Abstract
The study concerned variability and phenotypic/genotypic correlations between the important useful traits in oat, basing on field experiments with strains and varieties. The investigation was carried out in the years 1996–2000, in 5 localities. The traits under study were following: grain yield per plot, plant height, date of heading, resistance to crown rust, resistance to powdery mildew, lodging, hull content, 1000 grain weight. The investigation confirmed a small regress in yield of new strains of oat in the years 1996–2000. On the contrary, the progress was observed in resistance to crown rust and shortening of straw, which resulted in higher resistance to lodging. The highest variability was stated for resistance to crown rust (CV = 24,9–43,2%). The , resistance to crown rust (0,77–0,89) and heading date (0,82–0,97) showed high and constant heritability in all years of the study except for 1999. A highly significant positive coefficients of phenotypic and genotypic correlation were observed between grain yield per plot and resistance to crown rust (rP = 0,66 to 0.77, rG = 0.81 to 0.98) and, on the contrary, the correlations between grain yield and % of hull were negative (rP = -0,37 to -0,42; rG = -0,80 to -0,93). Furthermore, negative correlations were found between plant height and lodging resistance hull content and date of heading. The analyses have shown that unfavourable correlations between studied traits have not been overcome yet.
