Efforts that can be made in dealing with the limiting factors of rice plants are developing local rice to get the desired character. The results of hybridization were selected to see the superior character of the offspring based on genetic parameters. The purpose of this study was to obtain the value of variability, heritability, and expected genetic advance in each 4th generation character [F 4 ]. Another goal was as a selection criterion for the 4th generation [F 4 ] line and to get a line of promising that can be used as the next generation of promising lines. The research activities were carried out in the Experimental Station of the Department of Agrotechnology, Faculty of Agriculture, Fisheries and Biology, Bangka Belitung University. This research employed an experimental method based on a single plant design with a single factor that was 56 4th generation [F 4 ] lines of crossed upland rice and 4 crossing elders. Qualitative characters were analyzed by calculating the modus of the characteristics of the whole population. Quantitative characters were analyzed by calculating variability, heritability, expected genetic advance, and t-student tests. The results showed that the character of flowering time, harvest time, and plant height had narrow variability, high heritability, and high expected genetic advance. The characters used for the selection criteria of rice plants in the 4th generation [F 4 ] were flowering time, harvest time, and plant height. As many as 70 lines were used as the next generation of promising lines [F 5 ].
