Assessment of stability of seed oil and protein content in confectionery hybrids using the apple AMMI analysis

Abstract

High seed protein content and low oil content are the most important criteria when introducing high protein confectionary hybrids into the production. Testing new hybrids and detection of hybrids that maintain stability of the tested traits under different agro-ecological conditions is an important part of breeding programs. In order to evaluate the stability of seed oil and protein content in NS confectionery sunflower hybrids under different environmental conditions, fifteen confectionery sunflower hybrids developed at IFVCNS were examined during 2015, 2016 and 2017, in a trial set up as a randomized block design with three repetitions at the location of Rimski Šančevi. The REML random model was used for evaluation of the effects of hybrids, years and their interaction, while the AMMI multivariational analysis was applied to determine genotype (hybrid) x environment (year) interaction. The effect of genotypes (G), environments (E), and their interaction (GE) was compared considering their contribution to the total variance. In terms of seed oil content, the effect of G (70.63 %) played a more important role than the effects of E (19.36%) and GE (10%).
