-protein grain in various environmental conditions and isolate a valuable source material for breeding. The research objective is to evaluate winter wheat varieties by such indicator as “mass fraction of protein in grain”. The research was carried out from 2008 to 2017 in a forest-steppe zone of the Penza region. The soils of the experimental field – medium-humus medium-thick leached chernozem with the 35–40 cm depth of the plowing horizon. Ninety varieties of winter wheat from the world collection were the material for the research. The forecrop is black fallow. Square of experimental fields is 3 m2, triple replication. Seeding rate – 5.5 million germinating grains/ha. Standard – winter soft wheat variety ‘Fotinya’. Mass fraction of protein in grain in early ripening and mid-early varieties of winter wheat significantly differed from those of the mid-maturing group. Winter wheat varieties from the mid-ripening group were distinguished by a high protein content (on average 15.5 %), high yield (on average 3.8 t/ha), high yield of protein per hectare (on average 0.59 t/ha). According to the level of stress resistance, varieties ‘Fotinya’ and ‘Moskovskaya 39’ stood out (0.7 and 0.6, respectively). The following varieties are characterized by high genetic flexibility (15.3–16.2): ‘Fotinya’ (Penza region), ‘Moskovskaya 39’ (Moscow region), ‘Bezenchukskaya 380’ (Samara region), ‘Badulinka’ (Volgograd region), ‘Ershovskaya 25’ (Saratov region), ‘Zimorodok’, ‘Pobeda 50’ (Krasnodar Territory), ‘Zernogradka 8’, ‘Konkurent’ (Rostov Region). All the aforementioned varieties have less variability of a characteristic over the years (coefficient of variation – 3.2–9.7 %) and are recommended for use as a starting material for creating new forms.

High grain protein in durum wheat [Triticum turgidum ssp. turgidum L. conv. Durum (Desf.)] is one of the main goals of breeding programs. Landraces may be very useful germplasm for achieving this goal. To examine their potential as a source of high grain protein content, 11 genotypes, including 7 landraces, were evaluated in 8 environments. Environment, genotype, and the interaction of the two (G E) significantly influenced the variation in grain yield, grain protein content, and grain protein yield. The environmental effect was the strongest, mostly due to differences in water supply. Grain yields of the modern genotypes were higher than those of landraces. Yields of the modern genotypes tended to respond more strongly to the higher yielding environments, but they varied more than the yields of landraces. With the exception of VK.85.18, the grain protein content of the high-yielding genotypes was almost as high as that of the best landraces. Moreover, grain protein content of these bred genotypes tended to respond more strongly to the higher protein environments. Differences in grain protein yield were closely related to the differences in grain yield. The results indicate that it is possible to improve grain protein content without grain yield being adversely affected. The results also indicate that potential gene sources should be compared over a number of environments before they can be used as breeding material or as crop varieties producing high grain protein yields.
