Abstract
Lupinus mutabilis Sweet is a cultivated species in South America. Numerous attempts to adapt the species to the conditions of temperature climate have shown that yield stability and earliness are of paramount importance. Widening genetic variability would be especially desirable in order to obtain promising selections. A mutation program was used to increase genetic variance. Seeds of populations: XM.5, 15 and cv. Potosi were radiated with caesium 137 gamma rays. From the obtained material, 25 mutant lines were chosen and evaluated in an experiment conducted at Swojec Experimental Station (of Wrocław Agricultural University) using a randomized complete block design with three replications. The plot was 1 m2. Significant differences among the lines were found for height of the main stem, no. of lateral branches of first order and no. of seeds/pod. However, coefficients of variability were relatively low, ranging from 4% to 13%. No significant differences were observed for no. of pods/plant, no. of seeds/plant, seeds yield/plant and 1000 seeds weight.
