Sugarcane cultivation is hindered by several biotic constraints of which viral disease plays a major disaster. This study was carried out to evaluate the virus situation sugarcane germplasm in western Cameroon, consisting three regions (Southwest, Northwest and West region). A survey 66 villages these regions. Landraces identified included SMU58, SBK36, SNC16, NBfPc48 NBfAg53. Representative sa...

Domestication and genetic improvement of maize improve yield stress tolerance due to changes in morphological physiological properties, which likely alter rhizosphere microbial diversity. Understanding how the evolution germplasm impacts its rhizobacterial traits during growth stage is important for optimizing plant-microbe associations obtaining gain domesticated germplasms. In this study, a t...

Maize is one of the most important staple crops in highlands Andean region Ecuador, Peru, and Bolivia. Most seeds come from landraces, with their own kernel characteristics. The kernels are used for elaboration traditional dishes other elaborates human consumption. In this region, maize breeding conducted mainly by public institutions. review, we outline methodology that has been programs (MBPs...

Nowadays, agriculture is under the pressure of climate change and new pathogen outbreaks while farmers are requiring breeders to develop more resistant resilient genotypes. The genetic base for breeding may be increased through appropriate conservation, description characterization local varieties germplasm collections that have never been used in breeding, which could sources useful alleles. I...

Black soybean landraces that had been cultivated in Tanba region and the neighboring regions and conserved black soybean landraces, including those from other regions in Japan, were used in this study. The polymorphisms of 78 SSR markers in nuclear DNA and 6 SSRs in chloroplast DNA were analyzed in the black soybean landrace populations. The result of phylogenic analysis revealed that the black...
