为了筛选出适合湖北省种植的马铃薯(Solanum tuberosum L.)早熟品种,对引进的7个品种安排5个冬种点进行了适应性、丰产性和抗逆性的种植考察试验。结果表明,春薯4号因生育期适中、产量最高、商品性好、抗病性强,可作为早熟品种在湖北省示范推广;克新21因生育期早、单薯重和商品薯率高,可作为湖北省的早熟马铃薯补充品种;DE03-79-1、YS301两个品种产量高、抗病性强,但生育期较长,可作为中晚熟品种在山区示范种植。
In order to screen the precocious varieties of potato (Solanum tuberosum L.) suitable for planting in Hubei province, five winter planting sites for seven varieties introduced were surveyed for adaptability, high yield and stress tolerance. The results showed that, due to moderate growth period, highest yield, good commercial quality and strong disease resistance, Spring potato 4 could be used as a precocious variety for demonstration and promotion in Hubei Province. Because of its early growth period, sweet potato weight and commercial potato yield , Which can be used as a supplementary potato variety in Hubei province. DE03-79-1 and YS301 have high yield and strong disease resistance but longer growth period, which can be planted in the mountainous area as middle and late-maturing varieties.
