Desempenho agronômico de variedades de trigo no sudoeste do Paraná na safra 2016

Abstract

O Taestivum accounts for more than 75% of world production. In Brazil, wheat stands out in the states of PR and RS with more than 500 thousand / ton. The objective of this study was to evaluate the productive potential of ten wheat varieties recommended for the southwest of the state of Paraná, seeking to define which one is more prominent in this criterion, in order to contribute with more assertive recommendations at the regional level so that farmers are able to obtain larger productivities. The wheat varieties tested in the experiment were: BRS Sabiá, IPR Catuara, FPS Certero, TBIO Sossego, TBIO Sinuelo, TBIO Toruk, ORS Vintecinco, ORS 1403, ORS 1401, CD 1104, chosen according to their indication by the breeder for the region of the study. The population of plants was standardized, 330 m² plants. At the harvesting point of the cultivars, approximately 130 days, the manual collections of the plots were evaluated for grain yield. In addition, 5 plants were sampled to evaluate the number of panicles, number of grains per panicle and mass of one thousand grains (grams). Data were submitted to anova and compared by the Duncan Test. The genotypes IPR Catuara, FPS Certero, TBIO Sinuelo, ORS Vintecinco and CD1104 did not differ on the number of panicles in the spikelets, and can be considered the best for this character. For the number of grains, only TBIO Toruk differed statistically from the others, which was lower. The genotype IPR Catuara presented the highest weight average of one thousand seeds, being this statistically superior to the others. The yield of grains is the most important character for the wheat crop. This character showed a high average and low CV%, demonstrating that the experimental precision was high. For this character, genotype CD 1104 was superior to the others. Thus, evaluating the conditions and characteristics presented the cultivar that stood out was CD 1104 with pH of 85.3, 15.2 panicles per spike and 36.1 grains per spike, which explains the productivity of 9,669.02Kg ha-1, being the best option among the varieties tested for recommendation to farmers.
