摘要:為了篩選出適合湖北省種植的馬鈴薯(Solanum tuberosum L.)早熟品種,對引進的7個品種安排5個冬種點進行了適應性、豐產性和抗逆性的種植考察試驗。結果表明,春薯4號因生育期適中、產量最高、商品性好、抗病性強,可作為早熟品種在湖北省示范推廣;克新21因生育期早、單薯重和商品薯率高,可作為湖北省的早熟馬鈴薯補充品種;DE03-79-1、YS301兩個品種產量高、抗病性強,但生育期較長,可作為中晚熟品種在山區示范種植。

Abstract: In order to find early potato varieties suitable for Hubei Province, seven newly introduced varieties were planted in five winter planting areas to test their adaptability, output and resistance. The results showed that the Spring Potato No. 4, with moderate growth period, high yield, good quality and excellent disease resistance, could be used as an early potato variety in Hubei Province; Kexin No.21, with short growth period, big potato tube and the highest goods ratio, could be used as a complement of early potato; DE03-79-1 and YS301 could be demonstrated in the mountain areas as middle or late-maturing varieties.
Key words: potato(Solanum tuberosum L.); new variety; growth period; yield; resistance; Hubei province
馬鈴薯(Solanum tuberosum L.)是湖北省重要的糧食、蔬菜、飼料和工業原料作物,常年種植面積近33萬hm2。從2009年開始,湖北省政府設立專項資金扶持發展馬鈴薯種植,使全省馬鈴薯生產得到突破性發展,取得了顯著成效[1]。但是湖北省馬鈴薯生產卻面臨著專用品種短缺,目前大面積種植的早熟品種仍然以費烏瑞它為主,品種單一的現狀已遠遠不能滿足現代馬鈴薯產業的發展需求,嚴重制約著馬鈴薯產業的發展[2,3]。為了尋求適合丘陵平原地區種植的高產、優質、抗逆性強的早熟品種,湖北省農業技術推廣總站于2009年冬季引進7個品種在湖北省東部、中部和西部的蘄春縣、潛江市、襄陽市的襄城區、十堰市的房縣、宜昌市的點軍區開展了冬種試驗,旨在考察引進品種的豐產性、適應性和抗逆性等綜合性狀,為馬鈴薯品種定向提供科學依據。
