| dc.description | The direct and relative contribution of characters associated with forage production were evaluated in a comparative assay of wheat cultivars to contribute to an ideotype defnition when selecting double purpose material for forage and grain production. Simple correlations for all of the possible combinations among the measured variables were calculated. The correlation partition method, known as path coeffcient, was applied to determine the causes of this association and to measure the relative importance of each factor. Forage production during the vegetative period was measured for each variety at the dates in which the apex reached the double ridge state (3 - 4 in the Nerson scale). The double ridge state was considered the deadline of the vegetative primordial production. Tiller numbers, live leaf numbers, dead leaf numbers, total leaf numbers and yield components in the forage were measured simultaneously. These variables had values of correlation, high positive and signifcant (p ≤ 0.01) with variable dry weight, and largely explained (R ² = 0.963) forage yields of the cultivars. Standard partial regression analyses indicated that the variables that most contributed to forage production were the total leaf and tiller number. Under these criteria, the ProINTA Pincen and ProINTA Super cultivars that had the highest dry weight values should meet the required conditions to adapt to dual purpose production. | |
