the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...
In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...
The aim of this study was to investigate the chill and heat requirements of flower buds of 8 foreign and domestic commercial cultivars and promising domestic almond genotypes during 2019 and 2020 as a factorial experiment based on a completely randomized design with 3 replications and two factors including five cultivar type (Tuono, Nanpariel, Mamaie, Shahroud 12, Rabi) and three genotypes (1-1...
Water stress is one of the most important factors limiting the growth and yield of plants in many parts of the world. In order to evaluate the effects of water stress on some morphological, physiological and antioxidant enzyme activity traits of lentil, four lentil cultivars (i.e. Gachsaran, Kimia, Ziba and Robat) in four water deficit treatments including 25%, 50%, 75% and 100% of the field ca...
for a comparison and grouping of 72 almond cultivars and genotypes, 30 traits including; 12 phenological and vegetative characters plus 18 traits related to nut and kernel were assessed, according to almond universal descriptor. the results revealed that some such traits as growth habit, flower color, nut weight, shell hardness and kernel taste carried high coefficients of variation. simple cor...
rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
Blast, caused by Magnaprthe grisea, is often an important fungal disease in the production of rice in temperate and tropical areas including Iran. To determine reaction of rice cultivars against blast disease, 40 rice genotypes from Iran and other sources from Asia were selected. Four blast isolates from different races were used to test all rice genotypes in different greenhouse tests. In bl...
This study was conducted to investigate the frost status in the 11 commercial cultivars, three newly introduced cultivars and two genotypes of olives. After the occurrence of frost at the Tarom region of Zanjan province in February 2019, three trees from each cultivar were selected. Frost symptoms were recorded based on observational indices. Gas exchange traits (stomatal conductance, transpira...

Drought stress can play an important role in limiting crop productivity and disturbing different stages of plant growth especially at seed germination in arid and semiarid regions. Breeding for drought tolerance at germination stage can enhance the number of seedlings, resulting in a higher yield of grain in rapeseed. In this research 32 cultivars of rapeseed were evaluated for drought toleranc...
