a set of 29 persimmon genotypes were characterized using morphological characters and rapd markers. some fruit traits of: fresh weight, fruit length and diameter, firmness, fruit juice ph, ta, tss, flavor index, fruit skin and flesh color, seededness, leaf length and width were evaluated. analysis of variance for the investigated characters showed that genotypes were significantly different. re...

Tribes of the leafhopper subfamily Typhlocybinae have traditionally been defined based on differences in hind wing venation, but forewing venation also differs among some tribes. Here we used geometric morphometric analysis to determine whether previously recognized tribes can be distinguished configuration veins. Focusing apical area male right forewing, 76 semi-landmarks six curves correspond...

Cellular manufacturing system is the formation of optimised machine cells, which forms part families with similar processing requirements and associates machines into machine cells in order to optimise the overall production process. To effectively solve this problem a hybrid novel approach is demonstrated in this paper, which is based on weighted average linkage clustering algorithm and fuzzy-...

We will use a variation of UPGMA in UPGMA we have a distance matrix, in each iteration we take the pair i, j with the minimal distance: ∀k, l : di,j < dk,l and create a new node which is their parent.In the UPGMA algorithm the new distances for this node is the average of the two distances of it’s children : ∀l : Di+j,l = 12 (di,l + dj,l). We will talk about a very similar idea for clustering g...

in order to evaluate the genetic diversity of common bean (phaseolus vulgaris l.) and the relationships between studied characteristics with seed storage proteins, 60 genotypes with three colors (white, red and pinto bean) were studied using an augmented design with three blocks and four varieties as controls. the majority of studied traits were significantly different between large and small s...

The experiment was conducted at Plant Genetic Resources Centre, Bangladesh Agricultural Research Institute (BARI) and the genotypes were collected from Chapainawabganj, most mango variability rich district in Bangladesh. molecular characters of germplasm assessed by using six simple sequence repeat (SSR) markers. Polymerase chain reaction (PCR) amplification DNA isolated 60 with 6 SSR primers p...

Iris belongs toIridaceae family and it is monocotyledon. Iris is one of the important ornamental and medicinal plants. 34 iris genotypes (14 species) collected from different provinces of Iran were planted at National Institute of Ornamental Plants (NIOP) Iran. All of the species evaluated for 15 quantitative traits and 30 qualitative traits. Results showed that the highest positive correlation...

Distance-based methods such as UPGMA (Unweighted Pair Group Method with Arithmetic Mean) continue to play a significant role in phylogenetic research. We use polyhedral combinatorics to analyze the natural subdivision of the positive orthant induced by classifying the input vectors according to tree topologies returned by the algorithm. The partition lattice informs the study of UPGMA trees. We...
