The study of phenotypic plasticity and stability, according to which the potential of
new spring canola varieties adaptability for agroecological technology of spring canola growing
in the strategy of intensification of plant production is actual. The new canola varieties, which
were included in the State register of plant varieties suitable for dissemination in Ukraine was
studied. Field studies were carried out in 2018–2019 on the testing sites of the Ukrainian Institute
for Plant Variety Examination in Forest and Forest Steppe zones of Ukraine. The phenotypic
plasticity and stability analysis for yield, 1,000 seeds weight, protein and oil content were carried
out according to the Eberhart and Russell approach. As results of this study, it was determined
that for yield Cleopatra and SAOKER CL varieties are considered as stable. CEBRA CL and
Lavina varieties are characterized stability of 1,000 seeds weight during studied years. According
to the Wricke's ecovalence deviation and standard deviation Lavina, Lakritz and CEBRA CL
varieties consider as intensive type varieties for yield; for 1,000 seeds weight - Cleopatra and
SAOKER CL varieties. According to standard deviation for protein and oil content CEBRA CL
and SAOKER CL varieties are considered as highly adapted. Cleopatra, Lavina and Lakritz are
stable for protein content. For oil content CEBRA CL and SAOKER CL varieties are considered
as stable. For protein content CEBRA CL and SAOKER CL varieties are intensive. Thus, spring
canola varieties, which are intensive for studied characteristics, respond positively to an
improvement of growing conditions.
