Agro-biological diversity of Slovene ecotypes and standard varieties of cocksfoot (Dactylis glomerata L.): comparison and agronomic value

<p>Characterisation and evaluation of accessions, e.g. ecotypes of cultivated plants, are the primary task of each agricultural gene bank. In a field experiment, agro-biological diversity and agronomic value of 15 Slovene ecotypes (group 1) and 7 standard varieties (group 2) of cocksfoot (<...
