This research was conducted within the period 2011-2013 in the Department of Plant-growing experimental facility at the Agricultural University of Plovdiv (Bulgaria). The method of fractional plots in three repetitions over an area of 10.5 m2 was used. The object of this research are eight winter oat genotypes (Avena sativa L.) - 1, 07/Z 1, Dunav 1, 08/Z 2, M-K, Kt 651, Ressor 1 and line Kt 718. The aim of the study is to establish the correlations between the studied genotype grain yield and some of its quality indicators. A genotype specificity of the correlative interconnections has been determined. For Dunav 1 and line 07/Z 1 those between yield and 1000-grain weight are medium to strongly positive. Line 08/Z2 is with small grain but high quantity of beta-glucans (4.6%). The correlative interconnections of this indicator for yield and 1000-grain weight are positive. Line Kt 718 has also got potential in terms of grain weight (1000-grain weight - 28.7 g) and beta-glucan content (3.75%). The correlation between them is positive.
