The distribution of SSR locus alleles in the samples under study was compared with that in chickpea samples from various breeding centers, including those in Ukraine. Genetic distances were calculated for the 26 ICRISAT samples and seven Ukrainian varieties. A dendrogram was constructed which grouped the samples into seven clusters; the Ukrainian chickpea varieties formed a separate cluster. <strong>Conclusions. </strong>The chickpea samples from the ICRISAT collection were found to be polymorphic at SSR loci ICCM0249, TAA170, and TAA130, with three, five, and eight alleles respectively, and monomorphic at three SSR loci: STMS11, NCPGR127, and NCPGR21. This distribution of polymorphic and monomorphic alleles corresponded to that observed in the Ukrainian chickpea varieties. Cluster analysis revealed that the Ukrainian varieties formed a distinct group, suggesting differences in genetic origin and breeding approaches compared to the ICRISAT collection.</p> N. E.

Establish the optimal age for harvesting biomass. <strong>Methods.</strong> Field, laboratory, analytical and statistical. <strong>Results.</strong> Biometric studies of eight-year-old shoots from plantations revealed differences in their height, diameter, and weight. The cultivar ‘Inger’ had the highest values: 6.42 m, 3.3 cm, and 1.76 kg, respectively. The values were slightly lower for ‘Tordis’: 6.25 m, 3.1 cm, and 1.67 kg. The heights of the other varieties ranged from 5.90 m (‘Warm-maz’) to 6.13 m (‘Wilhelm’), the diameters ranged from 1.85 cm (‘Gigantea’) to 2.55 cm (‘Marzencinski’), and the dry weights of the shoots ranged from 0.89 kg (‘Gigantea’) to 1.05 kg (‘Marzencinski’). Dry biomass productivity ranged from 9.55 t/ha (‘Gigantea’) to 36.9 t/ha (‘Inger’). A significant decrease in annual height growth was observed in all the studied cultivars: after five years in ‘Tordis’, after four years in ‘Wilhelm’, ‘Inger’, ‘Gigantea’, and ‘Marzencinski’, and after three years in ‘Warm-maz’. A significant decrease in diameter growth was observed after five years in ‘Wilhelm’, after three years in ‘Tordis’, and after four years in the rest. <strong>Conclusions.</strong> The first harvesting of biomass from the studied plantations should be carried out at the age of four years, and the subsequent harvesting at the age of three or two years.</p> Ya.
