EFFECTS OF EXOGENOUS DNA ACTION IN TOMATO .2. GENETIC-VARIABILITY

The increase in genetic variability in an interspecific tomato hybrid of Lycopersicon esculentum and Solanum pennellii in response to the ac tion of exogenous DNA is considered. Hybrid F-1 genotypes with tomatoe s of contrasting colors and weights were obtained. Segregation into bu sh shape and size, sterility, ovary formation, and color and weight wa s obtained in the self-fertilized F-2 populations studied. Along with the usual recombinant forms, new transgressive and unusual mutant form s, which are not typical for either parent, were identified in the hyb rid progeny obtained.
