Identifying Photoperiodically Neutral Genotypes or Closely Relat ed Ones to Them as the Sources of Adaptivity AmongCollection Samples of Spring Barley

摘要

The investigation of the barley collection in the different photoperiodical conditions has shownrnthat it includes the accessions, which considerably vary in the character of variation of the vegetativernperiod as well as the productivity of plants depending on the day length. It stipulates a possibility forrnidentifying some highly productive genotypes with low photoperiodical sensitivity, which is of great
