Medicago sativa, soil acidity, seed productivity, correlation coefficient, hydrothermal factorsAbstract
This study assessed the impact of hydrothermal factors on and contributions of individual seed productivity components to the seed yields of alfalfa germplasm accessions of different eco-geographical origins grown on soil with increased acidity over two years of sward utilization. A significant influence of hydrothermal factors on seed productivity was observed: minor to moderate droughts during anthesis and harvest increased it, while precipitation, conversely, decreased. It was concluded that to reduce the time spent on structural analysis, it is sufficient to use traits that are most significantly affected: number of productive shoots, racemes per shoot, pods per raceme, and seeds per pod. Further research is needed on minimizing seed losses caused by genetic, biological, and mechanical factors.
