| Popis: | The results of the evaluation of eight breeding varieties and new varietal populations of alfalfa are presented on highly productive chernozems of the field crop rotation, sod-meadow soil of the meadow ecotope and sandy loam chernozem in the Central Chernozem region. The effective signs «Dry matter productivity» and «Seed yield» depend on the «Ecotope» factor by 68.7% and 63.58%, respectively. The assessment of seed productivity of varietal populations and morpho-anatomical features of its formation depending on the growing conditions is given. It is concluded that it is necessary to analyze the source material of variable alfalfa at the early stages of breeding in ecotopes characteristic of the region of planned cultivation. |
