Description Increasing population and limited arable lands has perpetuated the efforts to improve yield per unit area through various methods such as sophisticated agronomical operations, selection of productive and tolerant genotypes and improving germination components. In order to study genetic diversity of 22 rice (Oryza sativa L.) landraces native to northern part of the country in terms of germination components and of some growth indices, an experiment was conducted at laboratory of agriculture faculty of Islamic Azad University, Ardabil branch, as randomized complete blocks design with three replications, in year 2011. Estimation of phenotypic and genotypic coefficients for various traits revealed that genotypes being studied were more genetically diverse in terms of FGP, GI, GRI, Rs, VI, seedling length, radicle length and total fresh weight of sample than in terms of other traits. Study genotypes were classified into four groups using cluster analysis. Mean squares between the groups were significant for all the traits except for ratio of radicle length to seedling length. Germination indices were more heritable than traits associated with growth indices. Results from cluster analysis showed that group 2 including genotypes numbered 2, 16, 5, 14, 22 and 6, had the highest values for all the traits and was in average status in terms of traits such as MGT, Rs, MDG and ratio of radicle length to seedling length and consequently was recognized as the best group.
