The resistance to leaf rust and powdery mildew of recombinant lines of barley (Hordeum vulgare L.) derived from H. vulgare · H. bulbosum crosses
A set of 23 recombinant lines (RLs) of barley (Hordeum vulgare L.) derived from H. vulgare · H. bulbosum L. crosses was inoculated with barley leaf rust (Puccinia hordei) and powdery mildew (Blumeria graminis f.sp. hordei) at the seedling stage to identify their levels and mechanisms of resistance. Eight RLs were studied further in glasshouse and field tests. All three barley parents ( Emir , G...
متن کاملPLANT REGENERATION FROM IMMATURE EMBRYO-DERIVED CALLUS OF BARLEY (Hordeum vulgare L.): EFFECT OF AUXINS AND CYTOKININS
Embryogenic callus was induced from culturing immature embryos of three barley cvs. Dissa, Golden Promise and Igri. Maximum embryogenic callus formation was achieved by culturing immature embryos on CC and LS medium containing 2 mg/litre and 2.5 mg/litre 2,4dichlorophenoxyacetic acid (2,4-D) respectively. Embryogenic calli were frequently produced distinguished somatic embryos on these medium. ...
متن کاملDifferent Salts Effects on the Germination of Hordeum vulgare and Hordeum bulbosum
The germination responses of Hordeum ulgare seeds to saline stress caused by different salt types was studied. For this, 25 seeds of mentioned species were placed on filter paper in Petri dishes containing distilled water (control), 60, 120, 180, 240, 300, 360 and 420 mM. saline solution of NaCl, CaCl2 an KCl. The results indicated that saline levels effects were significant (P < 0.05) for seed...
متن کاملGenetic Control of Chromosome Elimination during Haploid Formation in Barley.
Genetic control over chromosome stability in the interspecific hybrid embryos of Hordeum vulgare and H. bulbosum has been hypothesized to reside on specific chromosomes. In this study, crosses between the primary trisomic lines for the seven different H. vulgare chromosomes and tetraploid H. bulbosum revealed that both chromosomes 2 and 3 of H. vulgare were involved in the control of chromosome...
متن کاملMature embryo axis-based high frequency somatic embryogenesis and plant regeneration from multiple cultivars of barley (Hordeum vulgare L.).
A highly reproducible regeneration system through somatic embryogenesis from the excised mature embryos (MEs) of dry seeds of a range of European barley cultivars was developed. By minimizing the germination of plated MEs, primary callus could be obtained with high frequency which permitted efficient embryogenesis and regeneration of a large number of green plants. Different approaches were tes...
