To locate the genes controlling adaptability in bread wheat using AMMI (additive main effect and multiplicative interaction) model, twenty-one substitution lines derived from the parents Chinese Spring (recipient) and Chayan (donor) were used in a randomized complete block design with three replications in three different environments in the Agricultural College of Razi University, Kermanshah, ...

based on the evaluation of two human cell lines, hela and chang, abeuploidy and several marker chromosomes were found in both cells. the morphological characteristic of marker chromosomes of chang cells was distinctly different from hela. certain submetacentric marker chromosome was frequently present among 80% of marker chromosomes of chang cells which distinguished this line from hela, which ...

the polygene chromosomal pattern together with the somatic and meiotic chromosomes of the autogenous tehran strain of culex pipiens molestus is described. the first and third chromosomes are metacentric, the second one is slightly submetacentric. each chromosome has well-defined, large puffed char­acteristic centromeres. randomly distributed asynaptic regions on the polytens chromosomes are ind...

  Preparation of chromosome spreads and karyotype analysis in Blicca bjoerkna transcaucasica were carried out using 0.01% solution of colchicines and Phytohaemagglutinin (PHA) (20 µg g-1 body weight). The gill and kidney tissues were collected and let to stand in a hypotonic solution of 0.075 M KCl and then treated with a fixative (Carnoy's solution) in three steps. The chromosomes spreads were...

In this study, the karyo-systematic studies on the Iranian wild almond species A .communis L., A. corduchoruom Bornm., A. trichamygdalus woronow, Amygdalus lycioides Var. horrida Spach were done by the karyological methods. The meristem cells of the root tip were used for these studies. In each species, ten suitable metaphase plates were chosen and photographed so that the morphology of the chr...

The domestic water buffalo (Bubalus bubalis) is an economically important livestock species in many Asian and Mediterranean countries. Two types of water buffalos are river and swamp buffaloes. Genetically, the swamp buffalo has 48 chromosomes (2n = 48) and the river buffalo has 50 chromosomes (2n = 50). Khuzestan province is one of the important centers of buffalo farming in ...
