Abstract Information on the genetic diversity of wild rice species in Sri Lanka is relatively meagre, though it plays a key role
in crop improvement programs of cultivated rice (Oryza sativa L.). The present study was carried out to identify
the morphological variation pattern of the wild populations of O. nivara in Sri Lanka. Seven populations (P1 to
P7) collected from different agro-ecological regions were characterized in a common garden based on nine morphological traits. The findings revealed a high level of phenotypic variation between populations when compared
to within a population. The most variable traits were the flag leaf panicle… More >
