|Title:||Inheritance of in vitro plant regeneration ability in the tomato|
|Abstract:||Lycopersicon pimpinellifolium, with high plant regeneration ability, used as a pollen donor, was crossed with five recalcitrant L. esculentum genotypes. Statistical analysis was based upon frequency data of calluses that regenerated plants (R) in F-1, F-2, BC1 and on reciprocal crosses, with genotypes that did not regenerate plants (NR). F-1 hybrids showed a dominance effect; no differences were observed in reciprocal crosses. The F-2 rate was close to 9:7 (R:NR) and BC1 expressed a 1:3 (R:NR) rate. The results suggest an interaction of two dominant genes, indicating that the transfer of high plant regeneration ability from wild to commercial varieties would be relatively easy, since a qualitatively inherited dominant trait is involved.|
