ASSESSMENT OF PLATE LENTIL SAMPLES BY ECONOMIC AND BIOLOGICAL INDICATORS

The studies were conducted in 2021-2023 in Omsk region to evaluate samples of plate lentils of domestic and foreign selection and to identify sources of economically valuable indicators. The material for the study was 32 samples of large-seeded lentils, the standard being the mid-early Aida variety. The soil of the site is meadow-chernozem, medium-deep, low-humus, medium loamy with an environment close to neutral reaction (pH 6.5). In 2022 slightly arid climatic conditions were noted (HTC = 1.02), in 2021 and 2023 - very arid (HTC = 0.68 and HTC = 0.75, respectively). The preceding crop is spring wheat. Under conditions of significant influence (66.2…74.6 %) of weather conditions, the best samples in terms of a set of economic and biological characteristics were identified: k-2692 (Russia, Penza region), Rozovosemyannaya (Russia, Penza region), Sovereing (Canada), Shyraily (Kazakhstan), Anfiya (Russia, Penza region), Glamis (Canada), Penzenskaya 14 (Russia, Penza region), k-2980 (Russia, Leningrad region). The distinguished samples were distinguished by the shortest, in comparison with the standard, duration of the vegetation period by 5…9 days. They also produced, compared to the standard, a significantly higher (p≤0.05) number of beans per plant (by 9...16 pcs.), seed weight per plant (by 203.8...228.8 %), and 1000-seed weight (by 11.31…13.14 g). In addition, they demonstrated a significant superiority over the standard in protein content – 1.60...1.82 %, fat – 0.35...0.37 %, ash – 0.59...0.66 %, fiber – 0.25...0.3 %, and NEV – 0.89...0.98 %. The bean length was at the standard level (17 mm), the average seed diameter was 7 mm, the peel color was predominantly green, and the seeds cooked well (40…60 minutes). It is advisable to use these samples in the region as sources of valuable traits for breeding high-yielding varieties of lentils.
