Ralstonia solanacearum species complex is a devastating phytopathogen with an unusually wide host range, and new host plants are continuously being discovered. In June 2016, a new bacterial wilt on Cucurbita maxima was observed in Guangdong province, China. Initially, in the adult plant stage, several leaves of each plant withered suddenly and drooped; the plant then wilted completely, and the ...

The mandarin horticultural group is an important component of world citrus production for the fresh fruit market. This group formerly classified as C. reticulata is highly polymorphic and recent molecular studies have suggested that numerous cultivated mandarins were introgressed by C. maxima (the pummelos). C. maxima and C. reticulata are also the ancestors of sweet and sour oranges, grapefrui...

The problem of locating local maxima and minima of a function from approximate measurement results is vital for many physical applications: In spectral analysis, chemical species are identiied by locating local maxima of the spectra. In radioastronomy, sources of celestial radio emission, and their subcomponents, are identiied by locating local maxima of the measured brightness of the radio sky...

Hybrid incompatibility and F1 hybrid dysgenesis in the interspecific hybridization between pumpkin (Cucurbita moschata Duch.) winter squash maxima have been previously noted. For this reason, it is difficult to obtain F2 generations due sterility. However, back-crossing add-crossing can be utilized overcome these barriers hybridization. To date, few studies focused on parental selection, proces...
