In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...

abstract evaluation of pomological characteristics can be useful in selection of best cultivars for commercial purposes. during this project, seven cultivars of sweet cherry including five cultivars from hungary (‘stella’, ‘sunburst’, ‘germesdorf’, ‘summit’ and ‘subima’) and two control cultivars (‘cillage blamarka’ and ‘siahmashad’) were studied by completely rondomized blocks design with thre...

selection tolerant cultivars of wheat (as a strategic plant) under drought stress by using traits that are less affected by the environment, increases efficiencies. In this regard, in order to study some genetic parameters of physiological and agronomical traits and also genetic diversity in spring wheat cultivars under normal irrigation (control) and drought stress conditions in booting stage,...

Knowledge of the vegetative and reproductive characteristics of soybean cultivars with different growth habits and maturity groups is essential for the selection of a suitable variety as well as for providing optimum conditions for their growth. In 1994 in a field located in Kholenjan of Isfahan, Iran, nine indeterminate type cultivars belonging to different maturity groups, namely Williams, Wo...

Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...

it is important to identify the genetic diversity and phylogenic relationships for achieving desirable citrus cultivars. in present investigation rapd markers were used to determine genetic diversity among 29 citrus genotypes. from 19 used primers, 248 polymorphic bands were amplified. primers opa-07 and opa-05 (with 19 and 8 amplified bands), produced maximum and minimum polymorphic bands, res...

Crop seeds are important sources of protein, oil, and carbohydrates for food, animal feeds, and industrial products. Recently, much attention has been paid to quality and functional properties of crop seeds. However, seed traits possess some distinct genetic characteristics in comparison with plant traits, which increase the difficulty of genetically improving these traits. In this study, diall...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...
