马铃薯淀粉含量和淀粉产量的品种×年份互作以及稳定性分析
Variety × Year Interaction and Stability Analysis for Starch Content and Starch Yield in Potato
【摘要】 马铃薯适应性强、产量高,块茎富含淀粉,其淀粉品质优于其他作物。马铃薯淀粉加工需要品种产量高、淀粉含量高,且在年际间表现稳定。以垦区主栽品种‘延薯4号’为对照,评价6个马铃薯品种的块茎产量、淀粉含量、淀粉产量及其稳定性,以期筛选出适用于当地马铃薯淀粉加工的品种。试验于2019~2021年在克山农场进行,采用随机区组设计,4次重复。块茎产量、淀粉含量、淀粉产量品种×年份互作效应显著,所以需要进行品种稳定性分析。‘北薯2号’淀粉含量21.77%,淀粉产量11 304 kg/hm~2,均显著高于对照品种‘延薯4号’,且年际间表现稳定,表现出淀粉加工品种的潜力。‘东农321’淀粉含量14.82%,稳定性中等,块茎产量较高,为53 170 kg/hm~2,稳定性好,由于块茎产量较高,所以淀粉产量较高且表现稳定,可作鲜食和淀粉加工兼用型品种试种。研究结果可为马铃薯淀粉加工企业品种选择提供依据。
【Abstract】 Potato crop has wide adaptability and high yield, and tubers are rich in starch, which is superior in quality to the starch of other crops. Potato starch processor requires varieties with high yield and high starch content, and their performances are stable between years. The purposes of this study were to evaluate the tuber yield, starch content,starch yield, and stability of six potato varieties, using the main cultivated variety ’Yanshu 4’ in reclamation area as a control, in order to screen out varieties suitable for local potato starch processing. The experiment was conducted at Keshan Farm from 2019 to 2021, using a randomized complete block design with four replicates. The effects of variety ×year interaction for tuber yield, starch content, starch yield were significant, indicating that it is necessary to conduct a variety stability analysis. The starch content of ’Beishu 2’ was 21.77%, and the starch yield was 11 304 kg/ha, which are significantly higher than those of the control variety ’Yanshu 4’, and their performances were stable between years,showing its potential to be used as a starch processing variety. The starch content of ’Dongnong 321’ was 14.82%, and its stability was moderate. The tuber yield was 53 170 kg/ha, and its stability was good. Because of its higher tuber yield,the starch yield was also high, and the performance was stable, so it could be potentially used as a variety for both fresh consumption and starch processing. The research results would provide references for potato starch processing enterprises to select varieties.
