for evaluation of iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 iranian onion morphotypeswere collected from east azarbaijan (redazarshahrmorphotypes), tehran (red rey morphotypes), razavi khorasan (red neyshaboormorphotypes) and zanjan (gholyghese morphotypes). these onion morphotypes were planted inrcbd design in four replications in seed and p...

background : phlebotomus sergenti s.l. is considered the most likely vector of leishmania tropica in iran. although two morphotypes- p. sergenti sergenti (a) and p. sergenti similis (b)-have been formally described, further morphologi­cal and a molecular analysis of mitochondrial cytochrome oxidase i (mtdna-coi) gene revealed inconsistencies and suggests that the variation between the morphotyp...

We discuss, from the aspect of phylogeny, the interrelationships of the phytolith types in plants from the main taxonomical groups (algae, lichens, horsetails, gymnosperms, and floral plants) with homologues of known proteins of biomineralization. Phytolith morphotypes in various phylogenetic plant domains have different shapes. We found that, in ancient types of plants (algae, horsetails, and ...

The effect of three concentrations of silver nitrate on anther culture embryo production was studied in 27 morphotypes of Brassica oleracea. Embryo yields were significantly increased in the majority of the morphotypes by the addition of silver nitrate to the media. Embryo yields were not increased in only a few of the almost nonembryogenic accessions. The magnitude of the response to silver ni...

This study was conducted to examine the variabilities in the chronology of vegetative and reproductive development of weedy rice (Oryza spp.) in comparison with commercial varieties. Data at different growth stages of 14 weedy rice morphotypes and 4 commercial rice varieties were recorded and analysed. Plant height of all weedy rice morphotypes were observed to be significantly higher compared ...

genetic diversity of 22 morphotypes of diploid wheat (t. urartu) was investigated using morphological traits and rapd markers. morphological characterizations were carried out based on 17 traits and statistical parameters of dispersion and diversity of agronomic traits were calculated. statistical analysis showed significant differences for all characters among morphotypes. dendrograms were gen...

A few marine cases have demonstrated morphological and genetic divergence in the absence of spatial barriers to gene flow, suggesting that the initial phase of speciation is possible without geographic isolation. In the Bocas del Toro Archipelago of the Atlantic Coast of Panama, we found two morphotypes of the scleractinian coral Favia fragum with opposing depth distributions. One morphotype fi...

Giant freshwater prawn (GFP) Macrobrachium rosenbergii is unique with males categorized in five different morphotypes (small claw, orange claw, blue claw, old blue claw and no claw males) and females in three reproductive statuses (mature ovary, berried and spawned females). In the present study we examined genetic inheritance of female and male morphotypes, their body weights and genetic assoc...
