“…They associated the higher values with the supply of the nutrient, especially in treatments that involved topdressing application, because of the higher leaf content of N in these treatments. Thousand-grain weight is an important parameter because higher grain yields can be achieved from the same number of embryos, only with the increase in reserves accumulated in the grain depends on up or bottom position of oat panicle (Mut et al, 2018). Uarrota et al (2017a), studied 21 white oat cultivars, with and without application of fungicide and found differences between URS Guria and URS Brava for important industrial traits, like thousand grain weight, sieve grain index and hectoliter weight.…”

The multi‐floral oat (Avena sativa L.) inflorescence influences grain size and shape distributions, affecting the physical attributes of grain quality such as plumpness, size, and uniformity. While the grain size and shape distribution has been characterized as multi‐modal, very little is known about the genetic determinants of those distributions and their properties. The goal of this study was to model grain size and shape distribution using a finite mixture distribution approach and propose new distributional traits (i.e., emerging distributional traits) to characterize genotypes. We evaluated 47 oat genotypes in four highly replicated field experiments. Grains of three panicles per plot were individually threshed and scanned. Grain area, length, width, and roundness were obtained from each grain‐based image, while emerging distributional traits were evaluated using a finite mixture distribution approach. Finally, grain size distributions from hand‐threshed panicles (representing the full biological distribution) were compared with the grain size distributions of grains harvested with a combine harvester representing commercial harvest where small grains may be blown out. The heritability of all grain traits was high (0.89–0.94), and trait distributions differed among genotypes. Grain area and length show bi‐ and trimodal distributions, while grain width and roundness are uni‐ and bimodal. Although the full biological distribution of grains differed from the combine‐harvested grains, their genetic correlations were high, suggesting the combine‐harvested distributions can be used as a proxy for full biological distributions. This study proposes a straightforward methodological approach to model grain attributes that can aid in quality evaluations for genetic studies, breeding decisions, and industry characterization.

A study was carried out at Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry. A total of 37 oat (Avena sativa L.) genotypes, which had been registered, grown or selected in Lithuania over the period 1934-2013 were analysed. Precision field trials were conducted. Conventional technology for oat cultivation was employed. The relationship between oat genotypes and year of registration, growth and selection was calculated. The greatest progress of oat genotypes registered, grown or selected in Lithuania was in the increase of yield (R = 0.73), hectolitre weight (R = 0.53), and plant height decrease (R = −0.57); the highest decrease was found in protein content (R = −0.55). The new cultivars tended to show a higher thousand grain weight, better resistance to lodging, higher starch and lower fat content, lower resistance to crown rust.
