1999

Nuts of 30 wild growing plants, selected for cultivation potentiality, and 6 whole samples were analysed in the period from (1973) 1976 till 1984. The average nut mass was 0.9-1.2 g, the limits being from 0.62 till 1.51 g (in one sample 2.05 g). In half of the samples, 91-100 per cent of nuts were heavier than 0.7 g. In the other half of the samples, the mass of 50-100 per cent of nuts was over 1g. The kernel mass was mostly 0.21-0.44 g (in one sample 0.81 g) and the kernel percentage was 26-41 per cent. Protein content, per absolute dry matter, was 15.4-26.3 per cent (the average 21.2 per cent) and fat content was 49.5-59.1 per cent (the average 53.5 per cent). The differences in nut and kernel mass, and chemical composition were insufficient between the plants due to variability between the years. This result was surprising for breeding purpose
