Abstract
According to the field expeditions, in the conditions of stationary and cameral laboratory investigations the genofund of apricot cultivated in Nakhchivan Autonomous Republic is defined. The biological features and pomological parameters are specified and the comparative analysis is carried out. As a result of the analysis, it became clear that among the apricot cultivars grown on the territory of the Nakhchivan Autonomous Republic, 42.9% are of local origin, 11.9% are introduced cultivars and 45.2% are forms. The distribution area of cultivars are determined and it is noted that Abutalibi, Haqverdi, Girmiziyanag, Aghchanabhat, Agh novreste, Khosropshahi, Teberze, Balyarim, Shalakh cultivars have much productivity importance and they widely cultivated in the region. During the conducted expeditions, it was revealed that apricot is mainly grown in the Ordubad district of the Autonomous Republic. It was defined that 30.5% of cultivars are early ripening, 47.8% of them are midseason ripening, 21.7% of them are late ripening; but 31.6% of forms are early, 42.1% of them are middle, 26.3% of them are late ripening. The research revealed that Nakhchivan novresti cultivar and Kotam-2, Dasta-4 forms are the most early ripening in comparison with other cultivars and forms. During the learning of the phase it was proved that the blossom period is depend on climate factors and ripening period is depending on genotype features. Weight the cultivars and forms is about 32.0-58.4 g and the pulp is between 90.0-95.8%. As a result of biological and zoological studies, 41.9% of cultivars and forms were distinguished by high values of these indicators. During the dequstation Nakhchivan novresti, Shalakh, Abutalibi, Balyarim, Agh erik, Goyjenabad, Girmizi partizan sorts and Jugha-5, Dasta-4, Dasta-9, Ordubad-12, Sharur-5 forms are rated with the highest scores.
