“…Produtividades médias acima de 20 Mg ha -1 de vagens são consideradas altas para cultivares de feijão-devagem de hábito indeterminado (OLIVEIRA et al, 2003), portanto, estes mesmos autores atingiram produtividades máximas de até 29 Mg ha -1 para esta cultura, no Estado da Paraíba. Peixoto et al (2002) estudando a adaptabilidade e estabilidade de 15 genótipos de feijão-de-vagem de crescimento indeterminado, em oito ambientes, obtiveram produtividades de 8,09 Mg ha -1 (menor produtividade) até genótipos com 35,7 Mg ha -1 d e v a gens (maior produtividade).…”

“…Outros autores também encontraram teores de fibras nesta fabácea dentro destes padrões (ARAÚJO, 2000;OLIVEIRA et al, 2001;OLIVEIRA et al, 2003), conforme estabelecido por Peixoto et al (1993) Entretanto, na literatura existem resultados cujos teores de fibras nas vagens de feijão-de-vagem são bem mais elevados, dependendo da metodologia de extração empregada e do ponto de colheita das vagens. Oliveira et al (2001) encontraram teores da ordem de 20% de fibra bruta em vagens secas de feijão-de-vagem.…”

Resumo -O feijão-de-vagem é uma hortaliça rica em fibras, proteínas e vitaminas. Dentro do programa de melhoramento do feijão-de-vagem da Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF), foram realizadas seleções nas populações F 2 , em campo; avançando até F 5 pelo método SSD, em casa de vegetação; selecionando 30 linhas promissoras em F 6 . Continuando o programa, a geração F 7 foi cultivada e avaliada, em campo, em Campos dos Goytacazes e em Bom Jesus do Itabapoana. As características avaliadas foram: altura de inserção da primeira vagem (APV); altura da planta (AP); o número médio de vagens por planta (NMV); comprimento médio das vagens (CMV); peso médio de grãos por vagem (PMGV); teor de fibras nas vagens (FIB); produtividade de vagens por hectare (ProdVagens) e a produtividade de grãos por hectare (ProdGrãos). Não houve interação genótipo x ambiente (local) para a característica teor de fibra nas vagens, indicando ser esta bastante estável aos ambientes estudados. O teste de Scott-Knot formou três grupos quanto ao teor de fibras nas vagens frescas. Houve efeito significativo de genótipos para todas as características avaliadas, exceto para o NMVP. Os acessos UENF 7-20-1, UENF 7-5-1, UENF 14-22-3, UENF 15-8-4, UENF 1445, Top seed blue line, Feltrin, UENF 14-16-3, UENF 7-10-1, UENF 14-6-3 e UENF 15-23-4 foram respectivamente os mais produtivos, com rendimentos de 20.052 a 15.873 Mg ha -1 de vagens e na produção de grãos (2.693 a 2.014 Mg ha -1 ). A característica mais correlacionada com os rendimentos de vagens e de grãos foi o NMVP seguido por CMV. Palavras-chave -Feijão-de-Vagem. Caracteres agronômicos.

Within of the breeding program of snap bean of Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF), selections were performed in F2 populations in the field, advancing to F5 by SSD method, in a greenhouse, selecting 30 promising lines in F6. Continuing the program, the F7 generation was cultivated and evaluated in the field in Campos dos Goytacazes and in Bom Jesus do Itabapoana. The characteristics evaluated were height of first pod insertion (APV), height of plants (AP), average number of pods per plant (NMV); average length of pods (CMV), average weight of grains per pod (PMGV); fiber content in pod (FIB), pod productivity per hectare (ProdVagens) and grains productivity per hectare (ProdGrãos). There has no interaction genotype x environment (local) for the characteristic fiber content in pod, indicating that this is very stable environments studied. The Scott-Knot test formed three groups as to fiber content in fresh pods. There was significative effect of genotypes for all characteristics considered, except for the NMVP. The accesses UENF 7-20-1, UENF 7-5-1, UENF 14-22-3, UENF 15-8-4, UENF 1445, Top seed blue line, Feltrin, UENF 14-16-3, UENF 7-10-1, UENF 14-6-3 and UENF 15-23-4 were respectively the most productive, with yields from 20,052 to 15,873 Mg ha -1 of pods and in gra...

“…For snap bean crop, there is a huge absence of information in Brazilian literature related to these nitrogen fertilization aspects and the few studies performed were mainly with indeterminate growth habit cultivars (OLIVEIRA et al, 2003). Therefore, the aim of this study was to evaluate the nitrogen nutrition and the productive performance of determinate growth habit snap bean plants as a function of N sources and rates.…”

Snap bean is a vegetable crop presenting high requirements of mineral nutrients, such as nitrogen (N). However, studies on the response of this crop to N fertilizationare scarce, mainly with determinate growth habit genotypes, making it difficult to manage thisnutrient supply. The aim of this study was to evaluate the nitrogen nutrition and the productive performance of snap bean withdeterminate growth habit as a function of N sources and rates. The experiment was carried out inpots, under greenhouse conditions, inaEutrophicRed Oxisolwith 36.60 g dm-3of soil organic matter content.The cultivar ‘Macarrãorasteiro’TopSeedwas grownin a completely randomized design at factorial scheme 3x4, with four replications. It was studied three sources of N (urea, ammonium sulfate and sulfammo) and four rates (0, 40, 80 and 120 kg N ha-1), applied20% at sowing time, 40% at 12 days after emergence (DAE) and 40% at 20 DAE.It was evaluatedthe N content of the index leafandtheNaccumulationinshoots, the plant height at the endof the cycle and the number, total fresh mass, mean fresh mass and mean length of pods.The N content of the index leaf and N accumulation in shoots were linearly increased by the N rates, regardless of the N source, while the plant height and the pod’s characteristics werenotinfluenced by anyof the factors studied

“…Thus, research that focuses on the production of snap bean seeds is essential for this crop to establish itself from other species that have more improved production technology. Because the seeds are the genetic features vehicle for the implantation of any crop, this input is the primary concern in providing a uniform and productive crop (A. P. Oliveira et al, 2003).…”

Research on snap bean seed production is essential for this crop to compete against other species that have better production technologies. This study aimed to select a physiological quality evaluation test for snap beans to improve progeny selection strategies. The experiment was conducted in the Seed Analysis Laboratory at the Federal Institute of Goiano, campus Iporá-GO. Seed from thirteen progenies were evaluated for physiological quality from a breeding program conducted by the genetic breeding department of the State University of Goiás, campus Ipameri. Seeds were evaluated for moisture content, thousand-seed weight, biometry (length, width, and thickness), germination, seedling vigor classification, length and seedling dry mass, emergence in the field, and emergence speed index of seedlings in the field. The genetic variability in the evaluated characteristics indicated that genetic breeding can contribute to a better performance in snap bean seed physiological quality. The germination test, vigor classification, emergence, and emergence speed index of seedlings can be used to design strategies for snap bean population selection that produces more productive seeds.
