The paper presents the agrobiological, ecological and technological evaluation of the French walnut cultivar Lara introduced in Bulgaria. The study was carried out in the period 2009– 2010 with trees in their seventh-eighth vegetation, grafted on common walnut Juglans regia L. rootstock. It was established that the cultivar was well adapted to the conditions of South Bulgaria and showed a good resistance to late spring frosts. Under the climatic conditions of the country it demonstrated a moderate susceptibility to bacteriosis X. arboricola pv. juglandis and a very good resistance to anthracnose G. leptostyla. Tree growth is moderate to vigorous with lateral fruiting. In both reporting years Lara cultivar had higher yields than the standard Sheynovo. The fruits of Lara are medium large, the mean nut weight being 12.9 g. Their shape is spherical. Kernel skin is pale coloured. The kernel percentage is 44.0 %. Fruits ripen from the end of September to the first decade of October. The oil content of the cultivar is 62.26 %.
