Biometric Indicators of Variety Samples of Porey Onions

The article presents the results of a study of the biometric indicators of leek variety samples and their significance for evaluating valuable morphological and economically important traits. The study was conducted during 2022–2024 using established methodological guidelines for ecological and variety testing of vegetable crops, with statistical analysis performed using analysis of variance. The biometric characteristics assessed included the number of leaves per plant, leaf length and width, leaf area per leaf, total leaf area per plant and per unit of field area, plant height, and pseudostem length and diameter. The results demonstrated considerable variation among the studied variety samples. The highest number of leaves, 13 per plant, was recorded in BIN 20, UGH 223, and K-104. The largest individual leaf areas were observed in Bandit (394.7 cm²), UGH 223 (371.6 cm²), BIN 20 (360.2 cm²), and K-104 (351.5 cm²), while UGH 223, Bandit, BIN 20, and K-104 also demonstrated the highest total leaf area per plant and per unit of field area. Significant differences were also identified in plant height and pseudostem characteristics, with BIN 20 showing the greatest plant height (101.8 cm), while BIN 20, UGH 223, and K-104 had the longest pseudostems. The findings indicate that the studied variety samples possess distinct combinations of biometric traits, reflecting differences in their vegetative growth and morphological development. In particular, the greater leaf area and pseudostem dimensions observed in several samples indicate their potential value for further breeding and variety evaluation. Overall, the obtained results provide useful comparative information for identifying promising leek genotypes and selecting plant materials with desirable biometric characteristics for future breeding and production studies.
