Estimation of efficiency of selecting by the duration of winter triticale seed dormancy

Abstract

The sprouting rate and the germination index of five winter triticale varieties were studied in comparison with the forms, which were selected from them with shorter and longer seed dormancy. We identified biotypes with a higher resistance to pre-harvest sprouting of grain than the original varieties. The selection efficiency depends on the variability of the variety, as well as on the age of the seeds at the selection time. Thus, grains are best differentiated by the dormance duration in the beginning of the wax ripeness.
