Extended Abstract Introduction and Objective: Flax (Linum usitatissimum L.) from the Linum genus and Linaceae family is one of the oldest oil products in the world. A natural population with sufficient genetic diversity is necessary to select the desired phenotypic traits, so the study of genetic diversity and the correct selection of essential tools is the main breed of plant. Agriculture fac...

Biological fertilizers are compounds comprising various free living microorganisms that are able to change the basic nutrients into available form through biological procedures. Being an important source of nutrients in sustainable agriculture, these fertilizers lead to better seed germination and development of root system. In order to investigate the effect of biological fertilizers on the me...

Flax (Linum usitatissimum L.), an oilseed crop, is widely adapted and grown in many regions of the world. Oil from regular flaxseed is used as an industrial drying oil because of the high level of linolenic acid (>50 %). However, the oils from new mutant genotypes of flax with a very low linolenic acid concentration (<2 %) are edible. Yellow seed colour can be used as a visual marker to disting...
