| Sumario: | The yield and physical quality of common bean grains influenceprofitability and marketing. Its quantification allows the identification of genotype highlights. The aim of thestudy was to evaluate these aspects in Azufrado Higuera and Azufrado Noroeste varieties and Mo 19-20-ERR2-9, Mo 19-20-ERR2-11, and Mo 19-20-ERR2-12 advanced lines. The experimental design was a randomized complete block withfour replications. The yield (t ha-1), 100-grain weight (HGW, g), and initial grain brightness (%) were measured on dry and clean samples. For each grain, digital image analysis was used to measure size (mm2), length, width, perimeter (mm), circularity, color, brightness, and luminosity. The yield was from 2.14 to 2.45 t ha-1 (p ≥ 0.05). Grain size correlated (p ≤ 0.05) with HGW (r = 0.97) and with its dimensions (r ≥ 0.94). Grain luminosity was higher in advanced lines (DSH = 0.74, p ≤ 0.05). Larger grains with less darkening evidenced better physical quality in Mo 19-20-ERR2-9 and Mo 19-20-ERR2-11 (p ≤ 0.05). Brightness and luminosity allow the identification coat darkening. Oxidation is slow in Azufrado Noroeste and Azufrado Higuera varieties, whereas Mo 19-20-ERR2-9, Mo 19-20-ERR2-11, and Mo 19-20-ERR2-12 lines have resistance. |
