Fig. 3. Metaphor agarose gel (BMA, Rockland, ME) showing the results of polymerase chain reaction amplifications based on the use of the sequence characterized amplified region marker converted from E-ACT/M-CAC₁₁₅. M, P_s, P_r, B_r, B_s, R, H, and S represent 20-bp ladder, susceptible parent, resistant parent, resistant bulk, susceptible bulk, and resistant, heterozygous, and susceptible individuals, respectively, from the population IT93K-693-2 x IAR1696.
