IDENTIFIED RESILIENT FLAX GENOTYPES WITH IMPROVED AGRONOMIC CHARACTERISTICS FOR PRE-BREEDING

Genetic diversity evaluation in a breeding program is essential produce robust, resilient crop varieties with improved agronomic characteristics under environmental challenges the sustainable agro-ecosystems. Knowledge and full potential on impact of genotypes growing conditions flax yield traits still incomplete. The aim this study was to evaluated influence hydrothermal development important flax, analysed identified perspective for pre-breeding. Field investigations were carried out from 2014 2017 agronomically flax. In population Latvian origin 24 fibre ‘Vega 2’ (ST) as standard variety Lithuanian meteorological conditions. Correlation between years coefficients during growth period analysed. According results obtained that most significant higher plants stem yield, total plant height, technical number seed vessels per measured seasons high humidity. However, 1000 weight driest year. correlation content, seed-vessel, oil content humidity level differed dependence genotype. coefficient variability when compared yield. ‘S13/5-7/5-93’ exhibited more stable, highest (840.0 g m-2) (162.2 m-2). 80% samples short 20% medium vegetation period.
