AbstractHigh quality is the main goal of today’s maize breeding and the investigation of grain quality traits would help to breed high-quality varieties in maize. In this study, genome-wide association studies in a set of 248 diverse inbred lines were performed with 83,057 single nucleotide polymorphisms (SNPs), and five grain quality traits were investigated in diverse environments for two years. The results showed that maize inbred lines showed substantial natural variations of grain quality and these traits showed high broad-sense heritability. A total of 49 SNPs were found to be significantly associated with grain quality traits. Among these SNPs, four co-localized sites were commonly detected by multiple traits. The candidate genes which were searched for can be classified into 11 biological processes, 13 cellular components, and 6 molecular functions. Finally, we found 29 grain quality-related genes. These genes and the SNPs identified in the study would offer essential information for high-quality varieties breeding programs in maize.

The article studies the technological grain quality traits of rice varieties of Russian breeding Rapan, Flagman, Olimp, Azov, Patriot in the yield of 2017-2019 grown in the Abinsky district, Krasnodar region. Purpose of the research was to study the effect of doses of nitrogen fertilizers on the technological grain quality traits of rice varieties with a low amylose content. Rice varieties were evaluated by mass of 1000 absolutely dry grains, filminess, vitreousity, and fracture when grown with different doses of nitrogen fertilizers N60, N120. With an increase in the dose of nitrogen to N120, "the mass of 1000 absolutely dry grains", "vitreousity", "fracture" remained unchanged or the "filminess" changed. The pattern of changes in grain quality traits may indicate an intensive type of varieties Rapan and Olimp.

An increase in the doses of nitrogen fertilizers applied during the cultivation of new rice varieties Nautilus and Yakhont in the old-deltoid and valley agrolandscape zones led to significant changes in grain quality traits. The grain size of the varieties grown in the Krasnoarsmeysky district did not change due to the level of nitrogen fertilizers, for those grown in the Abinsky district, decreased by 0.3 g in variety Nautilus and increased in variety Yakhont with increased dose of applied nitrogen. The vitreousity of grain increased in Nautilus in the Krasnoarmeysky district by 2%, in Abinsky - by 7%; in the variety Yakhont - increased by 2% and practically did not change, respectively. A tendency toward a decrease in grain fracture in the Krasnoarmeysky district and an increase in head rice content in the variety Nautilus in the Krasnoarmeysky and Abinsky districts was noted.
