Relationships Among Some Quantitative Traits and Heritablities İn Cultivated Oats (Avena sativa L.)

The objectives of this study were to examine the relationships among quantitative traits and to estimate their broad sense heritabilities in cultivated oats (Avena sativa L.). Four oat crosses were used in this experiment. Biological yield had the highest correlation with grain yield in all F2 populations, followed by harvest index. Grains per panicle appeared to be the most useful trait to use in indirect selection for grain yield among yield components in terms of heritability values and correlations with grain yield. Grain yield per plant significantly and positively associated with groat oil content in two oat populations. The broad sense heritability values of groat oil content ranged from 13 to 77%. Grain yield per piânt had heritability estimates between tow and moderate values.•
