Barley scald, caused by Rhynchosporium commune is one of the most prevalent diseases in barley (Hordeum vulgare L.) worldwide. The primary loss from scald is reduced yield, which can exceed 25% in dry areas. In our earlier studies, we developed a low-resolution linkage map for recombinant inbred lines of the cross Tadmor/WI2291. Quantitative trait loci (QTLs) for scald were localized on chromosomes...
Eyespot is one of the most important fungal diseases of the stem base of wheat (Triticum aestivum L.). The presented study clearly demonstrated that the Pch1 gene was the main effective source for reducing the eyespot disease score in the analyzed winter wheat lines. Nevertheless, Pch1 was present only in 8−9% of the investigated lines. Using an isoenzymatic marker and molecular markers, the presence...
W 2009 roku w kolekcji Oddziału IHAR w Młochowie znajdowały się 54 diploidalne klony posiadające w swoim pochodzeniu źródła odporności na wirusy ziemniaka. Najważniejszymi gospodarczo wirusami atakującymi rośliny ziemniaka są PVY, PLRV, PVM, PVX i PVS. Źródłami odporności na wirusy ziemniaka są gatunki dzikie ziemniaka, S. stoloniferum (PVY), S. chacoense (PVY, PLRV), S. yungasense (PLRV), S. gourlayi...
Present challenges facing the pest management as a result of the Directive of European Parliament (2009/128/WE of 25th October 2009) and of Council established framework for Community action to achieve sustainable use of pesticides and obligatory implementation of required standards in Integrated Pest Management (IPM) start from 1st January 2014 in the EU member states. Critical analysis of present...
Rdza brunatna powodowana przez grzyb Puccinia recondita ROB. ex DESM f. sp. tritici ERIKS. et HENN. jest jedną z najgroźniejszych chorób pszenicy. Najskuteczniejszą metodą kontrolowania i ograniczania skutków porażenia przez choroby grzybowe, jest wprowadzenie do uprawy odmian z genetycznie uwarunkowaną odpornością. Celem badań była identyfikacja za pomocą markerów DNA (STS, SCAR) genów odporności...
Due to the deterioration in the health condition of Norway spruce on the IPTNS-IUFRO 1964/68 observation plots in Krynica (Poland), there was an urgent need to determine the cause of the decline in order to design preventive measures. For this purpose, a health inventory was carried out in the years 2002 and 2003. This included an assessment of the condition of crowns in 144 trees and a thorough examination...
