ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...

Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...

in the present study, twenty two selected lines from eleven iranian eggplant (solanum melongena l.) landraces along with varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (karaj, varamin and dezful). sum of yield and marketing score for each line was recorded. analysis of variance for yield showed significant differences ...

striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in africa. the development of host plant resistance is one of the most practical stiga control strategies. in this study experiments on 36 maize inbred lines were conducted in pots and in field during the two rainy seasons of 2009 at kibos and alupe statio...

the theoretical and experimental investigation on the thermo-mechanical properties of carbon nanotube (cnt) as reinforcer for oil and gas pipes has increasingly become a hot research area for many engineers and material scientists in recent years. this is mainly due to the advent of the new composite material systems that exhibit exotic material and mechanical properties as compared to the trad...

The present study was designed to investigate the in-vitro morphological assessment of apoptotic effect caused by nimbolide on the selected cancer cell lines (DU-145, PC-3, A-549) and normal cell lines (NIH3T3, CCD-18Co). The cells were grown in 6 well tissue culture plates after treatment with different concentrations of nimbolide and untreated control cells. Apoptotic and necrotic ce...
