Stability and plasticity of agronomic traits in accessions of Eastern galega in the conditions of the Murmansk region
The purpose of this work was to evaluate the stability and plasticity parameters of 30 samples of the collection of Eastern galega (Galega orientalis). The research was carried out on the Polar OS VIR (Apatity, Murmansk region) in 2005-2009. Observations and records were carried out according to the...

| description | The purpose of this work was to evaluate the stability and plasticity parameters of 30 samples of the collection of Eastern galega (Galega orientalis). The research was carried out on the Polar OS VIR (Apatity, Murmansk region) in 2005-2009. Observations and records were carried out according to the VIR guidelines. Statistical data processing included the calculation of stability and environmental plasticity indices. During the years of the research, various conditions were formed for the manifestation of the studied traits: favorable – according to winter hardiness and foliage in 2005 (environment index +4.1 and +6.1), plant height and seed productivity – in 2009 (+24.8 and +10.9), bushiness – in 2006 ( +7.4), fodder productivity – in 2008 ( +0.33); unfavorable – for winter hardiness in 2008 (-2.9), height and feed productivity in 2006 ( -23.8 and -0.44), bushiness, leafiness and seed productivity in 2007 (-5.0, -3.0 and -6.4). The variability of the stability parameter in plant height and yield of air-dry mass is average, in bushiness, leafiness and seed yield is high, in winter hardiness is very high. The studied accessions are fairly evenly distributed among groups with low, optimal and high values of the stability parameter. Valuable material for breeding are k-55536 and k-55537 accessions naturalized in the Murmansk region with high feed (19.5±2.32 and 19.8±1.94 t/ha) and seed (6.45±0.371 and 6.85±0.282 c/ha) productivity, stability of the seed yield index, responsiveness to improving growing conditions according to the yield of air-dry mass. |
