Summary Some characteristics of in vitro culture of somatic tissues of maize were analysed by a diallel trial. Eight genetically different pure strains, chosen for their aptitudes, were used. The results show that there is considerable genetical variation for the characteristics of in vitro culture and that it should be possible to breed for aptitude to in vitro culture. The linear regression of hybrids on mid-parent reveals a significant heritability for such aptitude. Through selection we have improved plant regeneration after a long period of callus growth.
