Abstract. The aim of the present study was to evaluate the effect of leptin gene polymorphism on the fattening and slaughter performance traits in the Polish Synthetic Line 990 young boars and to estimate the frequencies of LEP/HinfI alleles and genotypes.Altogether, 205 young boars of the 990 line were included in the study. Based upon the carried out live evaluation, information was obtained in respect of following traits: body weight on day 21, 28, 70 and 180 of life; average daily gain; feed efficiency; mean backfat thickness; height of m. longissimus dorsi; percent meat content; and selection index. Genotype determination was performed using the PCR-RFLP technique. The lengths of the restriction fragments for respective alleles following digestion with HinfI were: 152 bp (allele T) and 84 + 68 bp (allele C). Two genotypes were found, TT (frequency 0.8) and TC (frequency 0.2). The analysis of relationship between different LEP genotypes and all analysed traits showed small and statistically non-significant differences.
