Characteristics of introduced lentil varieties (Lens culinaris Medik.) in the Southern Forest Steppe zone of Ukraine

Abstract

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.

Chickpea Genotype Selection Based on Economically Valuable Traits to Develop High-Yielding Types

“…According to Kholod et al (2013), based on the trait "height of attachment of the lower pods," the chickpea genotypes classification were as follows: low (<15 cm) in which the placement of pods was above the ground level in 10 samples naturally, scored 9.8% of the total. However, 72 genotypes have an average height of 16-20 cm of the lower pods above the soil level, and their percentage was 70.6%.…”

Оцінка Біологічних Властивостей, Продуктивності Та Врожайності Сочевиці

“…Урожайність сочевиці залежить від продуктивності її рослин, яка, зі свого боку, зумовлює взаємодію низки показників структури врожаю. Одним із таких елементів є маса 1000 насінин, яка значною мірою визначає продуктивність сорту, а також є важливим компонентом, що характеризує продовольчі переваги сорту [24].…”
