广西冬种加工型马铃薯品种比较试验

Comparative trial of introduced processing-purpose potato varieties for winter-planting in Guangxi

从美国引进8个加工型马铃薯品种在广西进行冬种栽培适应性试验。结果表明,Belmont品种出芽情况最好、分枝数最多、主茎较粗、叶片数较多、上等薯率较高;Salem品种出芽情况次之,产量最高、上等薯率较高;Elba品种植株生长较高、分枝数较多、主茎最粗、叶片数最多、上等薯率最高,这3个马铃薯品种均适宜在广西冬种。

The present study has been performed to evaluate the adaptabilities of eight processing-purpose potato varieties （winter-planting） introduced from U.S., in Guangxi. The results showed that potato variety Belmont had the best germination, maximum number of branches, thick main stem, higher leaves and higher rate of first-class tubers. Variety Salem had better germination, highest yield and higher rate of first-class tubers. Variety Elba had higher plant height, more branches, thickest main stem, higher leaves and the highest rate of first-class tubers. So these potato varieties could be suitable for winter-planting in Guangxi.
