Abstract
Introduction. The initial material is the basis of the current breeding work with all agricultural crops, including alfalfa. The purpose of the conducted work is to estimate the productivity of alfalfa samples in the collection nursery, depending on the growing conditions and the identification of the most adapted samples according to the trait “green mass productivity”.
Materials. The objects of the current study were 30 alfalfa samples (16 samples from Canada; 11 samples from the USA; 1 sample from Peru; 2 samples from France) from the collection ARIGCR named after N.I. Vavilov.
Results. The estimation of alfalfa samples for the presence of adaptive properties based on the trait ‘green mass productivity’ showed that: — the genotypes К-27116, К-43269, К-43272, К-48771, К-48775, К-48776, К-50545, К-50561, К-45119 are more responsive to changes in environmental conditions; the genotypes К-32873, К-33299, К-42684, К-42249, К-47803 are characterized with a slight bi < 1 response to changes in environmental conditions; the genotypes К-36104, К-48778, К-42694, К-45715, К-47800, К-47801, К-47802, К-43260 are characterized with high stability to stresses; the genotypes К-43272, К-50545, К-47806, К-47807 are characterized with genetic adaptability; the genotypes К-36104, К-48778, К-48715, К-47800, К-43260 are characterized with more stability of response to changes in environmental conditions; the genotypes К-36104, К-48778, К-45715, К-47800, К-47801, К-47802, К-39978, К-43260 are characterized with great homeostasis (ecological adaptability).
