Heterosis and combining ability analysis in bread wheat (Triticum aestivum L.)
Heterosis and combining ability analysis were studied in a 7 × 7 diallel set of bread wheat. Analysis of variance (ANOVA) revealed the presence of significant variance due to general combining ability (GCA) among the parents for all the traits, and due to specific combining ability (SCA) among the crosses for the all the traits except for number of tillers per plant, plant height and number of spikelets...

Evaluation of antifungal and antioxidative potential of hydrolytic products of glucosinolates from some members of Brassicaceae family
The primary aim of the present study was to evaluate antioxidative and antifungal potential of hydrolytic products of glucosinolates. These two bioactivities were assessed in the seeds of the rocket salad, Indian rape, cabbage, cauliflower, knol-knol and radish using DPPH and disc diffusion assays. Alternaria alternata was used as test pathogen in disc diffusion assay. The antioxidative and...

Biochemical and molecular characterization of submergence tolerance in rice for crop improvement
Submergence stress is considered as the third most important limitation of rice production contributing to its low productivity in lowland and rainfed ecosystem. Characterization of genotypes and using them in breeding programme is likely the best option to withstand submergence and stabilize productivity in these environments. However, progress in genotypes characterization has been slow but can...

Combing the monogenic and polygenic resistant genes to late blight in tomato
Late blight is a serious disease affecting tomato production especially in tropical and subtropical regions. Twenty-five crosses were generated from ten diverse parents to combine both the horizontal and vertical late blight resistance genes of late blight. Five inbred lines with polygenic resistance genes derived from interspecific cross Solanum lycopersicum x S....

Bioassay study of fenugreek extract’s allelopathic effects on the germination and growth of several crops and weeds
In order to study the extract effect of different parts of fenugreek (Trigonella foenum-graceum L. (on germination of several crops and weeds, an experiment was conducted with completely randomized factorial design and 3 replications, in the laboratory of Faculty of Agriculture, Ferdowsi University of Mashhad, during 2010. The following four species were included: soybean (Glysin max), sesame (Sesamus...
