dc.description	The objective of this research was to evaluate the linear relations among pigeon pea (Cajanus cajan (L.) Millsp.), cultivar BRS Mandarim, traits and identify the ones applied for indirect selection. Two uniformity experiments were carried out, in an experimental area located 29º42’S, 53º49’W and with 95m of altitude, selecting 360 plants per experiment, totaling 720 plants. For each plant, the number of nodes was counted and the height and stem diameter were measured, for ten evaluation times (62, 69, 76, 83, 90, 98, 104, 111, 119 and 125 days after sowing - DAS) in the first experiment and 18 times (44, 51, 58, 65, 72, 79, 86, 93, 100, 107, 114, 120, 128, 135, 141, 148, 156 and 162 DAS) in the second experiment. During plant flowering, i.e. the 125 DAS in the first experiment and 162 DAS in the second experiment, the fresh and dry mass for each plant was obtained. The sigmoidal model was adjusted and it was studied the relations among the traits through correlation and path analysis. In the pigeon pea crop, the stem diameter has a positive and linear relation with the fresh and dry mass and it can be used for indirect selection.	en-US
