Common bean, Phaseolus vulgaris L., is historically significant crop that plays vital role in global food security. However, limited research exists on the genetic diversity of common bean in Pakistan that specifically suit the climatic conditions of a particular region. To address this gap, ten different common bean varieties were evaluated at the Cereal Crop Research Institute in Nowshera KPK. Randomized complete block design with three replications was employed. Agronomic and quality traits were analyzed. Results revealed that variety China exhibited the tallest plants (62) with more number of branches (20), while Gorilla and Swat Red displayed the shortest plants (31 and 28) with Swat Red and Swabi 1 having limited branching (9 each). China also showed delayed flowering (55), while Swat 1 and Swat Red exhibited early flowering (37 and 39 respectively). Gorilla and Nifa R outperformed other varieties producing more pods ( 22) and seeds pods -1 (7.3). The highest seed yield was also recorded for Gorilla (1984 kg ha -1 ) and Nifa R (1946 kg ha -1 ), while Afghani (1430 kg ha -1 ) and Swabi 1 (1395 kg ha -1 ) had the lowest. In terms of quality traits, Nifa R showed the highest protein content (21 g), while Gorilla had the lowest seed moisture content (9.9 %). Nifa Y showcased the highest iron content (105 mg kg -1 ), and Nifa R displayed the highest zinc content (30 mg kg -1 ). Newly developed Nifa R and Y varieties and gorilla variety from Swat is considered to be well suited in agro climatic conditions of Nowshera region.

“…Advances in plant breeding and phenotyping contributed to elucidating physiological mechanisms related to the description of developmental stages, dry matter accumulation dynamics per organ, source-sink relationships, and plant growth simulation models [20,21], which are of great utility for selecting parents with traits of interest [14] in favor of improving the response of common beans to stress conditions [13,16]. One of the most important breeding traits for genetic enhancement is biofortification, which seeks to biologically increase Fe and Zn concentrations in the grain [22][23][24]. Results on screening of seeds of bean germplasm indicated an average concentration (mg kg −1 ) of Fe and Zn of 55 and 28, respectively, with extremes of 102 for Fe and 54 for Zn [25].…”

One of the strategies to combat micronutrient malnutrition is by developing biofortified common bean lines (Phaseolus vulgaris L.) capable of tolerating different stress conditions. In this study, the adaptive responses of different biofortified bean lines grown under combined stress of acidic soil and high-temperatures were evaluated in the Colombian Amazon. A total of 247 common bean lines from the Mesoamerican gene pool were used to determine the adaptive response in terms of phenological, physiological, and agronomic behavior under combined stress conditions. The lines tested were obtained from different single crosses, double crosses, and backcrosses between different bean materials, of which 146 were obtained from F4 families with high iron (Fe) content in seed and 99 common bean lines from F5 families. Different bean lines had grain yields (GY) higher than 1400 kg ha−1 from the F5 (lines: 859, 805, 865, and 657) and F4 (lines: 2853 and 2796) families. The superior performance of these lines was related to a higher photosynthate partitioning that has allowed an increase in pod formation (pod partitioning index, PPI) from the canopy biomass (CB) and grain filling (pod harvest index, PHI; harvest index, HI), resulting in higher values of GY. Values of GY were correlated with CB (r = 0.36), PPI (r = 0.6), PHI (r = 0.68), and HI (r = 0.8, p < 0.001). This increase in agronomic performance is due to a greater allocation of energy to the photosynthetic machinery (ΦII) and its dissipation in the form of heat (ΦNPQ), with increases in the leaf temperature difference (LTD). Based on the results obtained, six biofortified lines of common bean (lines F5: 859, 805, 865, and 657; lines F4: 2853 and 2796) showed traits of tolerance to combined stress and can serve as progenitors to increase Fe and Zn concentration in the seeds of lines that tolerate the combined stress from acidic soil and high temperature in the Colombian Amazon region.
