Abstract:
Crop improvement relies on understanding the morphological variation and population structure of germplasm collections. Because of the importance of rice (Oryza sativa L.) as a major world crop, the origin and diversity of this plant have piqued the curiosity of many people. In this study, A total of 107 aromatic rice lines were classified using five quantitative traits. The rice germplasm contains adequate genetic variation for most of the quantitative traits. Yield per plant had significant association with total tiller number and other traits had positive association with each other except with panicle length. Cluster analysis produces three groups. PCA also show considerable diversity among the genotypes. The characterization of landraces of aromatic rice would provide significant benefits to breeders in their efforts to design and implement further rice improvement programmes.
