RELATIONSHIP BETWEEN MORPHOLOGICAL VARIATION AND GEOGRAPHICAL ORIGIN OR SELECTION HISTORY IN LUPINUS-PILOSUS

Patterns of morphological diversity were examined in Lupinus pilosus i n relation to geographical origins or selection history of accessions. There was significant variation among accessions For most architectur al and reproductive characters in a Field experiment in Perth, Western Australia. Late flowering was associated with rosetted early growth. profuse branching and collection in higher rainfall sires. High yield and profuse podding on the main stem was associated with large pods an d leaves, many seeds per pod, greater height to the first main-stem po d, and collection in higher altitude sites. Ten groups of accessions, identified by hierarchical cluster analysis, accounted For 79% of geno type and 69% of genotype x character sums of squares. One group, possi bly taxonomically distinct from the others, consisted exclusively of w ild types from northern Israel with poor pod set and low seed yield, p oor nodulation, pale foliage, and small leaves. Wild types from Turkey and Crete had rosetted early growth and were late flowering. and the Turkish group had extremely rapid mid-season growth. Ornamental types from Europe or Australia with pink. purple or white flowers clustered together in an early flowering group with vigorous early growth. A smo oth-seeded type of L. pilosus was discovered in a group of short, late flowering and rough-seeded types from Syria.
