Genetic diversity of Phleum spp. and identification of genes involved in water stress response
Genetic material of Lithuanian origin varieties, breeding lines and wild ecotypes representing P. pratense, P. bertolonii and P. phleoides species were studied for the most important agro-morphological and feeding value indicators as well as at the genetic level employing different biochemical–molec...
