- Abstract
The purpose of this study was to aβeβ the variability among clones F2 geration of papaya 'Tainung 01' on the in vitro rooting. The clones were obtained by the multiplication of explants from the F2 geration plants obtained in a greenhouse, keeping the identification during three subcultures. The percentage of rooting and shoot growth were evaluated from branches of 10 clones of papaya Tainung 01' in rooting medium containing salts and vitamins of MS medium, plus 0.2 mg L-1 IBA. The experimental design was completely randomized, with three replications and 10 branches per repetition in individual test tubes of 25 mm x 150 mm. From the results it appears that it is poβible to select clones more responsive to in vitro rooting 'Tainung 01' from the segregating F2 generation. The selection of clones more responsive to establishment of trade protocols depends on the field evaluation, due to segregation for yield traits obtained in the F2 generation.
