Stability of spike weight and grain weight per spike of different wheat genotypes
Апстракт
In this paper, the stability of ten divergent wheat varieties was investigated, where two traits were
analyzed: spike weight and grain weight per spike. The trial was conducted on the experimental
field of the Center for Small Grains in Kragujevac during three growing seasons. The expressions
of the analyzed traits were statistically significant and showed additive and non-additive sources
of variation. The AMMI analysis showed significant effect of the genotype x environment
interaction, where two main components were significant (PCA1 and PCA2). The first principal
component (PCA1) expressed the largest share of the genotype x environment interaction. The
genotypes reacted differently to different environmental conditions. Genotype Szegedi 765 had
the highest value of analyzed traits, but moderate to low stability. Genotypes Sterna and Gruza
expressed the highest stability, while genotype Mironovskaya 808 showed the highest instability
in terms of both traits. The investiga...ted genotypes had the highest stability in the second year of
investigation, and the lowest stability in the first year. In terms of stability, these genotypes can
be used in wheat breeding programs.
