Seed purity assessment of two local upland rice cultivars of Southeast Sulawesi based on agronomic characteristics

Abstract This research intended to purify upland rice seeds that have presumably been unintentionally mixed with various types of seeds, causing decreased quality or nature the superior cultivars. Seed purification effort is needed restore purity promising local The second long term goal this was produce basic pure are required for further breeding programs, and/or purpose releasing new varieties. study generation effort, aimed select same uniform agronomic characteristics cultivars in each seed lot. Similar first generation, experiment used a Randomized Block Design (RBD) consisting 15 lots as treatment and lot consisted 4 “ grids ” (replications). conducted at Field Laboratory, Experimental Garden II, Faculty Agriculture, Halu Oleo University. results showed several characters (i.e., plant height, leaf number, tiller number etc.) two were seem more compared purification. indicates gradually purer.
