Purification of local upland rice seeds based on morphological characteristics

Abstract This research is directed to overcome the problem of upland rice seeds that are no longer pure, because they have been mixed with other types seeds, which can result in a decrease quality or nature superior already favorable by community. Seed purification needed restore purity local lines. Another target this produce basic pure lines (without mixture), for further breeding programs, purpose releasing varieties, as well production purposes consumption. study aims select and detect same/uniform morphological characteristics each seed lot find out lots show high uniformity. The experiment used Randomized Block Design (RBD) consisting 20 treatment was made into so-called “ grid ” (replication) 3 grids. conducted at Field Laboratory, Experimental Garden II, Faculty Agriculture, Halu Oleo University. Observational data were analyzed variance qualitative characters converted binary NTSYS program. If there significant effect, then proceed Scott Knott group test (α = 0.05). results showed very effect on variables flowering age, productive tillers flag leaf angle, plant height, number leaves, tillers, harvest panicle length, area, total grain per percentage grain. panicle.
