In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...
In order to decrease effect of genotype × environment interaction, yield and yield stability should be considered simultaneously. In present study, 24 bread wheat genotypes were evaluated in Gorgan and Gonbad agricultural stations in 2012-13 and 2013-14 cropping seasons. Experiments were conducted based on complete block designs with three replications at 6th December and February. Combined ana...
In order to investigation of genotype - environment interaction is essential for selecting compatible and stable genotypes in plant breeding. For this order analysis of genotype × environment interaction and identify barley stable genotypes for warm and humid regions, this study conducted in a randomized complete block design with 4 replications and 16 genotypes with two check cultivars in ...
in order to determinate appropriate stability parameters, six statistics were studied for flower yield stability of 35 rosa damascena landraces in 8 locations over two years (2007-8) in iran, using a randomized complete blocks design with 3 replications. a positive correlation between environmental variance (s2) and flower yield suggested that only low yield landraces develop a similar phenotyp...
selection of superior varieties of wide adaptability over diverse farming environments is of high importance, prior to any varietal recommendation. in order to study yield stability of alfalfa, 17 ecotypes were evaluated during 2004-2005 and 2005-2006 growing seasons at 10 research stations. each trial was carried out according to a completely randomized block design of 3 replications with fres...
Durum wheat (Triticum turgidum L.), like most other crops, is affected by various stresses. Therefore, cultivars that, in addition to the ability to produce higher yields, can maintain their yield potential in different years and locations are considered superior cultivars. In order to obtain high-yielding and stable genotypes of durum wheat, 16 lines with two control cultivars Dehdasht and Sey...
The objectives of this study were to analyze genotype by environment (GE) interactions effects on the yield of barley lines and varieties, identifying salinity tolerant genotypes with stable yield and also evaluating genotype (G), environments (E) and GE interactions using different stability parameters. The research was set up as two Randomized Complete Block design with three replications at ...
The challenge of the interaction of genotype × environment is one of the main issues in plant breeding. Various statistical methods to estimate the interaction of genotype × environment and choice the stable and productive genotype(s) have been introduced. In this study, 14 lentil genotypes along with two controls (Sepehr and Gachsaran cultivars) were evaluated during four growing seasons (2016...
Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...
In order to evaluate the grain yield stability of 21 oat genotypes, 13 experiments carried out during 6 years (from 2009 to 2015) and across 4 environments in the west of Iran. Five of them were carried out by the author of this thesis during 2013-2015 using a completely randomized block design with three replications under three conditions including irrigated, drought stress and rainfed at the...
