中薯系列马铃薯新品种比较试验

Comparative Experiment of Zhongshu Series Potato New Varieties

为选育出适合湖南冬闲田种植的高产、优质马铃薯新品种,以中薯5号为对照,对17个中薯系列马铃薯新品种开展比较试验。结果表明,中薯18号、中薯20号、中薯17号、中薯9号和中薯10号等5个品种产量和抗病性表现较好。中薯10号是综合表现最好的一个早熟品种,薯皮光滑,芽眼浅,产量30 917 kg/hm^2,较对照增产7.5%。中薯18号中晚熟,薯形椭圆,抗病性强,产量表现最好,为33 417 kg/hm^2,较对照增产16.2%。结薯早、高产、抗性强的中晚熟品种如果提早收获也可以在冬闲田与水稻轮作。

In order to breed out new potato varieties with high yield and high quality and suitable for the cultivation in winter fallow fields in Hunan,a comparative experiment of 17 new varieties of Zhongshu series was carried out,‘Zhongshu 5'was used as control. The results showed that the yield and disease resistance of‘Zhongshu 18',‘Zhongshu 20',‘Zhongshu 17',‘Zhongshu 9'and‘Zhongshu 10'were better. The best comprehensive performance of early maturing variety was‘Zhongshu10',which has smooth skin,shallow eye. Its yield was 30 917 kg/ha and increased 7. 5% compared with the control.‘Zhongshu 18'was the middle-late maturing variety,oval shape tuber,strong disease resistance,its yield was 33 417 kg/ha,the highest,and increased 16. 2% compared to the control. The middle-late maturing variety with early tuber formation,high yield,strong disease resistance could also be planted with rice rotation in the winter fallow field if early harvest.
