Bean (Phaseolus vulgaris L.) is one of the main elements of the global food and especially of Brazil, which in turn has a privileged position in the market. Plant breeding has improved the production of the legume plants through research in the area and the introduction of new cultivars. The Value for Cultivation and Use (VCU) test is fundamental in proving the selection efficiency for registration and introduction of new cultivars in the market. The aim of the present study was to evaluate the performance and adaptability of twelve selected bean lines in relation to four control based on morphoagronomic traits, in the city of Pato Branco. The experiment was carried out on November 7, 2015 in the experimental area in the campus of UTFPR Pato Branco, meeting the minimum requirement established for the bean VCU assay, which consists of a randomized complete block design with three replications and plots of four rows with length of four meters each. The applied fertilization occurred with 200 kg ha-1, and 40 kg ha-1 of N in cover, in stage V3, during the crop cycle. Furthermore, insecticides were still applied when necessary, no application of fungicide was used to evaluate the resistance of the cultivars, the VCU does not use fungicides. In conclusion, it was verified that in spite of the differences in relation to the cycle and the mass of one thousand seeds of the selected bean lines, there was no statistical difference with respect to productivity by the Tukey test at a level of 5% of error probability. Thus, it is necessary to continue this test for another two years, in order to verify if some lineage differ statistically from the control in question so that the launching of the new cultivar is feasible. |
