in order to study the effect of genotype × environment interaction and stability of sugar beet varieties, four cultivars, including shirine, zarghan, laetitia and 7112 hybrid were planted in five major areas near to sugar beet factory of biseton as kangavar, sahneh, chamchamal, dinavar and ravansar for three years (2006-2008) using a randomized complete block designs, with three replications. a...

background and objectives: the development of high yielding cultivars with wide adaptability is the ultimate aim of plant breeders. however, attaining this goal is made more complicated by genotype-environment interactions. the genotype by environment interaction is a major problem in the study of quantitative traits because it complicates the interpretation of genetic experiments and makes pre...

common bacterial blight (cbb) caused by xanthomonas axonopodis pv. phaseoli is a serious disease of bean fields in iran and the world. chemical control of cbb is inefficient, therefore the use of resistant genotypes with stability production is the most suitable alternative. stability and adaptability of 26 bean genotypes yield in the presence and absence of cbb were evaluated in agricultural r...

Chickpea (Cicer arietinum L.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. In addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. In order to screen drought tolerant genotype in Chickpea, twenty genotypes were tested under rainfed and irrigated...

based on principal component analysis (pca), gge biplot analysis is an effective method to fully assess multienvironmental yield trials (mets). additive main effects and multiplicative interaction (ammi) is an alternative method for assessing phenotypic stability and adaptability. in this research, met data of 14 maize inbred lines were used to perform ammi and gge biplot analyses. these genoty...

Historically in plant breeding a large number of statistical models has been developed and used for studying genotype × environment interaction. These models have helped plant breeders to assess the stability of economically important traits and to predict the performance of newly developed genotypes evaluated under varying environmental conditions. In the last decade, the use of relatively low...
