Fig. 1. Polymorphic RAPD pattern obtained from random 10mers. R-resistant parent; S-susceptible parent; 1-10 resistant progenies and 11-20 susceptible progenies. Random primers AJ09, AL05, AL01 and AK10 generated 4 (a₂₆₀, b₂₃₀, c₁₈₀ & d₁₀₀), 2 (a₂₂₀ & b₄₀₀), 1 (a₂₀₀) and 4 (a₆₉₀, b₄₃₀, c₃₈₀, and d₃₄₀) polymorphic markers, respectively, for BPH resistance. The polymorphic markers are indicated by arrows.
