Assessment of stability of seed yield and seed oil content in confectionery hybrids using AMMI analysis

Abstract

High seed yield and low oil content are the most important criteria for the introduction of high protein confectionary hybrids into production. An important part of breeding programs is testing new hybrids and detection of hybrids distinguished by stability of tested traits under different agro-ecological conditions. To evaluate stability of NS confectionery sunflower hybrids under different environmental conditions, a trial was conducted using 10 confectionery sunflower hybrids developed at the Institute of Field and Vegetable Crops, Novi Sad. The trial was set up as a randomized block design with three repetitions, at the location of Rimski Šančevi in 2011, 2012, 2014, 2016, 2017, and 2018. The AMMI analysis was applied as one of the most important and widely used multivariational analyses for determining interaction between genotypes (hybrids) and environment (year). Comparing the environments, the highest average seed yield and seed oil content were obtained in 2011.
