Genotype by environment interaction for oil content in winter oilseed rape (Brassica napus L.) using additive main effects and multiplicative interaction model

Published on May 24, 2018 02:35 AM

The objective of this study was to assess genotype by
environment interaction for oil content in winter rapeseed
cultivars grown in West Poland by the additive main effects
and multiplicative interaction model. The study comprised
of 25 winter rapeseed genotypes (15 F1 CMS ogura hybrids,
parental lines and two European cultivars: open pollinated
Californium and F1 hybrid Hercules), evaluated at five
locations in a randomized complete block design, with four
replicates. Oil content of the tested genotypes ranged from
35.2 to 48.8%, with an average of 44.55%. AMMI analyses
revealed significant genotype by environmental interaction
with respect to oil content. The hybrid PN66×PN18 is
recommended for further inclusion in the breeding program
due to its high oil content, CMS ogura line PN66 and hybrid
PN68×PN18 are recommended because of its stability and
high oil content.
