genotype by environment interaction is one of the most important subjects in crop improvement, so that different statistical measures have been proposed to estimate this interaction. in the present study, nine varieties and hybrids of spring rapeseed were evaluated in five warm dryland areas including sarpol-e-zahab, gonbad, gachsaran, pol-e-dukhtar and masjedsoliman in two growing seasons 2002...
To obtain high yield and stable genotypes, 18 durum wheat cultivars and promising lines along with two commercial durum (Behrang) and bread wheat (Chamran) as check cultivars, were evaluated in four warm and dry regions in Iran including Darab, Ahvaz, Khoramabad and Dezful during two cropping seasons (2013-2015). The experiments were conducted as a RCBD with three replications. Seed yield and s...
با پیشرفت تکنولوژی و کاهش ابعاد ترانزیستور، تلرانس پارامترهای ساخت مدارات الکترونیک افزایش یافته و باعث کاهش ضریب yield می شود. در طراحی مدارات الکترونیک، طراح عموما مقادیر نامی را برای دست یابی به عملکرد مطلوب استخراج می کند، در حالی که، در عمل یک ناحیه تلرانس، به دلیل فرآیند های تصادفی حین فرآیند های ساخت، وجود دارد که بایستی در طراحی لحاظ گردد. الگوریتم های بهینه سازی طراحی تلرانس، ناحیه تلر...
the interaction of genotype × environment effect, because of disordering effect on genotypes selection has special importance in plant breeding programs. therefore to better selection, yield and yield stability might be considered simultaneously. in order to study of grain yield stability and the evaluation of different selection methods efficiency, 18 advanced barely lines were studied in four...
To study the grain yield stability of winter type canola cultivars (Brassica napus L.) in multiple environments, 18 winter type canola cultivars were evaluated in a complete randomized block design with four replications. The study was conducted in two years and eight cold and temperate regions of Iran. Simple and combined analysis of variance revealed significant differences among genotypes. M...
Genotype-environment interaction for plant breeders has been important as it is a complex issue in breeding for high yield varieties and releasing new genotypes. In order to assess adaptability and stability of sunflower varieties in different climate conditions, twelve cultivars were investigated in Karaj, Shiraz, Birjand, Kashmar and Arak in randomized complete block designs with three replic...
Yield losses occurring at the field level, whether due to plant diseases or abiotic stresses, reveal reduced stability of the crop yield potential. The paper argues that the stability of crop yield potential is a trait with a clear genetic component, which can be successfully selected for at the single-plant level and incorporated into high-yielding cultivars. Two novel selection equations with...
Stability Analysis of Genotype × Environment Interaction Effect on Sugar Yield in Sugar Beet Hybrids
Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...
Evaluating the promising genotypes in different years and locations is performed to identify stable and adaptable genotypes with high yield potential. For this purpose, three genotypes of rapeseed derived from crossing of three varieties named Foseto, Option 500 and Goliath were planted with check variety (Hyola 401) in three locations (Sari, Behshar and qarakheil) using randomized complete blo...
in order to study genotype environment interaction (g e) and to identify high yielding and stable genotypes, 17 safflower (carthamus tinctorius l.) genotypes were evaluated in a randomized complete block design with 3 replications, at 9 research stations during four consecutive cropping seasons (2003–06) under rainfed conditions. on the basis of ammi analysis of variance, effects of genotyp...
