Abstract
- 【Objective】The paper aimed to screen the germplasm resources of Morus macroura with high comprehensive quality and meet the demand of diversified development for food.【Method】23 Morus macroura and 3 other mulberry varieties were collected and preserved in the provincial mulberry germplasm resource nursery garden of Yunnan province to determine 18 indicators such as fruit nutrition, active ingredients and antioxidant activity, and these indicators were comprehensively evaluated by correlation analysis, principal component analysis and cluster analysis.【Result】The 26 M.macroura germplasm resources had a single fruit mass of 1.15-8.38 g, hardness of 1.17-2.08 kg/m², moisture content of 63.23%-79.00%, juice yield of 45.28%-77.97%, pH of 2.22-4.05, soluble solids of 17.07%-35.50%, amino acid content of 6.29-27.93 mg/g, Vc content of 0.02-1.72 mg/g, total sugar content of 114.60-352.93 mg/g, reducing sugar content of 25.30-205.24 mg/g, total flavonoids content of 10.16-73.42 mg/g, total alkaloid content of 0.04-2.46 mg/g, total phenolic content of 0.61-2.68 mg/g, total anthocyanin content of 0.01-1.02 mg/g, total GABA content of 88.43-938.27 μg/g, total antioxidant capacity, ABTS scavenging capacity, and DPPH free radical scavenging capacity were 11.63-93.66, 11.32-7.53, and 9.61-65.09 mg/g water-soluble Vc equivalent, respectively. After principal component analysis, the 18 traits were combined into 6 principal component factors, with a cumulative contribution of 83.49%, which could better reflect the basic information of fruit quality.【Conclusion】The PCA results show that Yunsang 2, Hongfenjiaren, Guo 3, Hongxiangcheng, Heijinshen, Chaziyanhong, Hongyanzhiji and Zijinshen with the best fruit quality are suitable for deep development in Yunnan province as an excellent fruit mulberry resource; Single fruit weight, Vc, anthocyanins, SSC, amino acids, and total sugar are the core indicators for evaluating the quality of M.macroura fruits.
