摘　　要：为了促进秋冬种区马铃薯产业的健康稳定可持续发展,根据马铃薯冬作区的生态条件及耕作栽培制度,构建马铃薯的生态育种技术并应用该技术选育新品种。通过对较耐寒抗病早中熟材料的选择利用、杂交;低温驯化实生种、实生苗;冬种环境条件下进行实生薯家系、株系、品系鉴定;不同生态条件下适应性和丰产性鉴定、区域试验、生产示范以及抗性鉴定。构建了冬种马铃薯的生态育种技术并应用该技术选育出聚合了耐寒、抗晚疫病、早熟、高产等多个特性而且通过了广西农作物品种审定委员会审定的桂农薯1号和桂农薯4号马铃薯新品种。针对马铃薯冬作区特定的气候生态条件与耕作栽培制度,构建与之相适应的生态育种技术,能够培育出适合该区域种植的聚合耐寒、抗晚疫病、早熟、高产等多个特性的马铃薯新品种。In order to promote the healthy and stable development of industry of potato planting area in autumn and winter,according to the ecological conditions and the cultivation system of the area where potato cultivated in winter,the potato ecological breeding technology(PEBT)was created and using this technology to breed varieties was practiced.The cold and disease resistance germplasm with early and middle maturity were selected,utilized,hybrided.The seeds and seedlings were domesticated in low temperature.The family and strain of potato tuber from seedling and potato lines planted in winter were identified.These potato lines were tested and demonstrated production in different region.The regional adaptability trial,the high yield performance,and the resistance of them were evaluated under different ecological conditions in winter.The PEBT was constructed,and the new potato varieties of Guinongshu1and Guinongshu4with cold tolerance,late blight resistance,early maturing,highyield were breeded by using it.Guinongshu1and Guinongshu4were approved for registration by the Guangxi Committee for Crop Variety Registration.The PEBT was established by aiming at the specific climatic and ecological conditions and cultivating cultivation system in the area of potato planted in winter.The new potato varieties with many characteristics such as cold resistance,late blight resistance,early maturing and high yield suitable for winter planting area could be breeded by using the PEBT.
