Abstrakt: Rice is the staple food among the Indonesian population. Plant breeding programs in self-pollinated crops like rice, improve genotypic and phenotypic variance, and also made significant enhancement of economic characteristics. The selection of rice genotypes based on high genetic variability would be an effective method. The experimental materials consisted of 12 Oryza sativa L. cultivars from Central Java. The study aimed to obtain information on rice genetic parameters of 22 agronomical characteristics. The results of the present study showed significant differences among rice genotypes. Especially on 3 qualitative characters and 12 quantitative traits. The presence of a more increased genotypic coefficient of variation than the phenotypic revealed the negligible influence of the environment on the expression of rice characters. High heritability was observed in rice leaf width, panicle length, and the number of grains per panicle. A better insight into genetic diversity and the heritability of rice characters in the breeding process can help improve rice grades. [ABSTRACT FROM AUTHOR]
