Genetic diversity and phylogenetic relationships among 22 local cowpea (Vigna unguiculata) varieties and inbred lines collected throughout Senegal were evaluated using simple sequence repeat molecular markers. A set of 49 primer combinations were developed from cowpea genomic/expressed sequence tags and evaluated for their ability to detect polymorphisms among the various cowpea genotypes....
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
to identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between norstar and zagros cultivars were evaluated in a randomized complete block design with three replications. the measured characters consisted of peduncle weight, ...
Information about combining ability of inbred lines and genetic variance components of different agronomic traits is a prerequisite for improving the productivity of sunflower hybrids. For this purpose, 20 hybrids obtained from the crosses between five cytoplasmic male sterile lines with four fertility restorer lines were evaluated in a randomized complete blocks design with three replications ...
Hybrid rice has an average 15 % to 20 yield advantage over inbred lines. The availability of stable cytoplasmic male sterility system is vital for commercial hybrid rice. experiment was conducted develop japonica type CMS lines national varieties. National varieties were tested determine as maintainer, or restorer features via test cross. crosses made by using 19 and 21 1 line. All which are de...
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...
Traits related to seed quality have an important role in production of durum wheat. To estimate the heritability of protein content, semolina content, Zeleny number, seed hardness, SDS, dry and fresh gluten content, gluten index, and also to investigate the relationship of these traits in durum wheat, a recombinant inbred lines (RILs) population including 94 recombinant inbred lines (F10), two ...
