鄂尔多斯地区露地小果型西瓜材料的比较

Comparison of Small-fruit Watermelon in Ordos Open Field

为选育鄂尔多斯地区优良的小果型西瓜自交系,对16份小果型西瓜材料进行了田间试验和指标测定,比较了各材料在果实发育期、单果重、果肉可溶性固形物含量及抗病性方面的差异,通过灰色关联分析进行了综合评价。结果表明,西瓜材料190491单果重、果肉可溶性固形物含量、抗病性均显示出良好特性,190292在果实发育期、单果重、抗病性方面表现突出,19050为灰色关联分析中综合性状最优。研究发现,材料190491、190292、19050可以作为鄂尔多斯地区小果型西瓜杂交育种中优良亲本材料加以利用。

Field experiment on 16 small-fruit watermelon was performed in Ordos area,in order to select a good inbred line of small fruit watermelon.Difference among all treatments upon fruit development period,fruit weight,flesh soluble solids content and disease resistance were compared,and all treatments were comprehensively evaluated with gray correlation analysis.Results indicated that 190491 all showed good characteristics for fruit weight,flesh soluble solids content and disease resistance.190292 was outstanding in fruit development period,fruit weight and disease resistance.19050 was comprehensively evaluated as the best by gray correlation analysis.Results showed that 190491,190292 and 19050 could be used as excellent parents in crossbreeding of small fruit watermelon in Ordos.
