BERED, Fernanda et al. Characterization of wheat germplasm through the cycle and height adaptive characters. Pesq. agropec. bras. [online]. 2002, vol.37, n.2, pp.145-150. ISSN 0100-204X.

Identification of genetic variability is crucial in any breeding program. The knowledge of genotypes helps the breeder in planning crosses aiming to increase genetic variance. The objective of this study was to identify and cluster useful wheat germplasm through the adaptive characters heading date and plant height. Fifty-three wheat genotypes which revealed a significant decrease of both characters in the last years were evaluated. The dendrogram clustered five groups composed mainly of cultivars of the same era of release.

Keywords : Triticum aestivum; genotypes; genetic variation; breeding methods.
