“…As for the growth habit, the snap bean can be classified as undetermined, or climbing and determined, or bush. Cultivars of indeterminate growth have a vegetative apical meristem that allows the continuous growth of plants, with they commonly achieveing higher yields when compared to bush cultivars (Wahome et al, 2013), up to more than 30 t ha -1 , as reported by Almeida et al (2014). However, such cultivars need more intense care regarding their crop management, causing a greater demands on labor, since they need tutoring, and, due to their longer cycle, they are more subject to the incidence of pests and diseases, thus increasing the overall production costs (Wahome et al, 2013;Gomes et al, 2017).…”

Snap beans are one of the ten most consumed vegetables in Brazil, and there are few cultivars available in the Brazilian market. This study aimed to evaluate the seed yield of 20 snap beans genotypes under conventional and organic systems under Brazilian Cerrado conditions. Plant height, number of seeds per pod, weight of 100 seeds and yield were evaluated. For plant height and number of seeds per pod, the 20 genotypes were equal in the conventional cultivation system. In the organic system, the 20 genotypes formed two distinct groups regarding these variables. In the conventional system there were no significant differences between genotypes regarding the weight of 100 seeds, the mean mass in this system was 19.08 g, but there were differences in the organic system. Regarding yield, there was significant difference between the genotypes for both cultivation systems, organic and convetional. Production of snap bean cultivars in the organic system was shown as viable and promising. The genotypes Amarelo Japonês, Hab 1 and Tendergreen Improved stood out among the most productive in both systems.

“…The snap bean (Phaseolus vulgaris L.) is a vegetable crop that belongs to the same botanical species of common bean, in which the main difference is in the consumption of fresh pods (FILGUEIRA, 2012). In Brazil, the main cultivars have indeterminate growth habit and presents fresh pod yields of 25 to 30 t ha -1 , while determinate growth habit cultivars reach the half of this performance (ALMEIDA et al, 2014).…”

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

Distinctness, uniformity and stability and GT biplot tests for the selection of snap bean lines

et al. 2020

The lack of records about snap bean cultivars is one of the obstacles that has led to a yield gap and low prominence of the crop. This work aimed at indicating snap bean lines obtained by the Breeding Program of the Universidade Estadual do Norte Fluminense (UENF) to assess their performance and to apply for a certificate of plant variety protection. The study was managed using a randomized block design with three replicates in a greenhouse at the Research Support Unit of the UENF. Nine candidate lines were compared to the commercial cultivar “Topseed Blue Line” in accordance with 56 descriptors set by the National Plant Variety Rights. All lines presented themselves as homogeneous. The L31 line provided a total of 30 different descriptors of the commercial cultivar. For the quantitative data added to the Distinctness, Uniformity and Stability, (DUS) tests, the analysis of variance was performed and the GT biplot generated by the R software. Variability was noticed among the genotypes for all assessed traits, excepting days until germination and seed thickness. The lines that showed the best mean performance were L6, L7, L10, L11, and L13. Among those, the L6 and L11 lines provided higher stability.
