【 摘 要 】

It is important to study the linear relations among characters for indirect selection of plants. The objective of this paper was to evaluate the linear relations among characters of black oat (Avena strigosa Schreb) and identify characters for indirect selection. Field experiment was conducted and in ten evaluation times (22, 28, 34, 42, 48, 55, 76, 83, 90 and 105 days after sowing) were randomly selected 52 plants, totaling 520 plants. In each plant, were measured the characters plant height, number of leaves and number of tillers, and fresh and dry masses. The sigmoidal model was adjusted and it was studied the relations among the traits by correlation and path analysis. In the culture of black oat, the number of leaves per plant and plant height has a positive linear relation with the fresh and dry masses of shoots and can be used for indirect selection.
