The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...

understanding the implication of genotype-by-environment interaction (gei) and improving stability of crop yield in a target production environment is important in plant breeding. in this research, we used the ammi (additive main effects and multiplicative interaction) model to identify the stable genotype(s) by predictive accuracy of yield data. results of this study indicated that the fgh tes...

in order to  study of environment × genotype interaction and selection of stable and high yielding and cold  tolerant chickpea lines, this study carried out  with 13 chickpea genotypes along with one local check (jam) in a rcb design with four replications during three cropping seasons (2009-2012) in agricultural research station of maragheh (dari). the genotypes were exposed to cold temperatur...

The preparation of nanocellulose fibers (NFs) is achieved through pretreating cellulose in a NaOH/urea/thiourea solution, and then defibrillating the fibers through ultrasonication, resulting in a high yield of 85.4%. Extensive work has been done to optimize the preparation parameters. The obtained NFs are about 30 nm in diameter with cellulose II crystal structure. They possess high thermal st...

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...
