鄂尔多斯地区西瓜杂交组合比较试验及灰色关联分析

Comparison of Watermelon Hybrid Combination and Grey Relational Analysis in Ordos

长期以来西瓜在鄂尔多斯市沿黄河地带广泛栽培。为选育适合鄂尔多斯地区的优良西瓜品种,在达拉特旗、准格尔旗两个不同土壤类型试验点,对4份露地西瓜杂交组合进行了田间试验和指标测定,比较了各组合在单果重、果皮厚度、果肉含糖量及抗病性方面的差异,通过灰色关联分析进行综合评价。结果表明,西瓜杂交组合B在单果重、抗病性方面显示出良好特性,组合C在单果重、果肉含糖量方面表现比较突出,组合D在果皮厚度、抗病性方面表现较好,组合B为灰色关联分析中综合性状最优。研究认为,西瓜杂交组合B可以作为适合鄂尔多斯地区的西瓜杂交组合继续进行试验。

Watermelons has been widely cultivated along the Yellow River in Ordos for a long time.In order to select and breed excellent watermelon varieties suitable for Ordos area,field experiments and index determination were carried out four watermelon hybrid combinations on open field in two different soil type test sites in Dalat and Zhungeer banner.The differences in single fruit weight,peel thickness,sugar content in pulp and disease resistance of each combination were compared,and the comprehensive evaluation was carried out by grey correlation analysis.The results showed that watermelon hybrid combination B showed good characteristics in single fruit weight and disease resistance,combination C showed outstanding performance in single fruit weight and pulp sugar content,combination D showed good performance in peel thickness and disease resistance,and combination B was the best comprehensive character in gray correlation analysis.It is believed that watermelon hybrid combination B can be used as a watermelon hybrid combination suitable for Ordos area for further experiments.
