Abstract

The efficiency of a one-generation application of honeycomb selection was studied in comparison with a one-generation application of other procedures for mass selection. These alternatives included random selection, truncation selection, grid selection and selection with independent culling levels. The result of honeycomb selection, which was continued during 3 successive generations was also established. The aim of the selection was a decreased culmlength while maintaining or improving grain yield.
The obtained results showed that it was possible to promote such a recombinant plant type by honeycomb selection, but the efficiency of this new method was somewhat disappointing. The cause for this is environmental diversity occurring within groups of 7 plants.
For better results of mass selection it was suggested to base the selection on different plant characteristics (harvest index or grain yield per ear) or to modify grid selection in such a way that per grid a variable number of plants is selected.
