为创新马铃薯种植结构调整模式,提高种植效益,加快‘希森6号’在全国范围的推广应用,本研究在甘肃省的天水、定西,湖北省的五峰县、兴山县、巴东茶子店、建始龙坪、利川、天池山、竹山县9地布置品种示范试验,以当地主栽品种为对照,观察验证该品种综合性状的稳定性和适应性。试验结果显示,与当地主栽品种相比,‘希森6号’除在甘肃定西,湖北兴山县、竹山县增产幅度较小（分别为3.13%、7.71%和6.91%）外,其余6地都显著高于对照,例如湖北天池山增产36.01%、巴东县增产48.37%、建始龙坪增产34.39%、五峰增产51.60%、利川增产28.66%、甘肃天水增产28.63%。结果表明,‘希森6号’适应能力强,在各参试点均可正常生长、成熟,且产量均比当地主栽品种高。

To innovate the adjusting model of potato planting structure, improve planting benefits, and speed up the popularization and application of the potato variety ‘Xisen 6’ in China, variety demonstration tests were conducted in Tianshui and Dingxi of Gansu, and Wufeng, Xingshan, Badong Chazidian, Jianshi Longping, Lichuan, Tianchishan, Zhushan of Hubei, by taking local main varieties as control, to observe and verify the stability and adaptability of the comprehensive traits of ‘Xisen 6’. Compared with main local varieties, the tests showed that, except Dingxi, Xingshan and Zhushan had small yield increase (3.13%, 7.71%, and 6.91%, respectively), the remaining 6 test sites had significantly higher yield increase than the control, the yield increase in Tianchishan was 36.01%, in Badong was 48.37%, in Jianshi Longping was 34.39%, in Wufeng was 51.60%, in Lichuan was 28.66%, and in Tianshui was 28.63%. It is indicated that ‘Xisen 6’ has strong adaptability, can grow and mature normally in all test sites, and its yield is higher than that of main local varieties.
