ABSTRACT

Rye collection regeneration and multiplication requires isolation of each plot during flowering to avoid cross-pollination. The main aim of these studies is to define the conditions for propagation of rye in a field collection. Experiments on the influence of different methods of sowing and methods of isolation of field plots on the phenology and yield structure were carried out over six years in two locations. Triangular isolators are used, protecting single rye varieties during flowering against cross-pollination by another variety. The density of 20.0 × 5.0 cm is used in regeneration of samples when only a small number of seeds is available. Weather conditions were a great influence on yield components during the vegetative period, resulting in a need for several years of comparisons of numerous taxons from the rye collection in order to obtain certain results characterising these materials.
