Abstract:
Rice is staple food for more than half of the world’s population and a new flagship crop to ensure food security for Ethiopians. This research was conducted with the aim of quantifying the extent of phenotypic and genotypic variability, and estimating broad sense heritability and genetic advance among 100 rice genotypes in Northwestern Ethiopia. The experimental design was triple lattice design which laid out with 10×10 in 2021/22 main cropping season. Analysis of variance indicated high significant (Pct selection. Accordingly, to improve panicle length G18 and G68, thousand grain weight G21 and days to 50% heading G57 and G87 are recommended donor rice genotypes for future crossing works.
