Localization of QTLs for in vitroplant regeneration in tomato

BMC Plant Biology

Table 2 QTLs for shoot regeneration traits (Bud percentage (B), Regeneration percentage (R) and Productivity Rate (PR)) found to be significant at the empirical genome wide mapping threshold by restricted Multiple QTL Mapping (rMQM) in BC₁ and Interval Mapping (IM) in F₂
