Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...
To identify genotypes tolerant to drought stress in rice germplasm, a factorial pot experiment was carried out in the form of a completely randomized design with three replications and 70 rice genotypes originating from Central and West Asian countries in non-stress and drought-stress conditions at the Rice Research Institute of Iran, Rasht, north of Iran, in 2019. Based on the results of this ...
the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...
lentil (lens culinaris. medik) is one of the major cool season pulse crops which could suffer damage under severe cold. some physiological parameters such as electrolyte leakage (el) have been used to assess the response of crops to cold conditions. in order to evaluate the possibility of using the el index for assessing the freezing tolerance of lentil genotypes, a factorial experiment carried...
Hepatitis B virus (HBV) genotypes E to J are understudied genotypes. Genotype is found almost exclusively in West Africa. Genotypes F and H America rare other parts of the world. The distribution genotype G not completely known. I Asia probably result from recombination events with number reported sequences for HBV small compared genotypes, which could impact phylogenetic pairwise distance anal...
Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...
Expression of related proteins and aquaporin genes in grape (Vitis vinifera L.) under salinity sress
Due to worldwide increasing of salinity, the identification of genes conferring tolerance to plants is important. The aim of this study was to investigate salinity effects on the expression of three genes-related to proteins and aquaporin in grape (Vitis vinifera L.). Based on screening study on 18 grape genotypes, H6 and Gharashani that showed lower decrease in water potential, leaf area, leaf...
Identification and selection of superior genotypes is the first step in walnut breeding programs. For identifying superior genotypes in Lorestan province, Iran, 35000 seedling genotypes were evaluated during 2008-2009. 29 Phenological traits were evaluated using IPGIRI descriptors in 288 selected seedling genotypes. Finally 54 promising genotypes with 10 major phenological traits were evaluated...
Evaluating of sunflower genotypes under different environmental conditions would be useful to identify genotypes with high stability and yield potential. In order to study yield stability of sunflower genotypes, 11 new hybrids along with four cultivars (namely Golsa, Ghasem, Shams and Farrokh) were evaluated in a randomized complete block design with four replications under four experimental fi...
To evaluate the genotype × environment interaction and determine the stable genotypes of wheat, 30 genotypes of bread wheat along with two controls namely Chamran and Chamran 2 were studied in 6 locations (Ahwaz, Darab, Dezful, Iranshahr, Khorramabad, Zabul) and two years (from 2013 to 2015), in each using an alpha lattice design with 4 replications. The results obtained from AMMI analysis dem...
