Resumo: Grain productivities of 100 bean lines were evaluated in the presence and absence of nitrogen fertilizer in order to identify those with high nitrogen use efficiency (NUE) and to determine the correlated response observed in a stressed environment following selection in a non-stressed environment. The genetic and phenotypic characteristics of the lines, as wellas the response index to applied nitrogen, were determined. The average grain productivities at both locations were 39.5% higher in the presence of nitrogen fertilizer, with 8.3 kg of grain being produced per kg of nitrogen applied. NUE varied greatly between lines. Lines BP-16, CVII-85-11, BP-24, Ouro Negro and MA-IV-15-203 were the most efficient and responsive. The results showed that it is possible to select bean lines in stressed and non-stressed environments. It was inferred that common bean lines for environments with low nitrogenav ailability should preferably be selected under nitrogen stress.

Estimaram-se os índices deresposta à aplicação de nitrogênio e os parâmetros genéticos e fenotípicos. Namédia dos locais, a produtividade de grãos obtida com N foi 39, 5% acima daobtida sem N, correspondendo a 8, 3 kg de grãos por kg de N aplicado. A EUNvariou entre as linhagens. As linhagens BP-16, CVII-85-11, BP-24, Ouro Negro eMA-IV-15-203 foram as mais eficientes e responsivas. É possível obter sucessocom a seleção em ambientes com e sem estresse de nitrogênio, contudo a seleçãode linhagens para ambientes sob baixa disponibilidade de nitrogênio deve serrealizada preferencialmente nesta condição.Universidade Federal de Viçosa2020-11-04T20:05:48Z2020-11-04T20:05:48Z2014-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFURTINI, I.
