Abstract

The aim of the study was to elucidate how the genes responsible for inheritance of traits determining: grain yield per plant, number of grains per plant, grain yield per panicle, number of grains per panicle and number of panicles per plant, operate in spring oat (Avena sativa L.). It was assumed that these traits are inherited according to the additive-dominance model. To verify this hypothesis, a three-parameter Jinks-Jones model was applied. The experiment was carried out in two replications in the field of the Breeding Station Strzelce. Three varieties of oat were assayed: Góral, Sławko and STH 3096 (now var. Szakal). A biometrical analysis of the 5 traits was performed on 20 plants/variety, chosen at random (10 plants/replication). The analysis of variance showed significant variability in the traits among 6 generations as well as within the experimental combinations. To verify the additive-dominance hypothesis, chi-square test was used. Since the values measured by chi-square test appeared to be not significant, the results strongly suggest the additive-dominant character of the effects observed in oat.
