Genetic variability of some agronomic traits in the Iranian Fenugreek landraces under drought stress and non-stress conditions
This study was carried out to assess the genetic diversity and heritability of various agronomic traits using twenty fenugreek landraces from Iran. The trial was conducted at Maragheh experiment station in North-west of Iran under rainfed (RF) and irrigated (IR) conditions during 2008 cropping season. Results of combined analysis of variance showed significant differences among landraces for all traits except for...

Effect of chemical properties of soils on gum elementary compositions from Acacia senegal var. kerensis in Samburu and Marsabit Districts
Geographical Positioning System was used to mark the sites of Acacia senegalvar. kerensis in Marsabit and Samburu districts. Soil and gum samples were collected for analysis of pH, carbon, nitrogen and phosphorus. Soil pH (6.0 - 6.7) varied significantly (p < 0.05) with pH of gum (4.54, 4.50, 4.51 and 4.52) in all the sites. In Merrile, organic carbon in gum (0.15%) was significantly...

Virulence of Puccinia triticina on wheat in Iran
Wheat leaf rust is controlled mainly by race-specific resistance. To be effective, breeding wheat for resistance to leaf rust requires knowledge of virulence diversity in local populations of the pathogen. Collections of Puccinia triticina were made from rust-infected wheat leaves on the territory of Khuzestan province (south-west) in Iran during 2008 - 2009. In 2009, up to 20 isolates each of the seven most...
