| Summary: | Lallemantia iberica is an annual, herbaceous and drought tolerant plant in the mint family, Lamiaceae, which is cultivated for its seeds. Diversity of 12 dragons head landraces were studied for phenotypic and genotypic variations using agro-morphological traits and some drought tolerance indices. Field study was conducted in the spring of 2013 as a randomized complete block design with three replicates in Maragheh. Results of analysis of variance showed that there was significant difference among the studied landraces for all agro-morphological traits under study between the experimental sites. Combined analysis for grain yield showed that there were significant differences between the experimental sites. The average grain yields were in the range of 730 to 1380 kg.ha-1 under complementary irrigated condition and from 360 to 680 kg.ha-1 under rainfed conditions. Kalibar and Nazarlo landraces for all parameters were highly drought tolerant. Cluster analysis grouped these populations into three distinct clusters. The results also indicated that plant height and days to flowering under complementary irrigation and main branches under rainfed conditions exhibited highest correlations with seed yields. |
