A collection of introduced legumes was grown first in the quarantine glasshouse and later
in a spaced-plant experiment in the field. Morphological and performance data were recor-
ded in each case, and separate classification erected and compared. The first compari-
son used only agronomic-type data, omitting all information normally obtained from herba-
rium specimens; the classifications were nevertheles in substantial agreement. "Plasticity"
characters, representing differences brtween glasshouse and field measurements, were
found useful. Finally, data from the herbarium material were added and classification again
compared. The glsshouse groupoing now corresponded very closely with those from the field and were even in some respects preferable. This suggests that conventional spaced-
plant trials could be reduced or even omitted, material for more advanced testing being
selected on the basis of the glasshouse description and knowledge of the background
ecology of the accession. It would be essential that such description were published to
enable their inclusion in data-banks of genetic resources. |
