If C is a subclass of the class of claw-free graphs, then C is said to be stable if, for any G ∈ C, the local completion of G at any vertex is also in C. If cl is a closure operation that turns a claw-free graph into a line graph by a series of local completions and C is stable, then cl(G) ∈ C for any G ∈ C. In the talk we consider stability of hereditary classes of claw-free graphs defined in ...
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 ...
Genotype-environment interaction (GEI) is very important for breeders. It considered a complicated issue in breeding programs to obtain stable and high-yielding genotypes release new genotypes. This study was conducted achieve genotype that adaptive climatic conditions of potato-producing regions Iran. A total 20 potato lines along with five commercial varieties (Savalan, Agria, Caesar, Luta Sa...
The performance of a mixed microbial community was tested in lab-scale power-to-methane reactors at 55 °C. main aim to uncover the responses starvation and stoichiometric H2/CO2 supply as sole substrate. Fed-batch were inoculated with fermentation effluent thermophilic biogas plant. Various volumes pure gas mixtures injected into headspace daily process parameters followed. Gas composition meas...

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...
In this paper we study bifurcations in predator-prey systems with seasonal prey harvesting. First, when the seasonal harvesting reduces to constant yield, it is shown that various kinds of bifurcations, including saddle-node bifurcation, degenerate Hopf bifurcation, and Bogdanov– Takens bifurcation (i.e., cusp bifurcation of codimension 2), occur in the model as parameters vary. The existence o...
The discrepancies across test sites and years, along with the interaction between cultivar and environment, make it difficult to accurately evaluate the differences of the sugarcane cultivars. Using a genotype main effect plus genotype-environment interaction (GGE) Biplot software, the yield performance data of seven sugarcane cultivars in the 8th Chinese National Sugarcane Regional Tests were ...
abstract the present study was aimed to investigate the planting dates effects on yield associated traits and also determining stability of the result of factor analysis and stepwise regression analysis in different planting dates of rapeseed genotypes at biekol agriculture research station during 2011-12 cropping season. result of split plot analysis exhibited significant genotypes effects for...
