Purpose. To evaluate the introduced lentil varieties (Lens culinaris Medik.) originating from Canada and Spain in the conditions of the Southern part of the Forest-Steppe of Ukraine according to a complex of indicators of productivity and adap­tability. Methods. During 2019–2021, in the conditions of the plant research station Ustymivka Experimental Station of Plant Production of the Plant Production Institute of the NAAS of Ukraine (Poltava Region, 49o18’21”N, 33o13’56”E), 26 new samples of lentils from Canada and Spain were studied. In the pod and seed ripening stage (BBCH 86–90), under field and laboratory conditions, indicators of yield, productivity, 1000 seed weight, early-ripening, plant height and height from the soil of the first pod, number of pods and seeds per plant, number of seeds in a pod, pod parameters. Results. In the process of studying the new lentil samples, it was found that their productivity varied from 127 to 258 g/m2, with the most productive varieties being ‘CDC Creenstar’, ‘CDC Cherie’ (Canada), ‘Angela’, ‘Amaya’ (Spain). Throughout the study period, the highest productivity, according to the indicator “seed weight per plant”, was shown by the plants of the following lentil varieties: ‘CDC Cherie’ (4.4 g), ‘CDC Creenstar’ (4.2 g), ‘CDC Greenland’ (4.5 g), ‘CDC Imigreen’ (4.4 g), ‘CDC QG-2’ (4.1 g), ‘CDC Impulse’ (4.0 g) (Canada), ‘Angela’ (4.6 g) (Spain). Plant productivity was high, both in terms of increased number of seeds and 1000 seed weight. The highest level of the indicator of the number of pods per plant was recorded in the lentil varieties ‘CDC Imax’ (64.4 pcs), ‘CDC Impala’ (65.5 pcs), ‘CDC QG-2’ (67.4 pcs), ‘CDC Creenstar’ (67.8 pcs), ‘CDC Cherie’ (75.2 pcs) (Canada), ‘Amaya’ (64.8 pcs), ‘Angela’ (75.1 pcs) (Spain). Almost all the examined samples were of medium ripeness (81–85 days) and optimal for the Southern Forest Steppe Zone of Ukraine. The Canadian varieties ‘CDC QG-2’, ‘CDC SB-2’, ‘CDC Impulse’, ‘CDC Imvincible’, ‘CDC Impact’ were the earliest (76 days). Varieties combining several valuable characteristics deserve special attention: ‘CDC Creenstar’, ‘CDC Greenland’, ‘CDC Impulse’, ‘CDC Impact’ (Canada), ‘Angela’ (Spain). Conclusions. The above mentioned varieties can be recommended as sources of valuable traits for practical use in breeding, and they are also suitable for cultivation in the Southern Forest Steppe Zone of Ukraine.

Aim. To assess new introduced varieties of pea (Pisum sativum L.) of different ecological and geographical origin in conditions of the Southern part of the Forest-Steppe of Ukraine according to a set of productivity and adaptability indicators. Methods. During 2018–2020 in the conditions of Ustymivka Experimental Station of Plant Production of the Plant Production Institute named after V. Ya. Yuriev NAAS of Ukraine (Poltava region, 49°18′21″N, 33°13′56″E) 30 new pea samples originating from Belarus, Azerbaijan, Canada, Poland and the Netherlands were studied. In the ripening phase of pods and seeds (BBCH 86–90) in field and laboratory conditions yields, productivity, 1000 beans weight, early-ripening, plant height and height of attachment of the lower pods above the soil level, number of nodes to the first pod and their total number per plant, number of pods and seeds per plant, number of seeds per pod, pod parameters were studied. Results. As a result of studying new samples of pea, the range of variation of their yield from 200.5 to 300.0 g/m2 was established, while the varieties ‘Aleks’, ‘Atlant’, ‘Minskiy ovoschnoy’ (Belarus), ‘Fidan’ (Azerbaijan), ‘Dacota’ (Canada), ‘Angela’ (Netherlands) were more productive, in which the mass of grain from the plant exceeded 10.0 g. The productivity of the plant was high due to both the increased number of seeds and the weight of 1000 grains. Almost all the studied samples were mediumripe (71–80 days) and are optimal for the Southern Forest-Steppe zone of Ukraine. The most early maturing (64–69 days) were the Belarusian varieties ‘Yan’, ‘Gontso’, ‘Goryinets’, ‘Alfa’, ‘Pryivabnyi’, ‘Malyish’ and the Dutch ‘Angela’ variety. The lowest varieties were Belarusian varieties – ‘Goryinets’, ‘Vlad’, ‘Alfa’, ‘Atlant’ and others (31.0–60.0 cm), which can be used as sources on this basis. Special attention should be paid to varieties that combine several valuable features: ‘Aleks’, ‘Atlant’, ‘Minskiy ovoschnoy’, ‘Korelicheskiy ovoschnoy’, ‘Slodyich’, ‘Malyish’, ‘Kosmay’, ‘Kelvidon’ (Belarus), ‘Fidan’ (Azerbaijan), ‘Jof’ (Poland), ‘CDC Limerick’ (Canada), ‘Orix’ (Spain). Conclusions. The above varieties can be recommended as sources of valuable traits for practical use in breeding, and they are suitable for cultivation in the Southern Forest-Steppe, subject to inclusion in the State Register of plant varieties suitable for distribution in Ukraine.

Purpose. Evaluate the introduced samples of soft winter wheat from the international nursery Common Bunt-Resistant Nursery (CBUNT-RES) of different ecological and geographical origin in the southern part of the Forest-Steppe zone of Ukraine according to a set of productivity indicators in order to define the most valuable samples and describe them.Methods. During 2016–2019 on the base of Ustymivka Experimental Station for Plant Production of the V. Ya. Yuriev Plant Production Institute of NAAS the authors studied, evaluated and described 75 new soft winter wheat samples of various eco-geographical origins by productivity traits. In the field and laboratory conditions, indicators of yield and productivi­ty were determined: 1000 grains weight, plant height and ear length, the number of spikelets and grains in the ear, weight of ear and grain and early-ripening.Results. Plant material with increased parameters of economic and biological characters was identified. During studies, it was found that ‘F08347G8’, ‘F00628G34-1’ (Romania), ‘91-142A61/KATIA1//GRISET-4’, ‘SAULESKU#44/TR810200//GRISET-4’, ‘ATTILA/BABAX//PASTOR/4/…’ (IU067591) (Turkey), ‘INTENSIVNAYA//PBW343*2/TUKURU’, ‘SANZAR-8/KKTS’ (Mexico) were the high-yielding varieties. The samples of soft winter wheat as ‘F08347G8’, ‘F00628G34-1’ (Romania), ‘INTENSIVNAYA//PBW343*2/…’ (IU067637) (Mexico), ‘ATAY/GALVEZ87/6/TAST/…’ (IU067587), ‘DE9/MERCAN-2’, ‘KRASNODAR/FRTL/6…’ (IU067595), ‘SAULESKU#44/TR810200//GRISET-4’, ‘GANSU-1/3/AUSGS50AT34/…’ (IU067598), ‘ORKINOS-1*2/3/AUS…’ (IU067608), ‘KAMBARA1/ZANDER-17’ , ‘TAM200/KAUZ/4/CHAM6//…’ (IU067612) (Turkey) contained a large grain weight (more than 5.0 g), plant productivity in these samples was rather high due to increased amount of grains and the thousand kernel weight.Conclusions. The introduced soft winter wheat samples of various eco-geographical origins were adapted to the Southern Forest-Steppe and can be recommended as a source material in breeding to increasing productive capacity.
