Abstract

Ascochyta blight is currently the most severe fungal disease of field pea (Pisum sativum L.) in Australia. Lathryus sativus (grasspea) has been found to contain the highly sought-after resistance genes for aschochyta blight, though attempts have failed at introducing useful traits from this species into field pea through conventional crossing (Pang, Brown, 1993). Protoplast isolation from field pea has been described for commercial cultivars (Lehminger-Mertens, Jacobsen, 1989; Puonti-Kaerlas, Eriksson, 1988) but never for a wild genotype. A protocol for obtaining protoplasts from L. sativus has not been published previously. This paper describes protocols for establishing a culture system fo..
