low efficiency of callus induction and green-plant regeneration have limited the application of anther culture in breeding programs. this study was conducted to determine the inheritance of callus induction and plant regeneration in rice (oryza sativa) anther culture. ten genotypes drived from a five-parent diallel mating set contain khazar, sepidrood, hashemi, alikazemi and nematt were evaluat...

considering the increasing rice consumption in the world and also the excessive application of pesticides to increase production, an experiment was conducted to determine the pesticide residues and their effects on nitrogen, potassium and phosphorus content of hashemi, khazar and gohar (sa13) rice cultivars, in a factorial design at randomized complete block design with three replications. in t...

this paper is about to discover the roots of formation of one of the political and social phenomena called political party in a particular period of iranian contemporary history. in the light of this kind of study we can go beyond the superficial and general analyses which are the characteristic of traditional and under developed societies unfortunately these analyses are used to justify all th...

quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...

We investigated maximal Prym varieties on finite fields by attaining their upper bounds on the number of rational points. This concept gave us a motivation for defining a generalized definition of maximal curves i.e. maximal morphisms. By MAGMA, we give some non-trivial examples of maximal morphisms that results in non-trivial examples of maximal Prym varieties.
