due to its wide adaptability, chickpea is considered as an important crop in arid, semi-arid and in marginal lands. most important factors which limit yield of chickpea are short length of physiological growth period and susceptibility to cold and diseases, especially ascochyta rabie. releasing a chickpea cultivar with high yield and good characteristics such as cold tolerance, resistance to di...

Understanding the evolutionary mechanisms that maintain genetic variation in natural populations is one of the fundamental goals of evolutionary biology. There is growing evidence that genotype-by-environment interaction (G 9 E) can maintain additive genetic variance (VA), but we lack information on the relative performance of genotypes under the competitive situations encountered in the field....

Sweet sorghum is a special purpose with sugar-rich stalk, almost like sugarcane. The objective of this work was to evaluate the phenotypic stability and adaptability sweet genotypes, in different Brazilian regions, for production bioethanol. Twenty-five genotypes were evaluated 10 environments distributed Southeast, Midwest, Northeast, Southern regions Brazil. experimental design randomized com...

Bacterial wilt of common bean caused by Curtobacterium flaccumfaciens pv. flaccumfaciens is an important disease in terms of economic importance. It reduces grain yield by colonizing xylem vessels, subsequently impeding the translocation of water and nutrients to the superior plant parts. The existence of physiological races in C. flaccumfaciens pv. flaccumfaciens has not so far been reported. ...

cantaloupe is a common crop and relatively important in iran which show high genetic diversity. forty nine genotypes including seven iranian endemic cantaloupes rishbaba, shahabadi, samsori, dastjerdi, magasi, tiltorogh and savei and their direct and reciprocal crosses were evaluated during two years using triple lattice design. results indicated the positive and significant correlations betwee...

Information about the response of poplar (Populus spp.) genotypes to landfill leachate irrigation is needed, along with efficient methods for choosing genotypes based on leachate composition. Poplar clones were irrigated during three cycles of phyto-recurrent selection to test whether genotypes responded differently to leachate and water, and to test whether the methodology had merit as a tool ...

data on 300 kermani sheep from kermani breeding center of shahrbabak were utilized in the present research. horizontal polyacryle amide electrophoresis was employed to detect polymorphism of transferrin and albumin, while acetate cellulose being utilized for hemoglobin. three genotypes of hemoglobin were observed(aa, ab and bb with respective frequencies of 4.6, 43.8 and 51.6). frequency of a a...
