摘要： Phenotypic variation in peach tree and fruit characteristic was investigated using 7 desirable cultivars, namely A669, Texas y-455, Florida King, Arctic Fantacy, Spring Creast, Micholea and Swanee. All cultivars were grown at the Experimental Peach Block at Barani Agriculture Research Institute (BARI), Chakwal, Punjab -Pakistan. Tree traits such as growth habit, leaf characteristics, flower characteristics, morphological and biochemical fruit traits were evaluated by using IBPGR peach descriptors. Extensive variation was found among the cultivars for various traits, including tree growth (weeping, compact or open whereas), leaf length (9.0 +/- 0.8 to 12.0 +/- 0.4 cm), leaf width (2.6 +/- 0.1 to 3.3 0.2 cm), fruit weight (45.6 +/- 3.3 to 107 +/- 8.8 g) and stone weight (4.3 +/- 0.2 to 7.5 +/- 0.4 g). Besides, a significant variation among the various cultivars has also been observed regarding, titratable acidity (0.64 +/- 0.02 to 1.19 +/- 0.04%), degrees Brix (7.17 0.62 to 11.27 0.21), ripening index (6.02 +/- 0.72 to 17.2 +/- 0.44), Vitamin C (75.3 +/- 15 to 116.1 +/- 10.5 mg 100 0), total sugar (13.52 +/- 0.50 to 20.84 +/- 1.23%), reducing sugar (5.68 +/- 0.11 to 7.25 +/- 0.51%), non-reducing sugar (4.12 0.45 to 10.77 +/- 0.8%), total phenolics (176.20 +/- 7.18 to 317.72 4.66 mg GAE 100 g(-1)), radical scavenging activity (44.25 +/- 0.28 to 78.17 +/- 1.43%) and reducing power (0.12 +/- 0.1 to 0.22 +/- 0.03). Similarly, a significant correlation was noticed between many tested traits.
