The experimental work was carried out during the period 2014-2017 on the second experimental
field of the Institute of Forage Crops, Pleven. The object of the study is two
alfalfa progeny from open pollination (№ 30) and inbreeding (№ 3AS3) with initial forms
differing mainly in productivity (high/low) of forage and recovery (fast/slow) after harvesting.
The purpose of the study is a comparative characteristic of alfalfa progenies by
quantitative traits with a view to breeding. The results of a total of 16 cuts, harvested in the
beginning of flowering are analyzed. It was found that both progenies confirmed the characteristics
of the initial forms in terms of traits - number of stems and regrowth rate after
harvesting. Analysis of the data shows that in the open pollinating of alfalfa, the maternal
effect on forage yield is not as pronounced as the regrowth rate after cutting. In the forcedly
self-pollination of alfalfa, combined with a selection, an improvement in yield in the next
generation is observed.
