Abstract
In addition to morphological and pomological techniques, the molecular
analysis produces more information for diversity studies. Recently, the
iPBS marker system is one of the techniques and a new marker system
for apple studies. In this study, morphological, pomological, and
molecular characteristics of local apples were investigated in 48 different
samples from 29 different rural areas with varying altitudes between
1125-1726 m in Niğde, Turkey. Fruit size, fruit weight, the color of fruit
peel, total soluble solids content, fruit flesh firmness characteristics are
important in terms of yield, quality, storage, transportation and
attractiveness. According to the pomological results from these traits,
CKR2, DMR3, CLL, HCB2, YSL, ULG, ELM1, ICM have been found
to superior among genotypes. In order to molecular results, the similarity
of the samples varies between 0.61-1.00, under the light of this result,
molecular data differentiated all individuals used in the study except one
pair. Molecular data displayed that these differences were caused by
genotypic differences as well as environmental conditions. This study has
contributed further information about the usage of iPBS primers on apple.
To protect the plant material used in the study, a collection orchard was
established with genotypes. To conclude, the findings are expected to
shape future breeding studies.
