Нашими попередніми дослідженнями встановлена висока стійкість окремих зразків H. spontaneum до популяцій рас гельмінтоспоріозної інфекції південної зони України та характер успадковування цієї стійкості у гібридних поколіннях [8, 9] при цьому використання джерел патогенів в селекції рослин це імунологічний напрям, тоді як звичайний селекційний процес охоплює відразу кілька напрямків оцінювання ...

Informed collecting, conservation, monitoring and utilization of genetic diversity requires knowledge of the distribution and structure of the variation occurring in a species. Hordeum vulgare subsp. spontaneum (K. Koch) Thell., a primary wild relative of barley, is an important source of genetic diversity for barley improvement and co-occurs with the domesticate within the center of origin. We...

BACKGROUND All plants in nature harbor a diverse community of rhizosphere bacteria which can affect the plant growth. Our samples are isolated from the rhizosphere of wild barley Hordeum spontaneum at the Evolution Canyon ('EC'), Israel. The bacteria which have been living in close relationship with the plant root under the stressful conditions over millennia are likely to have developed strate...

A new cytoplasmic male sterility in barley (Hordeum vulgare s.l.) is described and designated as msm2. The cytoplasm was derived from a selection of the wild progenitor of barley (H. vulgare ssp. spontaneum). This selection, 79BS14-3, originates from the Southern Coastal Plain of Israel. The selection 79BS14-3 has a normal spike fertility in Finland. When 79BS14-3 was crossed by cv. Adorra, the...

The association of alleles among different loci was studied in natural populations of Hordeum spontaneum, the evolutionary progenitor of cultivated barley. The variance of the number of heterozygous loci in two randomly chosen gametes affords a useful measure of such association. The behavior of this statistic in several particular models is described. Generally, linkage (gametic phase) disequi...

Wild barley (Hordeum spontaneum K.) and indigenous primitive varieties of cultivated barley (Hordeum vulgare L.), collected from 43 locations in four eastern Mediterranean countries, Jordan, Syria, Turkey and Greece, were electrophoretically assayed for genetic diversity at 16 isozyme loci. Contrary to a common impression, cultivated barley populations were found to maintain a level of diversit...

In normal growth conditions, total protein percent (salt soluble plus hordein fractions) in the endosperm at maturity in barley cultivar Hordeum vulgare L. cv ;Ruth' was about 14%, whereas in an accession of wild barley, Hordeum spontaneum Koch line 297, it was about 28%. Spike culture experiments were conducted to ascertain whether there were basic differences between the two genotypes under c...
