Özet
We examined the effects of late spring frost on grain yield (GY) and quality of spring triticale (
× Triticosecale)
genotypes, based on genotype plus genotype × environment interaction (GGE) biplot analysis. The study included a total of
25 genotypes, including 20 advanced lines, 3 triticale varieties, and 2 candidate lines. The genotypes were evaluated for GY
and quality traits during the 2012/2013 (normal season) and 2013/2014 (late spring frost) seasons. We observed significant
differences between seasons for GY and quality traits, as affected by changing environmental conditions over the two
seasons. Late spring frost caused a statis tically significant 50% reduction in GY, 7.1% reduction in test weight (TW), and
26.1% reduction in thousand grain weight (TGW); however, it positively affected protein content (PC), and it increased by
42.6%. We observed that early heading genotypes were differently affected by late spring frost, compared to late maturing
genotypes, in terms of GY, TW, and TGW. The GGE biplot analysis highlighted three and four distinct groups of traits in the
2012/2013 and 2013/2014 growing seasons, respectively. Results from the GGE biplot analysis revealed that G12 and G16
were stable and ideal genotypes for all of the traits in the 2012/2013 season, and G10 and G23 were stable and ideal for the
2013/2014 season. In addition, G10 was the best genotype averaged over the t wo growing seasons. The genotypes G9, G13,
and G17 were more stable and higher yielding, based on Additive Main Effect and Multiplicative Interaction (AMMI)
analysis, compared to the remaining genotypes.
