Identification of desirable maintainers and potential restorers in a hybrid rice breeding program is the dire need for development hybrids. Seventeen (17) cytoplasmic male sterile (CMS) lines (15 imported from IRRI 02 locally developed by RRI, KSK) were crossed with one hundred sixty (160) testers to identify their genetic nature behave as restorer or maintainer year 2017 2018. A total test cro...

Spinach is one of the most important green leafy vegetables (Spinacia oleracea L.). The qualitative and quantitative trait of the spinach depends on the weather conditions. Screening the foreign accession compare with Iranian ones is necessary for breeding purposes. In order to study the vegetative characteristics of 44 endemic and foreign accessions, an experiment was conducted in a r...

'Candidatus Liberibacter solanacearum' (Lso), an uncultivable phloem-limited phytopathogenic bacteria, is known to be associated with Zebra Chip disease (ZC), which represents a major threat to potato production in the US and elsewhere. This pathogen is transmitted by the phloem-feeding potato psyllid, Bactericera cockerelli Sulc (Hem. Triozidae). Currently, there are no reports of resistance t...

Assessment of genetic diversity and individual relationships in rice (Oryza sativa) germplasm collections seems to be necessary for future rice breeding program. In order to understand genetic relationships of 30 rice genotypes, nine morphological traits, seven physicochemical properties and twelve RAPD primers were used for study of 30 rice genotypes. Among morphological traits, numbe...

increasing product marketability and introduction of new cultivars for fresh consumption of apple is the world's most important breeding objectives. in this study, the qualitative and quantitative characteristics of the genotypes from cross between red spur and golab-e-kohanz apple cultivars were evaluated. a total of 19 traits including fruit attributes (firmness, fruit weight,...) and th...

Limited genetic variability is a major problem in rapeseed breeding, whose strict selection, limited geographical range and short period of domestication has led to reduction phenotypic diversity. Assessing specific populations for the greatest diversity many traits simultaneously, requires evaluation multi-feature characteristics. The aim this study was estimate DH (doubled haploid) lines two ...

Sugarcane is the main sugar producing crop in Bangladesh. However, improvement of this crop through breeding is limited due to lack of genetic diversity. Therefore, genetic variability and diversity assessment are necessarily important for the foreign introduced materials. Experiment was conducted with 9 exotic sugarcane genotypes at Regional Station, Bangladesh Sugar Crop Research Institute, G...
