Fig. 3. Conversion of AJ09b into PCR-based STS marker and its cosegregation with BPH resistance. R-resistant parent; S-susceptible parent; 1-20 resistant progenies and 21 to 38 susceptible progenies. PCR amplification of STS primer generated 200-bp fragment in resistant parent and resistant individuals and 179-bp fragment in susceptible parent and susceptible individuals.
