彩色马铃薯产量和品质性状评价

Assessment of Yield and Quality Traits of Color Potato

彩色马铃薯中含有丰富的花青素,具有很好的抗氧化功能和药用价值。为明确不同彩色马铃薯产量及品质差异,进而筛选高产优质的彩色马铃薯品种,试验以‘大同里外黄’为对照,11个彩色马铃薯为研究材料,测定其产量性状与品质性状,并分析了短期贮藏下彩色马铃薯中花青素的含量变化。‘民丰红’的产量最高,达33 558 kg/hm^(2),与对照品种‘大同里外黄’(22 550 kg/hm^(2))差异显著。‘民丰红’的综合性状最好,其次是‘永丰3号’‘青薯9号’。与贮藏前相比,贮藏30 d彩色马铃薯块茎中花青素含量均降低;与贮藏30 d相比,贮藏60 d 5个品种(系)花青素含量升高,7个品种(系)含量降低,但均低于贮藏前马铃薯块茎花青素的含量。研究为生产筛选出了高产或综合性状好的彩色马铃薯品种,并明确了短期贮藏下彩色马铃薯块茎中花青素的含量变化规律。

Color potatoes are rich in anthocyanins, which have good antioxidant function and medicinal value. In order to clarify the differences in yield and quality of different color potatoes, and then screen color potato varieties with high yield and good quality, the yields and quality traits of 11 color potato varieties(lines) were measured using’Datongliwaihuang’ as a control, and the anthocyanin change patterns under short-term storage was analyzed in this experiment. The yield of ’Minfenghong’ was the highest, reaching 33 558 kg/ha, which is significantly different from the control variety ’Datongliwaihuang’(22 550 kg/ha). ’Minfenghong’ had the best comprehensive characters, followed by’Yongfeng 3’ and ’Qingshu 9’. Compared with those before storage, the anthocyanin content in color potato tubers stored for 30 days decreased;compared with 30 days storage, the anthocyanin content of five varieties(lines)increased and that of seven varieties(lines) decreased after 60 days storage, but all of them were lower than that of potato tubers before storage. In this study, color potato varieties with high yield or good comprehensive traits are screened for production, and the change pattern of anthocyanin content in color potato tubers during short-term storage is clarified.
