Correlation and path analysis in wheat cultivars in the initial period of development

The cultivation of soybeans in the central region state Rio Grande do Sul, has increased interest farmers for winter crops region. However, information related to crop development a low-latitude environment is limited and necessary improve management. objectives this article were evaluate linear relation between traits spring wheat cultivars initial period low-altitude site. experiments conducted two years Santa Maria - RS. experimental design used was randomized blocks, with ten cultivars. evaluations carried out at end tillering, where 300 plants selected per year, obtaining total sample number 600 plants. After selecting, character’s plant height (PH), leaves main stem (NLMS), (NLP), tillers (NT), dry matter (DM) measured. Pearson’s correlation coefficient matrices estimated, path analysis variable DM performed as function PH, NLMS, NLP, NT, DM. TBIO Mestre Sinuelo have higher tillers. NLP greater direct effect on DM, field conditions it recommended count relationship associated this, character fast agronomic value crop. In site, depends environmental conditions. high tillering capacity. Based relationships, through non-destructive selection tillers, mass are indirectly selected. because quick measure.
