Improvement in the Stability and Yield Performance of a Snap Bean Cultivar

Abstract Six different common bean cultivars (BRS Embaixador, BRS Pitanga, BRS Estilo, Pérola, BRS Campeiro and BRS Esplendor) were characterized aiming to determine possible uses for them in various food products. The samples were analysed to determine their chemical composition, weight per hundred beans, pH, water and oil absorption capacities (WAC and OAC, respectively), foaming at pH 2.5, 5.6 and 8.0 and emulsifying properties. The relationship between the physicochemical and functional properties was described using the Principal Component Analysis (PCA). The results of the chemical composition, weight per hundred beans, WAC and OAC showed differences even between cultivars of the same commercial group. Foaming also varied between the cultivars and foaming capacity and stability were greatest at pH 5.6 and 8.0. The emulsifying capacity proved quite high for all cultivars, as well as the stability of the emulsion. According to these properties, with the contribution of the PCA, each different bean cultivar can be destined to specific applications according to its physicochemical properties.

Eight snap bean (Phaseolus vulgaris L.) cultivars and lines were grown under an organic management system in 2011 and 2012 in Lajas, Puerto Rico. Bean genotypes used in the trial were the commercial cultivars 'Contender', 'Festina', 'Fresh Pick', 'Jade', 'Nash' and 'Provider', and two experimental breeding lines PR1018-1 and PR1018-5. In 2011, 'Provider' and PR1018-5had the highest yields, with 11.2 and 11.1 t/ha, respectively, but these were not significantly different from the yields of 'Contender', 'Festina', PR1018-1 or 'Nash'. 'Jade' had the lowest yield, with 6.5 t/ha. In 2012, the highest yielding cultivar was 'Festina', with 14.6 t/ha, which was not significantly different from 'Nash' (13.8 t/ha), PR1018-5 (12.6 t/ha) or 'Jade' (12.5 t/ha). 'Contender' (9 t/ha), 'Provider' (8.4 t/ha) and 'Fresh Pick' (8.4 t/ha) had the lowest yields. This study has shown that snap beans can be successfully grown in Puerto Rico under an organic management system, with yields similar or superior to conventionally produced snap beans.

Calcium ions (Ca) play an important role in many biochemical processes, delaying senescence and controlling physiological disorders in fruits and vegetables. The objective of this experiment was to analyze the effect of increasing calcium concentrations in snap beans. Snap bean cultivar UEL 1 was sown in sand containing 80 mg L-1 of calcium supplemented with nutrient solution, plus calcium at different contents: 0, 75, 150 and 300 mg L-1. Ca was mainly recovered in the shoots, followed by roots and pods. Calcium concentrations in the pods were 130, 259, 349 and 515 mg 100 g-1dry matter on a dry weight basis, in relation to the enhancement of calcium contents in the nutrient solution, respectively. A negative relationship between nitrogen content in the pods and calcium concentration in the nutrient solution was observed. Pods from plants grown in a solution without Ca presented necrosis in their apical region. Dieback of roots, shoots and young leaves also occurred under low calcium supply. Dry matter of pods, roots and shoots, number of pods per plant, pod weight and pod length increased proportionally to calcium concentration in solution. Increasing rates of calcium improved biomass production in snap bean cultivar UEL 1.

Simple Interaction

The objective of this experiment was to assess the genotypes by environment interaction for eight morphoagronomic traits in thirty F7:8 snap bean superior lines and evaluate the pod yield stability. The experiments were carried out in the cities of Bom Jesus do Itabapoana, Campos dos Goytacazes and Itaocara, located in the Northern and Northwestern regions of Rio de Janeiro State, Brazil. Experiments were designed in randomized blocks with two replications, using the traditional method (Yates & Cochran, 1938) and the methods proposed by Plaisted & Peterson (1959), Wricke (1965), Kang & Phan (1991) and Lin & Binns (1988), as well. Only the average fiber content in pods revealed no significant genotype x environment interaction, whereas most of the traits showed simple interaction, including pod yield. The results obtained using the methods of Plaisted & Peterson (1959) and Wricke (1965) agreed to a far extent and had a moderate estimate (0.6131) in relation to the traditional method. Both methods highlighted genotypes with pod yield close to the general average, i.e., around 7,546.46 kg ha-1. Kang & Phan's (1991) algorithm was more efficient in optimizing the stability estimates obtained using the methods of Plaisted & Peterson (1959) and Wricke (1965) than the traditional method. Lin & Binns' (1988) procedure revealed the most stable, responsive and productive progenies. Progenies 04, 03 and 10 stood out in all environments.

Rate Of Increase

Sugars, including glucose, fructose, and sucrose, contribute significantly to the flavor and consumer acceptance of snap beans (Phaseolus vulgaris L.). Sugar accumulation and changes in sugar profiles during snap bean development contribute to overall assessments of quality for breeding lines and cultivars. Developing fruit from a diverse group of four snap bean cultivars containing Andean germplasm and one Mesoamerican dry bean cultivar were sampled at 5-day intervals from 10 to 30 days after flowering over 2 years. Glucose, fructose, and sucrose in pod and seed tissue was quantified using high-performance liquid chromatography. Percent seed mass relative to pod mass increased with days after flowering, but the rate of increase was heterogeneous among cultivars. Significant differences in sugar accumulation patterns of mono- and disaccharides were observed with time of development and between pods and seeds. Glucose and fructose decreased rapidly in pods and seeds with time after flowering. In contrast, sucrose concentration increased in pod tissue but remained constant in seeds of the snap bean cultivars with time after flowering. The patterns of changes in pod and seed sugar concentrations with time after flowering were similar among all snap bean cultivars. In contrast to the snap beans, seed sucrose increased with time after flowering in the Mesoamerican dry bean cultivar Puebla 152. No year by day after flowering interactions were observed for sugar accumulation patterns or sugar concentrations. Younger snap beans had the highest sweetness index based on observed sugar concentrations, percent seed mass, and perception of relative sweetness by the human palate. Although mean sweetness varied between cultivars, the rate of decrease in sweetness with time was the same for all five cultivars. These findings indicate that variation for sweetness exists in snap beans and can be exploited by breeding to develop cultivars with a potentially more desirable, sweet flavor.
