In order to study seed yield and seed yield components in bean under reduced irrigation condition and assessment drought tolerance of genotypes, 15 lines of White beans were evaluated in two separate RCB design with 3 replications under stress and non stress conditions. Analysis of variance showed that there were significant differences among varieties in terms of traits under study, indicating...

beauveria bassiana (balsamo) vuillemin is an important natural regulator of insect populations. identification of a suitable molecular marker for detecting a virulent phenotype on a target pest would be useful in screening for effective isolates against the pest. nine isolates of b. bassiana were tested for their virulence to adults of tribolium castaneum (herbst) in laboratory bioassay with 1×...

in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...

Successful hybrid cultivar breeding is depend on the high genetic diversity of plant sources, as well homozygous and genetically distant lines requiring hybridization. The aim this study to determine distance between inbred pepper (Capsicum annuum L.) in order increase efficacy program. In study, distances 44 bell peppers 35 banana were investigated using SRAP (Sequence Related Amplified Polymo...

Cluster analysis is a way of “slicing and dicing” data to allow the grouping together of similar entities and the separation of dissimilar ones. Issues arise due to the existence of a diverse number of clustering algorithms, each with different techniques and inputs, and with no universally optimal methodology. Thus, a framework for cluster analysis and validation methods are needed. Our approa...
