Zusammenfassung: | NS soybean cultivars were assessed for variability of and correlations
between yield components and the effect of genotype - environment interaction
on yield, yield component and morphological characteristics. Experiments were
carried out at Rimski Sancevi experiment field in 2009 and 2010. The
following characteristics were evaluated: plant height (cm), height of first
pod (cm), 1000-grain weight (g), grain yield (kg/ha) and the combined content
of oil and protein in grain (%). Combined contents of oil and protein in
grain soybean were determined by a non destructive method of near infrared
spectroscopy on PERTEN DA 7000 (NIR/VIS Spectrophotometer). The studied
characteristics varied significantly depending on genotype and year. The
highest yield of 5273 kg/ha was obtained in 2009 with the genotype Victoria.
Highest 1000-grain weights, 2009-2010, were achieved with the genotypes
Valjevka and Victoria (149.27 g and 147.23 g). Maximum heights of first pod
(19.40 cm) were recorded for the genotype Victoria, 2009-2010. Highest
protein contents were obtained with the genotypes Valjevka and Victoria,
2009-2010, were and highest oil contents (21.73%) with the genotype Tea.
Protein content was positively significantly correlated with 1000-grain
weight and negatively significantly correlated with oil content, and
negatively correlated with yield and the height of first pod. Oil content was
positively correlated with the height of first pod. Thousand-grain weight was
negatively highly significantly correlated with oil content in grain and
negatively significantly correlated the height of first pod. The results of
this study should facilitate further soybean breeding for improved seed yield
and protein and oil contents.
U radu je proucavana varijabilnost i medjuzavisnost komponenti prinosa i
interakcija genotip spoljna sredina kod NS sorti soje. Istrazivanje je
izvedeno na Oglednom polju u Rimskim Sancevima tokom 2009. i 2010. godine.
Ispitivana su sledeca svojstva: visina biljaka (cm) i visina prve mahune
(cm), masa 1000 zrna (g) i prinos zrna soje (kg/ha) i sadrzaj ukupnih
proteina i ulja u zrnu (%). Sadrzaj ukupnih proteina i ulja u zrnu soje
odredjen je metodom infracrvene spektroskopije na aparatu PERTEN DA 7000,
(NIR/VIS Spektrofotometar) nedestruktivnom metodom, na principu NIR (Near
Infra Red) tehnike. Sva proucavana svojstva signifikantno su varirala u
zavisnosti od genotipa i godine. Najveci prinos 5.273 kg/ha u 2009.oj godini
dao je genotip Victoria. Najv |
