Abstract Background Improvement of wheat gerc Triticum aestivum L.) yield could relieve global food shortages. Kernel size, as an important component 1000-kernel weight (TKW), is always a significant consideration to improve for breeders. Wheat related species possesses numerous elite genes that can be introduced into breeding. It thus vital explore, identify, and introduce new genetic resource...

to evaluate the morphological diversity of some almond cultivars and genotypes, an experiment was carried out on 55 iranian and foreign genotypes. twenty-nine quantitative and qualitative characteristics of nuts and kernels as well as 4 phenotypic characteristics of almond trees were evaluated. analysis of variance and means comparisons indicated that all the characteristics of the examined cul...

We show that theMinimal Length-Bounded L-But problem can be computed in linear time with respect to L and the tree-width of the input graph as parameters. In this problem the task is to find a set of edges of a graph such that after removal of this set, the shortest path between two prescribed vertices is at least L long. We derive an FPT algorithm for a more general multi-commodity length boun...

in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...

Kernel size-related traits, including kernel length, width, and thickness, are critical components in determining yield quality maize (Zea mays L.). Dissecting the phenotypic characteristics of these discovering candidate chromosomal regions for potential importance improvement. In this study, a total 139 F2:3 family lines derived from EHel B73, distinct line with extremely low ear height (EHel...

In insects, the frequency distribution of the measurements of sclerotized body parts is generally used to classify larval instars and is characterized by a multimodal overlap between instar stages. Nonparametric methods with fixed bandwidths, such as histograms, have significant limitations when used to fit this type of distribution, making it difficult to identify divisions between instars. Fi...

in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...
