Diversity of the apricot gene pool in the Nakhchivan Autonomous Republic

Abstract

In the course of research work carried out by field expeditions in stationary and cameral-laboratory conditions the gene pool of the apricot cultivated in Nakhchivan Autonomous Republic (Nakhchivan AR) was defined, the biological features and pomological indicators were explored and comparative analysis was held.

As a result it was specified that among the varieties of apricot cultivated in Nakhchivan AR 42.9 % are local varieties, 11.9 % are introduced varieties and 45.2 % are introduced forms. Also the distribution area of varieties is determined, among which Abutalibi, Haqverdi, Ghirmiziyanaq, Aghchanabad, Agh novresti, Hosrovshakhi, Teberze, Balyarim, Shalakh varieties are the most economically important. According to ripening period 30.5 % of varieties are early ripen, 47.8 % are mid-season, 21.7 % are late ripen; and among forms 31.6 % are early ripen, 42.1 % are mid-season and 26.3 % are late ripen. By research it is detected that Nakhchivan novresti varieties, Kotam-2, Dasta-4 forms in comparison with other varieties and forms are the most early ripen. While phase tracing, the dependence of blossom period on climatic conditions and ripening period on genotypic characteristics was detected. It is noted that the fruit weight of the investigated varieties and forms is about 32.0–58.4 gm and the proportion of pulp is between 90.0–95.8 %.

The highest degustation assesment was given to Nakhchivan novresti, Shalakh, Abutalibi, Balyarim, Agh erik, Goyjenabat, Red partisan varieties and Dasta-4, Dasta-9, Jugha-5,Ordubad-12, Sharur-5 forms.
