Resistance of potato germplasm to the potato tuberworm (Lepidoptera: Gelechiidae).
The evaluation of potato germplasm for resistance to potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is a valuable component of integrated pest management; however, few attempts have been made to identify natural genetic tuber resistance to tuberworm on potato germplasm. The objective of this study was to screen potato germplasm with potential tuberworm resistance...

abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
Induction of Resistance to Potato Virus Y (PVY) Using Hairpin Construct of Coat Protein
Potato virus Y (PVY) is one of the most damaging viruses of potato plants which infecting most cultivars and causing significant yield and economical losses. The application of the concept of pathogen derived resistance opened new horizons for the development of virus-resistant plants. This research was carried out to study RNA silencing to engineered potato plants that are resistant to potato ...
متن کاملCombining genetic engineering and traditional breeding to provide elevated resistance in potatoes to Colorado potato beetle
The sustainable deployment of resistant crop varieties is a critical issue for the implementation of biotechnology in crop pest management. Feeding, biomass accumulation, and mortality were evaluated for susceptible, insecticide-resistant, and Bacillus thuringiensis (Bt) Cry 3A-selected Colorado potato beetle ( Leptinotarsa decemlineata Say) (Coleoptera, Chrysomelidae) larvae fed on: cultivated...
متن کاملResistance in Potato to Pratylenchus penetrans.
Potato clones from five different breeding populations were evaluated for their relative resistance and susceptibility to Pratylenchus penetrans. Resistance and susceptibility were distinguished by an index of susceptibility (SI) calculated from the numbers of P. penetrans (including eggs) per g of root of individual clones in relation to that of a susceptible control at 30 or 70 days after ino...
