The production of fertile triploid hybrids from crosses between Hordeum vulgare L. (2n = 4x = 28) and H. bulbosum L. (2n = 2x=14)

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...

HORDEIN GENE DOSE EFFECTS IN TRIPLOID ENDOSPERM OF BARLEY (Hordeum vulgare L.)

مطالعه کاریوتیپی هفت گونه‌ جو (Hordeum) در استان فارس

A karyotypic study was performed on seven species of Hordeum Genus including, H. vulgare, H. spontaneum, H. glaucum, H. distichon, H. geniculatum , H. bulbosum and H. violaceum. According to the cytological studies in the laboratory, chromosome numbers and ploidy levels of species were identified. Chromosome analysese including the length of each chromosome, long and short arms length and long ...

Lysine Catabolism in Barley (Hordeum vulgare L.).

Lysine catabolism in seedlings of barley (Hordeum vulgare L. var. Emir) was studied by direct injection of the following tracers into the endosperm of the seedlings: aspartic acid-3-(14)C, 2-aminoadipic acid-1-(14)C, saccharopine-(14)C, 2,6-diaminopimelic acid-1-(7)-(14)C, and lysine-1-(14)C. Labeled saccharopine was formed only after the administration of either labeled 2,6-diaminopimelic acid...
