Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
We describe and test a Markov chain model of microsatellite evolution that can explain the different distributions of microsatellite lengths across different organisms and repeat motifs. Two key features of this model are the dependence of mutation rates on microsatellite length and a mutation process that includes both strand slippage and point mutation events. We compute the stationary distri...
landmark based geometric morphometrics and comparison of meristic characters was used to understand potential differences between populations of waspi in mashkil and mokran basins. 97 specimens of waspies were caught (64 from mashkil river and 33 from sarbaz river). 14 landmarks were digitized on pictures taken from left side of specimens and meristic characters were counted. data were analyzed...
Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Insects can estimate distance or time-to-contact of surrounding objects from locomotion-induced changes in their retinal position and/or size. Freely walking fruit flies (Drosophila melanogaster) use the received mixture of different distance cues to select the nearest objects for subsequent visits. Conventional methods of behavioral analysis fail to elucidate the underlying data extraction. He...
Pterocephalus (Caprifoliaceae) consists of 30 species worldwide, mainly distributed in the temperate regions of the northern hemisphere, of which 14 species were reported from Iran, including five endemic ones. In this study, 35 leaf-related traits and 30 peduncle-related traits were investigated by light microscopy of 15 samples from 11 Iranian species of Ptreocephalus. Our results showed that...
Olyra saginata, new species, is described from the Kaladan [=Kolodyne] River system in Mizoram, northeast India. It differs from congeners in having the following unique combination of characters: interorbital distance 27.9-35.9% HL; 54-66 lateral-line pores; body depth at anus 10.5-12.0% SL; length of adipose-fin base 17.3-22.4% SL; adipose fin separate from upper principal caudal-fin rays; po...
In order to study inheritance of traits (Height, Peduncle length, Extrusion peduncle length, Diameter first internode, Diameter secondary internode, Diameter third internode length of secondary internode, length of third internode) associated with height in bread wheat, seven cultivars of bread wheat with their F1 progenies produced through a half diallel mating design were planted in a randomi...
