Maize Grain

The basis of a complex and long process of creating new maize hybrids is the selection of parent components that can serve as sources of improved biochemical and economically valuable traits. Thus, depending on the peculiarities of the directions of maize grain processing, the production requires hybrids with a high starch content, and in the starch itself – amylose or amylopectin. When used for fodder purposes, high protein content is a must. This distribution of hybrids by areas of use will increase the profitability of production and reduce the cost of final products. The article presents the evaluation results of self-pollinating maize lines collection, which has 38 samples. The collection includes selection samples of the National University of Life and Environmental Sciences of Ukraine, Institute of Plant Breeding. V.Ya. Yuriev NAAS and lines of Canadian and Russian origin which are obtained from the National Center for Plant Genetic Resources of Ukraine.

The results of studies of the quality of food and non-food grain of wheat from the southern regions of Ukraine in 2016 harvest are presented. The indicators of the quality of wheat grain were determined, the uniformity of their distribution in different classes of wheat was assessed, the content of protein fractions of the gluten complex and the molecular weights of individual protein structures were determined. It was found that the studied 13 samples of wheat grain had the following quality indicators: moisture content 9.4 ... 13.5%, bulk density 731 ... 814 g/l, protein content 10.1 ... 13.2%, gluten content 16.4 ... 25.6%, gluten quality 50 ... 110 units of the IDK device, falling number 311 ... 493 s, grain admixture 1.2 ... 10.5%, grains damaged by a wheat bug, 0.1 ... 10.1%. It was noted that the bulk density of all samples of wheat of 2 ... 6 classes exceeded the standard values in each class. In terms of protein content, 2 from 3 samples of class 5 wheat and 1 from 2 samples of 6 class exceeded the standard value of class 3 wheat (≥11.0%). The same was observed for these samples and for the gluten content (≥18%). Almost all grain samples, except for 2 samples of the 5th class and 2 samples of the 6th class, met the requirements of wheat of the 2nd class (45 ... 100 units device VDK). The falling number of all samples was high and significantly exceeded the normalized value (180 s), even for class 2 wheat. It was found that the uniformity of the distribution of individual quality indicators in different classes of wheat grain by the coefficient of variation is not the same. Such indicators of grain quality as moisture content, bulk density and protein content in different samples of the south of Ukraine in 2016 harvest fluctuated weakly (V≤10%), in terms of the amount of gluten and the falling number fluctuations were average (10% ≤V≤20%). Fluctuations in the content of grain impurities and grains damaged by the wheat bug are big (V≥20%). For the last indicator, fluctuations relative to the average are very large and exceed 120 %. This indicates that in different areas where wheat was grown, the infestation by the wheat bug was very different. It was shown that regardless of the total amount of protein determined by the Infratec FOSS express analyzer, four protein fractions of the gluten complex (albumins, globulins, gliadins and glutenins) are present in all grain classes, and the molecular weights of the protein structures of the main fractions are within small limits, which are in kDa - for albumins and globulins 20...30, gliadins 27.. 100 and glutenins 30...35. It was noted that in the varietal wheat "Chernobrova" albumins and globulins have a slightly higher molecular weight (30...40 kDa) than in non-varietal wheat.

A study was conducted to know the influence of physical and biochemical parameters on development of the pulse bruchid in green gram at RARS, Lam during 2017-18. The physical parameters of seed viz., colour, shape, surface texture, seed length and width, seed coat hardness and 100 seed weight and biochemical parameters such as protein content, phenol content and total sugars were evaluated for twelve genotypes of greengram. The greengram genotypes with smooth texture, oblong or globose shape and light coloured seed might be less preferred by the pulse bruchid for egg laying. The data showed that genotypes having low sugar and protein contents and high phenol content were resistant to pulse bruchid. The correlation studies showed that biological parameters i.e., number of eggs, adult emergence and growth index had significant positive association with protein content, sugar content, moisture content and electrical conductivity and negative correlation phenol content, 100 seed weight and seed coat hardness. In contrast, mean development period had negative association with protein content, sugar content, electrical conductivity and moisture content and positive correlation with phenol content, 100 seed weight and seed coat hardness. Multiple linear regression studies revealed that all the physical and biochemical properties of seed together were contributing to a large and significant variation (65 to 87 %) in growth parameters of pulse bruchid.
