The selection efficiency of the most desirable safflower genotypes can be improved by incorporating the graphical methods and statistical analysis. This experiment was carried out to determine grain yield stability of safflower genotypes using the graphical and statistical methods. Twenty safflower genotypes were evaluated in Chachsaran, Choram, Behbehan and Dehdasht using randomized complete b...

In order to evaluate the stability and response of advanced lines of grass pea under rainfed conditions, fourteen lines were studied in a randomized complete block design with three replications at three research stations located in Khoram Abad, Kermanshah and Gachsaran during 2005-2008. Based on combined ANOVA analysis the effects of line, year × location, line × location and line × year × loc...

In order to study tuber yield stability of 15 potato genotypes, this research was carried out using randomized complete block design with three replications in three different research stations in Iran during two growing seasons. The combined analysis of variance indicated that the main effects of genotype (G), environment (E) and their interactions genotype and environmen (G×E) were highly sig...

To determine yield stability and to evaluate genotype interaction with environment interaction, 18 genotype of barley (Hordeum vulgare L.) and a control group were evaluated in a randomized complete block design with 4 replications in 3 successive years (1997-2000) at 10 research stations. Simple and combined analysis of variance revealed significant genetic differences between yield genotypes ...

To facilitate the interpretation of data from a genotype by environment experiment (GE), a cluster method is proposed to group genotypics according to their response to the environments especially when the GE interaction is large. The interaction structure of two-way classification data often can be identified if the data stratified into homogeneous subsets. In this paper four GE interaction cl...

Genotype by environment interaction is one of the complicated issues in plant breeding programs for development of high-yielding with yield stability genotypes. To evaluate seed yield and yield stability of oilseed rape in four southern and northern warm regions of Iran (Zabol, Gorgan, Haji Abad and Sari), nine open pollinated spring oilseed rape lines together with seven cultivars were evaluat...

Combinining features of the best linear unbiased predictions (BLUP) and additive main effects and multiplicative interaction (AMMI) through “Weighted average of absolutescores of best linear unbiased predictions” (WAASB) index in multi-environment experiments may lead to more percise evaluation of genotypes and assessment of genotype × environment interaction. In the present study, the seed yiel...

Extended Abstract Introduction and Objective: Brassica napus (L.) one of the most important oilseeds in temprate climates. In the most breeding programs, especially when comparing several genotypes in different environments, due to the interaction of genotype×environment, genotypes show different performances in different environments. Therefore, to accurately estimate grain yield, multi-envir...

One of the most complicated issues in plant breeding programs is genotype by environment interaction. To evaluate seed yield stability of 18 chickpea promising lines, a field experiment was conducted using randomized complete block design with four replications in two cropping seasons (2018-19 and 2019-2020) in four research stations (Maragheh, Kurdistan West Azerbaijan and Hamedan), Iran.
