The aim of this study was to evaluate the tolerance of sunflower (Helianthus annuus) to acetolactate synthase (ALS)-inhibiting herbicides and to temporarily delay the growth of Brachiaria ruziziensis, avoiding competition and allowing pasture reestablishment. Experiment 1 consisted of a randomized complete block design, with four replicates. Hybrid Paraiso 102 CL (Clearfield®, resistant to ALS-inhibiting herbicides) was a subject of the following treatments: I) 30 g ai ha-1 imazethapyr; II) 70 g ai ha-1 imazethapyr; III) 75 g ai ha-1 imazapyr; IV) 125 g ai ha-1 imazapyr; V) 7.5 g ai ha-1 chlorimuron-ethyl; VI) 12.5 g ai ha-1 chlorimuron-ethyl; VII) 8 g ai ha-1 nicosulfuron; VIII) 20 g ai ha-1 nicosulfuron; IX) unhoed check and X) hoed check. Experiment 2 consisted of a split-plot design with randomized complete blocks and four replicates. Two genotypes, Paraiso 102 CL and Embrapa 122 (susceptible to ALS-inhibiting herbicides), were sowed on the plots and subplots were submitted to the following treatments: I) hoed check, II) unhoed check, III) 100 g ai ha-1 imazethapyr, IV) 250 g ai ha-1 imazapyr, V) 25 g ai ha-1 imazapyr, VI) 60 g ai ha-1 nicosulfuron, and VII) 4 g ai ha-1 nicosulfuron. Imazethapyr (30, 70 and 100 g ai ha-1), imazapyr (25, 75 and 125 g ai ha-1) or nicosulfuron (4, 8 and 20 g ai ha-1) had no phytotoxic effects on imidazolinone-resistant sunflower (Paraiso 102 CL). However, chlorimuron-ethyl (7.5 and 12.5 g ai ha-1), imazapyr (250 g ai ha-1) and nicosulfuron (60 g ai ha-1) were highly phytotoxic to Paraiso 102 CL. All herbicide treatments produced marked injury symptoms on Embrapa 122. Pasture reestablishment was observed for all herbicide treatments, except for imazapyr (125 and 250 g ai ha-1) and nicosulfuron (60 g ai ha-1).

The aim of this work was to estimate the adaptability and stability of grain yield per hectare and percentage of crude protein of maize grains combined in an index, and to establish a multicharacter selection through mixed models based on an objective character and 15 auxiliary traits. The trials were conducted in the 2013/2014 agricultural year in four growing environments of the Rio Grande do Sul, BR state. The experimental design was randomized blocks arranged in a factorial scheme, being four growing sites × 15 single cross maize hybrids, arranged in three repetitions. The genotypic index, composed by the grain yield and the crude protein percentage in the grains, is the best selection strategy to achieve maize superior genotypes. The multivariate genotypes selection, considering grain yield and crude protein, is efficient. The genotypes FORMULA TL®, AS1656PRO®, P30F53Hx®, LG6304YG® and 30F53 are more adapted and stable for grain yield and percentage of crude protein, in the conditions of this study. The mixed models were efficient to employ the multicharacter selection and to contribute for maize genetic breeding. |
