Katuray (Sesbania grandiflora L.) is an underutilize leguminous crop that contributes significantly to national food security and the livelihoods of small-scale farmers in the
developing world. Despite its potential economic significance, it has not been fully known
in La Union due to a lack of information on the genetic background of the cultivated
landraces. Therefore, the main objective of this study was to evaluate morphological
diversity and geographical mapping of 40 katuray accessions in La Union province using
morphological characters. A total of 15 qualitative traits and 13 quantitative traits were
assessed. The qualitative traits showed intermediate diversity with an average diversity
index of H’=0.39, whereas quantitative traits has an average diversity index of H’=0.63
which indicates that there is a high diversity in terms of quantitative traits which means
qualitative traits are less diverse than quantitative traits. Unweighted pair group method
with arithmetic mean (UPGMA) generated a dendrogram that distinctly grouped the 40
katuray accessions into six major clusters based on qualitative and quantitative
morphological traits. Unique characteristics was also determined, namely; red and pink
color of flower, and black in seed colour. Katuray's geographical mapp alo showed that
out of 40 accessios, there are 47.5% white flowers were mainly found in the different
municipalities of La Union province followed by red flowers with 37.5%. The preliminary
results of this study revealed that katuray accessions in La Union province are diverse.
