Abstract
The article presents the results of assessing the self-fertility of apricot cultivars and forms in the mountainous conditions of Dagestan. It is shown that most of the samples of Dagestan origin (71%) are selfsterile and semi-sterile. There was a tendency towards an increase in the number of stamens and a flower index and a decrease in the length of the pistil from self-fertile to self-fertile cultivars. Flower index in self-fertile varieties averaged 1.39, semi-sterile – 1.67 and self-sterile – 1.88. An analysis of the correlation between the number of stamens and the length of the pistil showed a positive significant relationship for self-fertile cultivars (r = 0.50***), and unreliable for self-sterile and semi-sterile ones. Based on the results of a one-way analysis of variance, significant differences were established between all groups in terms of the morphological characteristics of the flower. Pairwise comparison using the Tukey test showed the smallest significant differences between sterile and semi-sterile samples.
