Cover area, number of spikes, length of the longest spike, plant length were examined in Lavandin (Lavandula hybrida) and Lavender (Lavandula officinalis) genotypes based on collected data from 100 individual plants belong to ten clones of each species at middle of growth period of 2010. Variation, including broad sense heritability, and correlations among characters were estimated.
Lavandula officinalis showed higher performances than L.hybrida for the characters. For instance averages of cover area and number of spikes were 67.1 cm2/plant and 6.5 cm2 in Lavandula officinalis, respectively, respectively. Theywere 56.8 and 5.7 in L.hybrida. Differenceswere found for studied characters among and within clones in the species, and also between species. The differences were higher in Lavandula hybrida than L.officinalis based on results of analysis variance. Variation among plants within clone was higher than among clones in both species except of number of spikes in Lavandula officinalis. The heritability was generally below 0.5 except of number of spikes in Lavandula officinalis (0.522). It showed non-genetic factors seem often more important for the variation in performance of plants than their genetic constitution. There were significant correlations with studied characters in Lavandula officinalis and with most of the studied characters in L.hybrida.
