Abstract

Some characteristics of self-polinated progenies of leaf-callus regenerants of tomato were examined to select marketable strains of higher qualities. These progenies were selected on the basis of scores given to each plant for several characteristics and the growth appearance index. As a result, 14 plants were selected out. These selected plants showed i) shorter periods for raising seedlings, ii) more constant flowering and higher fruit set rates, iii) higher Brix of fruits, and iv) better well-branched growth appearance than control plants from which regenerants were originally derived. These results suggest that callus-derived regenerants could be used for the improvement of tomato cultivars.
