Abstract: Several tissue types ofLupinus albus L. were investigated as sources for the isolation of protoplasts. Cotyledons from in vitro seedlings were found to yield the highest number of protoplasts compared with leaves, hypocotyls and roots. A combination of the protoplast isolation enzymes, cellulase and Pectolyase Y23, was capable of releasing the highest number of protoplasts compared with a combination of cellulase and Macerase. Protoplast yield increased with increasing cotyledon age but was accompanied by a progressive decline in protoplast viability. The optimal combination of protoplast yield and viability occurred when the protoplasts were isolated from 14- to 18-day-old cotyledons. The ratio between the volume of enzyme solution and the tissue biomass did not affect the protoplast production significantly. This is the first report of the isolation of protoplasts from a lupin cotyledon and, following the procedure described in this paper, an average yield of 1.2 × 10[6] protoplasts per gram of fresh tissue was obtainable.
