Investigation of the growing performance of promising almond genotypes obtained through selection breeding under in vitro conditions

Almond is one of the economically important nut species for Türkiye. There are many genotypes adapted to different regions of Türkiye. The propagation of these genotypes through plant tissue culture methods is essential. Among nut species, almonds are classified as recalcitrant plants that respond poorly to plant tissue culture techniques. In this study, the development of eight genotypes obtained through selection was examined under in vitro conditions in full and ½ NRM media containing different concentrations of IBA (0, 1, 2 mg/L). As a result of the study, the longest plant height was observed in genotype 48-6 (2.04 cm), while the highest number of leaves was obtained in genotype 33-B-44 (12.26 leaves). Rooting was observed in genotype 33-B-54, which was selected from Mut, Mersin, in a ½ NRM rooting medium supplemented with 2 mg/L IBA. The results are considered significant since these genotypes have been selected for the first time.
