Genetic relatedness among Indian farmers’ rice varieties were assessed using 24 distinct rice microsatellite markers. The 41 rice genotypes studied included 14 improved varieties and 27 landraces collected from different parts of India. The number of alleles per microsatellite locus ranged from 2 to 4, averaging 2.79 alleles per locus. Polymorphism information content (PIC) values ranged from 0...
When two communicating vessels are filled to a different height with liquid, the two levels equilibrate because the liquid can flow. We have looked for such equilibration with solid (4)He. For crystals with no grain boundaries, we see no flow of mass, whereas for crystals containing several grain boundaries, we detect a mass flow. Our results suggest that the transport of mass is due to the sup...
In order to investigate the effect of nitrogen management on morphophysiological traits, yield and yield components of corn hybrids, the present experiment was carried out in a split plots arrangement in a randomized complete blocks design with three replications in a field located in Ahvaz city during the crop year 2016-2017. Experimental treatments consisted of nitrogen fertilizer management ...
drought is the most restricting factor in agricultural production in arid and semi-arid regions. this research was conducted on 19 facultative and winter wheat genotypes grown under normal irrigation (n), early post-anthesis (s1), and late post-anthesis (s2) drought stress conditions. the experiments were conducted at karadj, arak, and jolgehrokh agricultural research stations in iran, during 2...
Rhyzopertha dominica is one of the most damaging insect pests in grain elevators and causes millions of dollars worth of stored grain losses annually in the USA. A simulation model was developed for predicting R. dominica population dynamics in concrete grain bins. The model used a two-dimensional representation of a cylindrical concrete bin (33m tall 6.4m wide), and used hourly weather data to...
Increasing grain yield potential in wheat has been a major target of most breeding programs. Genetic advance has been frequently hindered by negative correlations among yield components that have been often observed in segregant populations and germplasm collections. A tetraploid wheat collection was evaluated in seven environments and genotyped with a 90K SNP assay to identify major and stable...
Decrease of water resources in temperate regions of Kermanshah province has caused the maize cultivation area decreased form 45 thousand hectares in 2008 to 7 thousand hectares in the crop year of 2016. This study aimed to evaluate and selecting drought tolerant hybrids and increased irrigation water efficiency using eight commercial maize hybrids (KSC 704, KSC 705, KSC 703, KSC 700, KSC 6...
