摘要:

为丰富福建省彩色马铃薯育种的种质资源,本研究选取14个彩色马铃薯品种作为供试材料,首先,对各品种的产量和营养品质表现进行分析;随后,采用SSR分子标记开展遗传多样性分析。在营养品质与产量方面,各品种表现各异。‘黑美人’的花青素含量最高,达到41.83 mg/kg;‘福彩薯2号’在蛋白质含量、产量、商品薯率上均表现最优,分别为2.34 mg/g、31030.75 kg/hm2和89.54%;‘久恩红’的Vc含量最高为26.27 mg/kg,‘闽薯11号’的干物质含量最高为23.91%。在遗传多样性方面,14份品种的遗传距离在0.162~0.603之间,平均值为0.425。其中‘福彩薯2号’、‘紫云1号’、‘华颂66’等品种在福建省综合表现良好,这些品种可为福建省选育新品种提供亲本材料,同时也能为福建省马铃薯育种的理论研究提供参考。

Abstract:

In order to enrich the germplasm resources of color potato breeding in Fujian Province, 14 color potato varieties were used as the test materials. Firstly, the yield and nutritional quality performance of the varieties were analyzed, and then SSR molecular markers were used for genetic diversity analysis. The results showed that among all varieties, the anthocyanin content of 'Hei Meiren' was the highest at 41.83 mg/kg, while the protein content, yield and commercial potato rate of 'Fucaishu No.2' were the highest, which were 2.34 mg/g, 31,030.75 kg/hm2 and 89.54% respectively. The highest Vc content of 'Jiu En Hong' was 26.27 mg/kg, and the highest dry matter content of 'Minshu No.11' was 23.91%. The genetic distances of the 14 varieties ranged from 0.162 to 0.603, with an average of 0.425. Among them, varieties such as 'Fucaishu No.2', 'Ziyun No. 1', and 'Huasong 66' have performed well comprehensively in Fujian Province. They can provide parent materials for the selection and breeding of new varieties in Fujian Province, and at the same time offer references for theoretical research on potato breeding in Fujian Province.
