Abstract:
The purpose of this study was to identify the species of local landraces of wheat (Triticum spp.), held in the Israel Gene Bank, to evaluate them for basic characters and to assess their response to infection by two rust fungi under artificial inoculation conditions. One-hundred-thirty one seed samples were collected from local or Beduin farmers during 1978-1981 throughout the Galilee, Mt. Gilboa. Judean Desert and the south Negev. The samples were collected and stored in the Israel Gene Bank without any characterization or evaluation. Each accession was planted in a 1 m row at Bet Dagan and grown under favorable conditions for plant growth and rust development. Determination of the species, data of plant height, days to heading and reaction of the landraces to artificial inoculation with a composite inoculum of Puccinia recondita and P. striiformis were collected from each row. A small part of the landraces collection consisted of mixed populations of T. durum and T. aestivum plants, where one of the two species was predominant. One-hundred-fourteen and 17 accessions from this collection represented, respectively, Triticum durum and T. aestivum Israel landraces. Large variations were found for all the characters examined. Of the total accessions, 6.5% (8 accessions) and 32% (42 accessions) were resistant, respectively, to yellow- and leaf-rust. It was concluded that the diversified populations of the local landraces of wheat can be used as a source not only for genes affecting basic characters such as plant height and heading date, but also for resistance to leaf rust and yellow rust.
