A novel internal state recovery attack on the whole Grain family of ciphers is proposed in this work. It basically uses the ideas of BSW sampling along with employing a weak placement of the tap positions of the driving LFSRs. The currently best known complexity trade-offs are obtained, and due to the structure of Grain family these attacks are also key recovery attacks. It is shown that the in...
Half diallel crosses of eight bread wheat cultivars were used to estimate the genetic parameters and types of genetic control for yield and yield components, and to determine the effects of environmental factors on these parameters. Parents and their F2 hybrids were grown in a randomized block design under irrigated and stressed (terminal drought) conditions. For all traits, except for number o...
With the aim of comparing the grain yield and yield components of 16 oilseed rape (Brassica napus L.) mutant lines with cultivars Talayeh, Zarfam, Express and Okapi as check cultivar an experiment was conducted based on randomized complete block design with three replications during 2015-2016 cropping season in experimental field of Seed and Plant Improvement Institute (SPII) in Karaj. Analysi...
This study was designed and implemented to investigate the yield and agronomic characteristics in three differently maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol (South-West of Iran) and Isfahan (Central Iran) in 2014 and 2015, respectively, using a split-pl...
Drought is one of the main dangers for optimum production of wheat. Achieving optimal results in breeding programs require to make informed choices of parents based on general and specific combining ability.In order to study the genetic characteristics, general and specific combining abilities and gene actions under drought stress conditions, a half diallel cross including 9 varieties of wheat ...
Finding the appropriate parents for breeding programs is the main aim of selecting in drought tolerant crops and landraces under stresses conditions. In present survey, eigthey wheat landraces and varieties from different areas of Iran were evaluated in Gorgan agricultural research station (as a normal or potential yield) and Mazrae-Nemoneh (as under stress condition) during two years (1999-200...
Rice (Oryza sativa) grain shape, which is controlled by quantitative trait loci (QTL), has a strong effect on yield production and quality. However, the molecular basis for grain development remains largely unknown. In this study, we identified a novel QTL, Slender grain on chromosome 7 (SLG7), that is responsible for grain shape, using backcross introgression lines derived from 9311 and Azucen...
Six Iranian rice cultivars (Binam, Domsiyah, Shahpasand, Sepidrud, Khazar and Valed 46) were crossed in 1989 in the Iranian Rice Research Institute in Rasht, Iran in a full-diallel design. The F1 progenies together with parents were transplanted in a CRBD in the 5 x 0.75 m plots at plant density of 25 x 25 cm (60 plantlets per plot) in 3 replications. Part of this research was published in 1994...

Correlations among ‘special’ and ‘general’ grain boundaries are studied on two-dimensional networks, by examining the configurational entropy of boundary structures as well as percolation thresholds. Consideration of crystallographic constraints at various length scales reveals that higher-order constraints play a role in boundary connectivity and network structure. Implications for grain bound...
