Summary The variation in response of 23 cultivars to temperature and sucrose level was investigated for in vitro shoot cultures of potato. It was found that both temperature and sucrose level had a significant effect but in terms of the interactions with cultivars that temperature was the more important. The means and components of variation for the different treatments were examined to reveal the potential for selecting a treatment combination giving optimal expression of the characters measured to assess growth of the micropropagated plantlets. In the case of rapid multiplication systems, a high mean response for number of usable nodes combined with a low cultivar component of variation (i.e. a high response uniformly over cultivars) would be desirable. This combination of character expressions was generally achieved, in the present study, when cultures were raised at 20°C with 3% sucrose in the medium.
