“…By the estimates of the GCA effects on the PW, SWPP, and NSPP traits, it can be confirmed that the L1 Progenitor 19 (UENF 1445) and L3 (Top Seed Blue Line) genitors showed high and positive estimates, which suggests a possible contribution to the increase of these traits (Table 5). Similar results for pod weight and number of seeds per plants were found by Rainey and Griffiths (2005) and Francelino et al (2011). With regard to PL, the L10 (UENF 7-10-1) and L11 (UENF 7-12-1) genitors were the ones that presented positive values for GCA, which allows their indication in crosses to promote gains for that trait.…”

The search for genetic material of snap beans with desirable yield traits is of utmost importance for yield increase in Brazil. We evaluated 12 snap bean genotypes by diallel crosses that presented characteristics of interest, so as to select the best genitors to generate productive populations in the snap bean breeding program of the Universidade Estadual do Norte Fluminense in Rio de Janeiro state, Brazil. Diallel crosses were performed applying Method 2 of Griffing. The F 1 generation, composed of 36 hybrid combinations, was evaluated in a greenhouse, in a completely randomized design with two replicates. The traits evaluated were: pod weight, length, width and thickness, number of seeds and seed weight. There were significant differences among genotypes for most variables, indicating genetic variability between snap bean lines. The following genitor genotypes proved to be the most suitable when the trait to be improved was yield: Top Seed Blue Line, UENF 1445, UENF 7-20-1, and UENF 7-10-1. The hybrids with higher values of combining ability estimates are indicated to generate promising segregating populations. Thus L3 (Top Seed Blue Line) × L18 (UENF 9-24-2), and L12 (UENF 7-14-1) × L1 (UENF 1445) hybrid combinations showed the best estimates of specific combining ability for the traits under evaluation, suggesting a high probability of obtaining superior ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (2): gmr18214 A.B.S. Gomes et al. 2 genotypes. The efficiency of selection for these traits is based on additive genic action and demonstrates progress in the of snap bean breeding program.

“…Rio de Janeiro State is one of the largest national markets of snap beans and is responsible for 21% of the total produced in the Southeast of the country. However, despite being valued, this culture presents low productivity in the North and Northwest of the state due to its lack of cultivars adapted to these regions (Vilela et al;2009;Francelino et al, 2011). It is possible to obtain superior and adapted genotypes by means of genetic breeding techniques.…”

The purpose of this research was to select the development of superior genotypes of snap beans adapted to edaphoclimatic conditions of the North and Northwest of Rio de Janeiro State, Brazil, applying the mixed model methodology. The test was installed and carried out in the experimental area of the Instituto Federal Fluminense (IFF), located in the municipality of Bom Jesus do Itabapoana, Rio de Janeiro State, Brazil, using the modified SSD (Single Seed Descent) method. The experiment was of randomized block design with three replications. We evaluated weight of pod per plant and number of pod per plant in ten progenies from the snap bean breeding program of the Universidade Estadual do Norte Fluminense (UENF); individual plants were assessed in each plot and in each replication (block). All progenies had mean productivity superior to 1 kg of pod per plant and 144 pods per plant. The 7 and 2 progenies, which came from the crossings between (UENF 7-5-1) L6 × L20 (UENF 14-3-3) and (UENF 7-5-1) L6 × L13 (UENF 7-20-1), stood out from the others, as they led to a higher predicted additive gain for the two evaluated traits. We concluded that the selection for production of snap beans and grains applying BLUP enabled the prediction and achievement of significant genetic gains for breeding snap beans for subsequent generations

“…These have contributed to the expansion of snap beans crop in several regions of Brazil, with it standing out as a good low operational cost option for Fall/ Winter in irrigated areas, since they enable the mechanization of most cultivation operations. Moreover, these cultivars produce good quality pods, which in turn has led to the greater demand for this group by producers (Francelino et al, 2011;Andrade et al, 2017;Peixoto & Cardoso, 2016;Vaz 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.
