Influence of varietal characteristics and growth factors on the quality of Natsional’na and Polis’ka 90 winter wheat varieties was studded. Grain of Polis’ka 90 variety was distinguished by considerable variability of grades, however, the grain of Natsional’na variety was exposed to greater number of growth factors. Grain unit index influenced the grain quality grade of Natsional’na 90 determination, gluten quality and protein and fiber content indices influenced that of Polis’ka 90. It was established that the grain of Polis’ka variety in most of the cases had higher grades of quality than Natsional’na variety. The highest grades of quality were registered for the seed harvested after perennial grasses, namely 2d and 3d grades of Natsional’na variety and the 1t and the 2d for Polis’ka 90 variety. Greater grades of quality were registered for the seed grown according to intensive and ecological farming systems (generally, grades 1 to 3), while the lower grades were inherent to biological system (generally, grades 3 to 5).

In the production of original, basic green pea seed it is critical to to single out (select) basic plants. The marked (selected) plants shall comply with their breeder’s description. Since seed breeding events are conducted with every new variety by various persons and in various agroecologic conditions, subjective factors, as well as environmental factors, may interfere with determining parameters of every characteristic considered there. As a consequence, identification and varietal characteristics and properties are subject to change and might not correspond to the breeder’s description; this, of course, affects the quality of variety. For the purpose of leveling the above factors, example of vegetable pea serves as a suggestion of a technique for exeminig parameters of variability of quantitative traits for specific population observing the rule of «golden section».

In the article the authors show outcome of three years observation of blackcurrant varieties bred by Study Horticulture Department NULES of Ukraine for their suitabi lity to machine harvesting. Blackcurrant is the most common berry crop in Ukraine. When establishing intensive industrial plantations the varieties suitable for machine harvesting should be used. During 2006-2008 limited and unlimited traits of varieties bred by NULES of Ukraine suitability to combine harvesting were studied. All parameters of the examined varieties were compared against the requirements of the «ideal variety”. Simultaneous ripening of berries was observed in varieties Dochka Vorskly – 93,6%, Hovtva, Pamyaty Leonida Myhalevskoho – 92,6%. The pick off effort required to collect berries out of their clusters for all varieties but Yarynka was within acceptable range of 67...129 g. By effort applied for berries crush only Yarynka has failed to meet the necessary requirements. All the varie ties but Yarynka have been found suitable by growth habit of their bush (upright and semi-spread). Insufficient number fruits (6-7 pc.) in clusters for varieties Narodna and Yarynka was noted. Berries weight for all studied varieties ranged within 1.27-1.84 g, their drop-off was 3-8%, duration of harvesting period ranged from 8 to 10 days, so all the parameters of varieties suggested they were suitable for picking berries by berry harvesters. Varieties Dochka Vorskly, Universitetska, Hovtva, Pamyatna, Premiera, Narodna, Leleka and Pamyaty Leonida Myhalevskoho were selected as suitable for combine harvesting by the complex of positive parameters.

Oats technological indices have been analyzed. Influence of growing conditions on natural weight, kernel size, and hoodness is established. The study summary indicates essential dependence of natural weight and hoodness and precipitation at the stage of grain formation in coated grain oats varieties. Moisture supply in the period of grain formation essentially influenced the percentage of coated grains formation and natural weight score in naked grain varieties. Morphometric analyzes of oats caryopsis was completed using the method of machine vision. Correlation between technological indices and morphometric characteristics of naked and coated grain of oats was determined. Also, essential dependence of hoodness on 1000 seeds weight and the lack of essential correlation with morphometric characteristics of the calliopsis were established. Calliopsis width essentially influenced the weight of 1000 seeds. Metric indices of naked grain oats calliopsis exposed close correlation with kernel size and natural weight.

Purpose. Comparative studies of the photosynthetic apparatus of winter wheat varieties of modern and earlier breeding in the relation to their productivity. Methods. Field, pot experiment, biometrical, gas analysis, analytical and statistical ones. Results. It is found that the modern high-yielding winter wheat varieties have a higher rate of flag leaf photosynthesis during generative period of development, particularly at grain filling period, improved ability to store assimilates in stem and effectively use them later for grain growth. The modern varieties form crop canopy with greater leaf area and chlorophyll indexes and larger photosynthetic capacity and maintain functional activity of photosynthetic apparatus longer at the end of the growing season. Conclusions. The superiority for grain productivity of modern high-yielding wheat varieties, originated from the Institute of Plant Physiology and Genetics, NAS of Ukraine, over varieties released before the “green revolution”, results from increased capacity and durability of functioning the crop photosynthetic apparatus, higher CO2 assimilation rate and optimization of source-sink relations in whole plant.

In this study, the mitogenomes of two Paxillus species were assembled, annotated and compared. The two mitogenomes of Paxillus involutus and P. rubicundulus comprised circular DNA molecules, with the size of 39,109 bp and 41,061 bp, respectively. Evolutionary analysis revealed that the nad4L gene had undergone strong positive selection in the two Paxillus species. In addition, 10.64 and 36.50% of the repetitive sequences were detected in the mitogenomes of P. involutus and P. rubicundulus, respectively, which might transfer between mitochondrial and nuclear genomes. Large-scale gene rearrangements and frequent intron gain/loss events were detected in 61 basidiomycete species, which revealed large variations in mitochondrial organization and size in Basidiomycota. In addition, the insertion sites of the basidiomycete introns were found to have a base preference. Phylogenetic analysis of the combined mitochondrial gene set gave identical and well-supported tree topologies, indicating that mitochondrial genes were reliable molecular markers for analyzing the phylogenetic relationships of Basidiomycota. This study is the first report on the mitogenomes of Paxillus, which will promote a better understanding of their contrasted ecological strategies, molecular evolution and phylogeny of these important ectomycorrhizal fungi and related basidiomycete species.
