A ®eld lysimeter study was conducted to investigate the effect of initial soil salinity and salinity level of brackish subirrigation water on tuber weight and tuber size of three potato (Solanum tuberosum L.) cultivars (Kennebec, Norland and Russet Burbank) under simulated arid conditions. Both saline and non-saline initial soil conditions were simulated in a total of 36 lysimeters. Eighteen ly...

BACKGROUND Plants selectively attract particular soil microorganisms, in particular consumers of root-excreted compounds. It is unclear to what extent cultivar type and/or growth stage affect this process. METHODOLOGY/PRINCIPAL FINDINGS DNA-based pyrosequencing was used to characterize the structure of bacterial communities in a field cropped with potato. The rhizospheres of six cultivars den...

Sweet potato, Ipomoea batatas (L.) Lam., is an important food and industrial material crop throughout the world. It is also an alternative source of bio-energy as a raw material for fuel production. China is the biggest sweet potato producer in the world. Biotechnology offers great potential for improving disease, pest and stress resistance and nutritional quality of sweet potato. In the past d...

Th e study was focused on evaluation of SUBSTOR – Potato model and its utilization in potato growing management in the Czech Republic. Th e experimental fi eld used for the model evaluation was located in Žabčice – South Moravia region with altitude of 179 meters above the sea level. Tuber yield served as reference for the model evaluation. Nine years experimental data set (1994 – 2002) was use...

The Sweet potato, Ipomoea batatas (L.) Lam, is difficult to study in genetics and genomics because it is a hexaploid. The sweet potato study not have been performed domestically or internationally. In this study was performed to construct genetic map and quantitative trait loci (QTL) analysis. A total of 245 EST-SSR markers were developed, and the map was constructed by using 210 of those marke...

The field experiment was carried out during 2004–2006. The aim of the study was to determine the influence of insecticides (Actara 25 WG – 0.08 kg/ha, Regent 200 SC – 0.1 L/ha, Calypso 480 SC – three rates: 0.05; 0.075; 0.1 L/ha), used for controlling Colorado potato beetle, on total glycoalkaloid (TGA) content in potato leaves and tubers of three cultivars (Mors, Wiking, Żagiel). The insectici...

Vitamin B6 is one of the most versatile cofactors in plants and an essential phytonutrient in the human diet that benefits a variety of human health aspects. Although biosynthesis of the vitamin has been well resolved in recent years, the main research is currently based on Arabidopsis thaliana with very little work done on major crop plants. Here we provide the first report on interactions and...

Present researcher was designed to evaluate the nutritional and antioxidant activity of the some prominent potato cultivars. The mean indicated that potato contained appreciable amount of moisture (77.5 to 82.37%), ash (1.46 to 1.66%), crude protein (2.037 to 3.062%), crude fat (1.16 to 1.89%) and crude fiber (2.12 to 2.66%). However, specific gravity were in the ranged of 1.05 to 1.22. The ant...

Potato cyst nematodes (PCN) collected in six localities in the Leningrad region of North West Russia were identified as Globodera rostochiensis pathotype Ro1 and were used for subsequent resistance tests. Seventynine accessions of cultivated and closely related wild potato species from the VIR collection in Russia were screened on resistance to G. rostochiensis pathotype Ro1 and on the presence...
