Abstract: | The genetic diversity in agronomic, seeds (physicochemical, hydration, textural and cooking) and flour (pasting and gel texture) characteristics amongst 71 field pea lines was studied. L∗-, a∗-, b∗-values, seed weight, density, hydration capacity, swelling capacity and cooking time ranged between 43.6 and 67.1, −2.3 and 6.2, 5.8 and 17.4, 4.26 and 25.65 g/100 seeds, 0.55 and 2.01 g/ml, 0.05 and 0.31 g/seed, 0.02 and 0.76 ml/seed and 45 and 81 min, respectively. Amylose content of starch ranged between 21.4% and 58.3%. Pasting temperature, peak viscosity, breakdown, final viscosity and setback of flours from different lines ranged from 73.5 to 81.5 °C, 533 to 3000, 8 to 187, 121 to 2276, and 183 to 998 cP, respectively. The frequency distribution and principal component analysis revealed significant variation in quality traits amongst the 71 field pea lines. |
