摘　　要：为了挖掘高番茄红素含量兼具优异农艺性状的西瓜种质,对设施栽培的21份西瓜种质资源的农艺性状进行鉴定和评价,并采用超高效液相色谱法检测其番茄红素含量。农艺性状的鉴定和评价结果显示,21份西瓜种质资源的果实发育期在27.00~42.00 d,单果质量在1.71~8.53 kg,边部可溶性固形物含量(w)在7.00%~10.20%,中心可溶性固形物含量在10.00%~14.80%。21份西瓜种质资源的鲜质量番茄红素检测结果显示,番茄红素含量范围在46.53~95.78μg·g^(-1),变异系数达17.84%。其中,有3份种质资源的番茄红素含量>80μg·g^(-1),属极高番茄红素含量西瓜种质;有7份种质的番茄红素含量在70.13~78.57μg·g^(-1),属高番茄红素含量西瓜种质。并且,西瓜果肉瓤色与番茄红素、八氢番茄红素及γ-胡萝卜素的含量呈极显著正相关。瓤色可作为鉴定筛选高番茄红素含量西瓜种质的核心农艺性状,小果型西瓜种质W1-11和大果型西瓜种质All-Sweet Scarlet果实发育期分别为27 d和42 d,可作为高番茄红素含量的优质高产西瓜新品种选育的直接或间接亲本。In order to explore watermelon germplasm with high lycopene content and excellent agronomic traits,the agro-nomic traits of 21 watermelon germplasm resources under facility cultivation were identified and evaluated,and the lyco-pene content was detected by ultra performance liquid chromatography.The results of identification and evaluation of agronomic traits showed that the development period of the 21 watermelon germplasm resources ranged from 27 to 42 days,with single fruit mass ranging from 1.71 to 8.53 kg.The soluble solid content at the edge of the fruit ranged from 7.00%to 10.20%,while the soluble solid at the center ranged from 10.00%to 14.80%.The lycopene content in fresh weight ranged from 46.53 to 95.78μg·g^(-1),with a coefficient of variation of 17.84%.Among these,lycopene content of three germplasm resources were greater than 80μg·g^(-1),categorized as watermelon germplasm with extremely high lyco-pene content,and seven germplasms ranged from 70.13 to 78.57μg·g^(-1),categorized as watermelon germplasm with high lycopene content.The study also found that the flesh color of watermelon was significantly positively correlated with the content of lycopene,phytoene andγ-carotene.Therefore,flesh color can be used as a core agronomic trait for the identi-fying and selecting watermelon germplasm with high lycopene content.The small fruit watermelon germplasm W1-11 and the large fruit watermelon germplasm All-Sweet Scarlet,with fruit development periods of 27 days and 42 days,respectively,can be used as direct or indirect parents for breeding high-quality,high-yield and disease-resistant watermelon varieties with high lycopene content.
