摘要
【目的】为解决广西冬种马铃薯新品种偏少、产量较低等问题,有效利用广西地区冬闲田,进一步提高复种指数。【方法】以东农303为对照,对15个供试马铃薯品种进行引种试种,生长期观察其农艺性状,收获后测定薯块经济性状及鲜薯产量。【结果】薯皮外观除延薯4号、3013为略麻皮以外,其余品种均比较光滑;肉色类型分别为白色、黄色和淡黄色3种,均为市场常见颜色;克新1号、克新4号、丽薯7号、延薯4号、坝薯10号和对照品种芽眼深浅中等,其余品种芽眼较浅;费乌瑞它和延薯4号的薯块大小整齐,其余品种薯块大小整齐度中等或不整齐;费乌瑞它产量最高,其次为宣薯2号、3013、中薯5号和冀张薯8号,分别较对照增产17.07%、13.93%、12.28%、4.27%和2.79%。【结论】初步筛选出宣薯2号、中薯5号、冀张薯8号、3013等4个马铃薯品种,可以进行下一步的生产试验和示范;其余品种需进一步种植观察。
[Objective] The present work was conducted to identify and demonstrate the high yielding potato varieties and to utilize them effectively in the fields left after harvesting of summer planted crops, as well as to increase the multiple crop index. [ Method ] Fifteen potato varieties have been introduced and planted in field in a randomized block design experiment with three replications. Variety Dongnong 303 was used as control. The agronomic and economic traits and yield were determined in field test. [Result] Potato peel appearance of the tested varieties were all smooth, except Yanshu 4 and 3013. The flesh color among them was found three kinds, viz., white, yellow and light yellow, which were common in the market. The eye depth of Kexin 1, Kexin 4, Lishu 7, Yanshu 4, Bashu 10 and eontrol variety was moderate, while that of the others was lighter. The tube size of Feiwuruita and Yanshu 4 was regular, while the uniformity of others was moderate or irregular. The yield of Feiwuruita was the highest, followed by Xuanshu 2, 3013, Zhongshu 5 and Jizhangshu 8, were 17.07, 13.93, 12.27, 4.27 and 2.79%, respectively. [Conclusion] The preliminary results showed that four varieties Xuanshu 2,17.07,Zhongshu 5, Jizhangshu 8 and 3013 performed well, and could be included in production trial and demonstration in the future. The others performed commonly, and needed to be investigated in next year.
