摘要
为筛选适宜湖南省种植的马铃薯新品种,2009年引进7个马铃薯新品种进行田间比较试验。结果表明:克200373-218产量最高,达21 900 kg/hm2,比对照东农303增产44.6%,达到极显著水平;克新17号和克新19号产量分别比东农303增产5.0%、3.0%。根据综合表现,克200373-218、克新17号和克新19号抗性强、综合性状表现好,均适宜在湖南省种植;克新18号、克200373-205、红皮、马尔科均较对照减产,有待进一步试验。
In order to select appropriate potato varieties that suit to planting in Hunan province, seven introduced potato varieties were taken to conduct field comparative test in 2009. The results showed that the Kexin200373-218 recorded the highest yield (21 900 kg/hm2), which increased by 44.6% than control's (Dongnong303) and reached significant level (P〈0.01); in comparison with Dongnong303, the yield of Kexin No.17 and Kexin No.19 increased by 5.0% and 3.0%, respectively. According to the overall performances, the Kexin200373-218, the Kexin No.17 and the Kexin No.19 all have strong resistance and good comprehensive performances, which are suitable to cultivate in Hunan province; in comparison with control, the yield of Kexin No.18, Kexin200373-205, Red and Marco all decreased, who need to be tested further.
