the selection of high yielding varieties with good stability‏ ‏is an important objective in rice breeding ‎programs. the grain yield of eight rice lines with a check (nemat) were compared‎‏ ‏on six locations of gilan ‎and mazandaran provinces during two years, using rcbd with four replications. combined analysis of ‎variance showed that the effect of variety and year ‎‏×‏‎ location ‎‏×‏‎ variet...

study of genotype by environment interaction (gei) has assumed great importance in genotype testing programs due to yield performance of a genotype is a result of interaction between genotype and environment. gei occurs when the performance of the genotypes is not consistent from one environment to another. therefor, 17 barley genotypes with three check cultivars (wa 2196-68/ny6005-18,f1//scoti...

Arun Shukla received his master's degree in Biotechnology from the Jawaharlal Nehru University in New Delhi, and joined the lab of Nobel laureate Hartmut Michel at the Max Planck Institute of Biophysics in Frankfurt, Germany, for his PhD. He then moved to the United States for his postdoctoral work with Robert Lefkowitz at Duke University (Durham, NC) in a very close collaboration with Brian Ko...

The proliferation of system level design methodologies and frameworks is a direct result of the efforts in dealing with the productivity gap. Consequentially, System Level Design Languages such as SystemVerilog and SystemC are particularly fit for high level design methods such as design space exploration and assisted design refinement. However, to draw full benefit of these methods requires th...

Clonal stability of tree dryness was evaluated in eleven clones of Hevea brasiliensis at the Rubber Research Institute of Nigeria. The experimental design was the randomized complete block with three replicates and ten trees per replicate. The clones were evaluated in three locations. Four stability parameters were applied. The stability parameters were: environmental variance, regression index...
