Abstract

The effectiveness and successful of selection depend on the value of genetic variability, heritability and genetic advance estimation. The purpose of this research is to measure the value of genetic parameters (variability, heritability and genetic advance) of F2 lines derived from crossing of mutant red rice, local accession of red rice, and commercial upland rice varieties. This research used single plant design. The rice materials used in this research was the F2 seeds derived from hibridization between MR1512 X Inpago 8, MR1512 X Banyuasin, Inpago 8 X Balok, Balok X Banyuasin and Balok X Inpago 8. Selection intensity used is 10%. The filled grains and grain weight have a wide phenotypic variability, whereas the plant height and the productive tiller numbers have wide genotypic variability. The high heritability value was found in the plant height, flowering time, and harvest time. The high genetic advance was found in plant height, productive tillers number, flowering time, and harvest time. In the present work, it has been shown that the plant height, productive tiller numbers, flowering time, and harvest time are the important traits for use in rice lodging tolerance breeding program.
