✦ Synopsis

A~tract. The influence of temperature stress pre-treatment on anther culture response has been examined in eight commercially desirable barley cultivars. Spikes were pre-treated in darkness at 4Β°C for periods of 0, 7, 14, 21 and 28 days. Overall, the optimum pre-treatment period was 21 days, although there were large genotype by pre-treatment interactions. The most responsive cultivar was Igri, with a mean of 38% anthers responding, and relatively little effect of pre-treatment. The greatest effect of pre-treatment was in cv. Heriot, which had 3% response with no pre-treatment and 52% response from 14 days pre-treatment.

In addition to physical and chemical factors, genotype appears to be a very important factor influencing success in anther culture. Recombination by making crosses with selected responding clones has been introduced as a possible helpful method to positively influence the success and response type v
