Abstract
The economic value of a certain genotype (hybrid or variety) is not only his
productivity, resistance to diseases, drought, lodging, etc., but the ability to maintain
positive properties in different environmental conditions of production. In nature there
is a strong interaction between genotype and environment, which every breeder tries to evaluate after the creation of new genotypes. In 2008, in the field of Agricultural
Institute Osijek were made 24 new sunflower hybrid combinations by crossing three
cytoplasmic male sterile lines and eight restorer lines. During 2009 and 2010, field trials
were set up at locations: Beli Manastir (BM09 and BM10), Osijek (Os09 and Os10),
Nova Gradiška (NG09 and NG10), and in 2010 the field trial was set up in Vukovar
(Vu10). On the data of grain yield, oil content and oil yield, for both years and all
locations (7 environments), is performed analysis of variance (ANOVA) and Additive
Main effects and Multiplicative Interactions (AMMI) analysis by the statistical program
SAS for Windows 9.1. Also, for analyzed traits are made AMMI1 and AMMI2 biplots
by the program IRRISTAT for Windows 5.0. Grain yield, oil content and oil yield were
significantly different at the tested locations and years. On average, for all investigated
hybrids in seven environments, grain yield was 3.300 t/ha, oil content 47.48 % and oil
yield 1.423 t/ha. Significantly the highest grain and oil yield was achieved in an
environment Os09 (4.220 and 1.831 t/ha) and oil content in NG10 (50.59 %). The
highest grain yield, in seven environments, had a hybrid OS-H-4 (3.913 t/ha). This
hybrid had also the highest oil yield (1.721 t/ha). The highest oil content in sunflower
grain had a hybrid OS-H-1 (50.58 %). By AMMI analysis of grain yield, oil content and
oil yield, the first two IPCA components were significant at the 0.01 or 0.05, and
explained 58.5, 73.7 and 60.5% of the total genotype x environment interaction. AMMI1 and AMMI2 biplots showed that the hybrid with the largest grain and oil yield
(OS-H-4), showed small interaction with the environment, and had a great stability, and
hybrid that had the highest oil content (OS-H-1) had a great interaction with the
environment, and small stability. In addition, hybrid OS-H-12, 15 and OS-H 19 have
displayed a good stability for grain yield, OS-H-4, 7 and OS-H 18 for oil content, and
OS-H-1, OS-H 9 and O S-H 18 for oil yield. These hybrids had all three tested traits
significantly better than the average of 7 environments.
