Em. Karlssonstrese et al., STRATEGY FOR CATCH CROP DEVELOPMENT .1. HYPOTHETICAL IDEOTYPE AND SCREENING OF SPECIES, Acta agriculturae Scandinavica. Section B, Soil and plant science, 46(2), 1996, pp. 106-111
Hypothetical criteria were defined for a catch crop insown in spring c
ereals with the main purpose of reducing leaching of nitrogen. The cri
teria were applied in the screening of a large variable plant material
from three groups: Poaceae, Fabaceae and species from other families.
Variation in the characters of interest between and within species wa
s recorded in spaced field plantings. Perennial species adapted to the
Nordic climate possessed many of the characteristics expected to be d
esirable. Accessions expected to have a potential as catch crops were
identified in all three groups. The group ''other families'' is of gre
at interest. The most interesting species for further experiments were
Cichorium intybus, biennial species in Brassicaceae, Lotus corniculat
us, Trifolium fragiferum and Lolium spp.
