Using methods shown in Kadlec et al. (1994 a, b) and Letal and Kadlec (1995), the following results have been achieved concerning the enzymatic markers of soybean: Test of association between marker loci Pb/pb (sharp/blunt trichome terminations) andgroup of QTLs (Table. 1) was significant (P < 0.05) only for number of leaves. Test of linkage disequilibrium between QTLs and loci Ep/ep (high/low activity of peroxidase seed coat) - see Table. 2 - was not significant (P < 0.05). It means that within the scope of sample lines the difference between the group with dominant allele and the group of horrtozygous lines with recessive allele is not statistically significant for any of quantitative traits observed. Only for a flowering period the significant level P=0.1 seems to prove significance in the case of a higher number of treatments.
