Characterization of Several Rice (Oryza sativa L.) Varieties as Germplasm

Abstract

Characterization of Rice plant (Oryza sativa L.) is required to obtain its potential or to eliminate unwanted characters for variety improvement. This research was conducted from September 2018 to April 2019. Non-factorial randomized block design (RBD) was used, with five varieties, namely ‘Landak’ (V1), ‘Inpari 24’ (V2), ‘Sintanur’ (V3), ‘Sidenuk’ (V4) and ‘Ciherang’ (V5). The characters observed were plant height, number of productive tillers, panicle length, flag leaf length, flowering age, harvesting age, number of grain, number of pithy grains, and yield potential. The data were analyzed using ANOVA and Tukey’s HSD test at 5%. The result showed that Ciherang belonged to the first group (≤ 20 tillers). Sidenuk, Sintanur, Inpari 24 belonged to the second group (21-30 tillers), and ‘Landak’ fell under the third group (> 36 tillers). For harvesting age, ‘Ciherang’ and ‘Sintanur’ were in the first group (≤120 days), ‘Sidenuk’ and ‘Inpari 24’ were in the second group (121-140 days), and ‘Landak’ come under the third group (> 140 days). For 1000 grain weight, three varieties resulted lower than their plant description: ‘Landak’ (20.26 g), ‘Ciherang’ (25.30 g), and ‘Sintanur’ (26.48 g), while ‘Inpari 24’ and ‘Sidenuk’ exceeded their plant description with 26.89 g and 26.06 g, respectively.
