基于隶属函数法对34份黄皮厚皮甜瓜种质资源的综合评价

Comprehensive Evaluation of 34 Varieties of Yellow-skinned Muskmelon Based on the Membership Function Method

为筛选出适合海南地区种植的黄皮类型厚皮甜瓜品种,利用方差分析和隶属函数法,对供试的34个黄皮类型厚皮甜瓜品种的产量及品质等性状进行综合评价。结果表明:34个品种中27个肉色为红色,果形指数范围1.03~1.79,肉质以脆为主;火凤凰6号产量最大,为63000 kg/hm^(2),显著高于其他品种;蜜(1)、Ds-85、k2-3、ST19-4、Ds-69心糖含量显著高于其他品种,分别为17.47%、17.50%、17.57%、17.60%、17.67%;ST19-5、k2-3边糖含量显著高于其他品种,分别为13.07%和13.43%;隶属函数法综合评价表明,火凤凰6号总隶属函数值最大,排名第1;k2-1、k2-4、君网蜜3号、k2-3位居前5,可以重点引进。

In order to screen out yellow-skinned muskmelon varieties suitable for planting in Hainan, 34 varieties of yellow-skinned muskmelon were selected to evaluate their yield and quality traits comprehensively by using variance analysis and the subordinate function method. The results showed that 27 of the 34 muskmelon varieties were red and mostly crispy in fruit flesh, with the fruit shape index ranging from 1.03 to 1.79. Muskmelon ‘Huofenghuang 6’ yielded the highest, 63 000kg·ha^(-1), which was significantly higher than that of the other varieties. The muskmelon varieties Mi(1), Ds-85, k2-3, ST19-4and Ds-69 were significantly higher in soluble solids content in the center of the fruit flesh than the other varieties, which were 17.47%, 17.50%, 17.57%, 17.60% and 17.67%, respectively. The varieties ST19-5 and k2-3 had significantly higher soluble solids contents in the outer portion of the fruit flesh than the other varieties, which were 13.07% and 13.43%, respectively.Comprehensive evaluation of all the varieties by the membership function method showed that the variety ‘Huofenghuang 6’was the highest in total membership function value, followed by the varieties k2-1, k2-4, Junwangmi 3 and k2-3. The top 5varieties can hence be considered for introduction.
