近20年我国李新品种选育概况文献调查研究

Reference Investigation on Breeding Plum New Varieties of Our Country in Recent 20 Years

为开展沙子空心李新品种选育研究,通过检索和筛选获得了近20年我国选育的53个李新品种的主要期刊文献,并统计和分析其中的每个李品种的名称和类别、期刊名称、报道年份、选用育种方法、主要育种单位、品种审定单位、育种开始年份、新品种审定年份等信息。调查结果表明,李新品种选育研究报道多集中在《园艺学报》、《中国果树》和《果树学报》等期刊上;东北地区和华北地区李育种研究工作在全国占有主体地位;成熟期、抗寒性、品质和丰产性为李新品种主要选育目标;杂交育种和实生选种是李育种的主要方式,芽变育种也是李育种的一种重要手段。这对沙子空心李新品的种选育研究提供了参考。
