Abstract
Species growing in some countries in other are very rare or even unknown. For example in Romania species like: rhubarb, fennel, asparagus, artichokes, broccoli, Brussels sprouts, sweet potatoes, black salsify, mung bean are less cultivated, but suitable for cultivation due to different reasons: yield potential, biotic and abiotic stress resistance, health benefits. The study of variability at local population 1 reveals that follows:
- low variability of leaf length - coefficient of variability (s%) = 6.5;
- low variability of leaf stem length - coefficient of variability (s%) = 9.8;
- middle variability of leaf width - coefficient of variability (s%) = 10.2.
The amount of dry mass in leaves varied between 7.25 to 16.30%, the mean value was 11, 94%.
