Summary

An old hybrid population of the interspecific cross Hordeum laevigatum x Goudgerst was chosen as initial material on a selection basis in 1947. We succeeded in raising the mildew-resistant fodder barley varieties Minerva and Vada which are also suitable for the production of pearled barley.

It is remarkable that without backcrossing from this interspecific crossing, varieties have been obtained with such a high production capacity. Crosses of Hordeum laevigatum with other barley varieties, excelling Goudgerst in production, may lead to even better results.

Samenvatting

Een oude kruisingspopulatie van de soortskruising Hordeum laevigatum × Goudgerst werd in 1947 gekozen als uitgangsmateriall voor de zomergerstveredeling. Het gelukte ons hieruit de meeldauwresistente voergerstrassen Minerva en Vada te kweken, die tevens geschikt zijn voor de gortbereiding.

Het is vermeldenswaard dat zonder terugkruising toe te passen uit deze soorts-kruising rassen zijn verkregen met zulk een hoog opbrengstvermogen. Wellicht zullen kruisingen van Hordeum laevigatum met andere gerstrassen, die Goudgerst in opbrengstvermogen overtreffen, tot nog gunstiger resultaten leiden.
