Tillers Diversity on One Hundred Accessions of Upland Rice Germplasm

Abstract

The utilization of local upland rice germplasm as genetic resources for important and potentially traits can be implemented if their characteristics have been known. Plant growth characters such as plant tillering will determine the levels of productivity of the plant. Tillering character has not been much characterized in most rice accession collected in BB Biogen genebank. The objective of this research was to characterize tillering type, including primary, secondary, and tertiary of 100 accessions of local upland rice. The Experiment was carried out by planting 100 local varieties of upland rice grown in pots with three replications in the greenhouse. The type of tiller that is marked with a string of different colors from early emergence was observed. Numbers of primary, secondary and tertiary tillers of the upland rice tested were observed at the age of two months and ripening stage. Grouping rice germplasm tested was implemented through average linkage cluster analysis method with Euclidean distance. The diversity of number tertiary tillers character at maturity stage was showed the highest diverse compared with other characters. Ketan Hitam and Ketan Salome are the two upland rice accessions that have the highest number of tillers.
