Variability of some traits of flax seed in respect to genotype and climatic conditions

Beside its multiple use in oil producing and feed industry, flax seed is used also in pharmaceutical industry as additional medicinal component, whether as mono component or in tea mixtures. Results of a two-year cultivation of several flax genotypes are analyzed. The highest yield of seed in both study years was achieved in genotype "Z" and the lowest in standard cultivar "Mira". In regard to germination energy and total germination, the best value was determined for genotype "B" and the lowest for standard cultivar "Mira". The greatest swelling of flax seeds was established for genotype "B", and the least in the case of genotype "Z". Climatic conditions in the year of cultivation had effects on yield and quality of flax seed. During 2001. the year with high rainfall, higher yields were produced in all tested genotypes, and better germination energy, total germination and mass of 100 seeds established. In seed obtained in 2002, when average temperatures were higher, number of swollen seeds was higher U ovim istraživanjima korišćeno je seme biljne vrste lana (Linum usitatisimun L.) koje se gaji i umnožava u Institutu za proučavanje lekovitog bilja "Dr Josif Pančić", Beograd. Testirana su dva genotipa označena kao "B" i "Z" i sorta "Mira" koja je služila kao kontrola. Najveći prinos semena u obe godine istraživanja ostvario je genotip "Z" a najmanji standardna sorta "Mira". U pogledu energije klijanja i ukupnog klijanja najbolju vrednost je ispoljio genotip "B", a najlošiju standardna sorta "Mira". Najveći broj bubrenja semena lana ostvario je genotip "B", a najmanji genotip "Z". Klimatski uslovi u godini gajenja imali su uticaj na prinos i kvalitet semena lana. U toku 2001 godine, koja je imala znatno više vodenog taloga, ostvareni su veći prinosi kod svih testiranih genotipova, kao i bolja energija klijanja, ukupna klijavost i masa 100 semena. Samo je broj bubrenja bio bolji kod semena dobijenog u 2002. godini u kojoj su prosečne temperature bile više.
