“…The sufficient amount of N plays an important role not only for the creation of yield and CP, but also for the increase of soluble fiber -BGLcontent in N/O grains. It is indicated in the results of different published researches (Danyte, 2013, Zute et al, 2010. Nevertheless, in this experiment one can see that the BGL content was even more significantly affected by the meteorological conditions during the respective year.…”

SUMMARYResearch and development related to the naked oat is now becoming more wide-spread as the opportunity for its different uses is understood also in Latvia. It has been recognized as a more valuable product in the food industry because both the interest of consumers in their health and the promotion of food products are increasing. Naked oat kernels contain high levels of β-glucans and unsaturated fatty acids. The aim of the study was to evaluate the yield and oat grain quality of naked oat breeding lines from Latvian oat breeding program. The following parameters were assessed -grain yield, 1000 grain weight, test weight, crude protein fat and β-glucan. The research assessed the variability of these parameters in organic and conventional farming system (at three different mineral fertilizer rates: N80, N120, N160). The field experiments were carried out at the State Stende Cereal Breeding Institute during three years (2011)(2012)(2013). Results showed that the higher N fertilizer rate positively affects the amount of the crude protein and β-glucan in naked oat grains. The farming system (η 2 =42.9 %) and testing year/meteorological condition of years (η 2 =35.9 %) had a greater impact on naked oat yield. Comparing only N80, N120 and N160 variants in conventional system it was observed that during the three year period the meteorological conditions had the greatest impact on the yield of naked oat (η 2 =86.6 %). Naked oat line 'S-156' gave the highest grain yield in conventional and organic farming systems and formed significantly higher crude protein, fat and β-glucan amounts in the grain.

Here we focused on Polish oat landraces developed in the moderate temperature zone attempting to understand their genetic and phenotypic variability in context of the pressure of environmental constrains at the locations where they had evolved. Besides molecular markers and diverse phenotypic traits the Fourier transform infrared (FTIR) spectroscopy, enabling throughput metabolic fingerprinting, was used for the description of the germplasm collection. We used sophisticated multivariable analysis to integrate the data for structure analysis and to establish mutual relationships. We found that the accessions diversity across the eco-geographical variables was manifested differently depending on selected phenotypic, genetic, and metabolic criteria.Grain metabolic fingerprint derived from FTIR spectroscopy revealed the highest degree of germplasm diversity among all of the examined traits, particularly for spectral bands assigned to lipids. The landraces, which were collected in close geographical proximity, showed clear morphological and metabolic resemblances, although they represented quite different genetic backgrounds. All three levels of analysis showed the presence of selection resulting from environmental pressures and more specifically from the temperature at the landrace origin site. This research also proved that coupling of genetic polymorphism with the FTIR fingerprinting markedly extended the description of the oat landraces diversity.
