Identification of Aegilops germplasm with multiple aphid resistance
Original language description
The greenbug, Schizaphis graminum, (Rondani), the Russian wheat aphid, Diuraphis noxia (Mordvilko), and the bird cherry oat aphid, Rhopalosiphum padi (L.), cause several million dollars worth of wheat production losses annually in Europe and the United States. In this study, Triticum and Aegilops accessions from the Czech Research Institute of Crop Protection and the Kansas State University Wheat Genetic Resources Center were evaluated for resistance to these aphids. Accessions with aphid cross-resistance were examined for expression of the antibiosis, antixenosis, and tolerance categories of resistance. Aegilops neglecta accession 8052 exhibited antibiotic effects toward all three aphids in the form of reduced intrinsic rate of increase (rm). The rm of greenbug (biotype I) on Ae. neglecta 8052 was significantly lower than that of greenbugs on plants of the susceptible U. S. variety Thunderbird. The rm of Russian wheat aphids was significantly lower on foliage of both Ae. neglecta 8052

Identification genetických zdrojů Aegilops s kombinovanou resistencí vůči mšicím
Czech description
Mšice Schizaphis graminum, (Rondani), Diuraphis noxia (Mordvilko) a Rhopalosiphum padi (L.) způsobují milionové škody na pšenici. GZ Triticum a Aegilops z genové banky VURV a Kansas State University Wheat Genetic Resources Center byly hodnoceny na resistenci k těmto mšicím. Plané GZ s kombinovanou resistencí byly testovány na projev antibiosy, antixenosy a tolerance Aegilops neglecta č 8052 vykázal antibiotické efekty vůči třem sledovaným mšicím. Předběžné výsledky ukazují, že T. araraticum 168 může nést toleranci k RP. Nové geny z Ae. neglecta a T. araraticum vykazující antibiosu mohou být využity k vyvinutí pšenic s kombinovanou resistencí.
