五个短需冷量桃品种在北京温室的表现

The Performance of Five Low Chilling Peach Varieties in Greenhouse of Beijing

对新引的几个短需冷量桃品种在北京温室进行观测,并对它们的物候期、生长结果习性、果实性状等进行调查分析。结果表明:除了FlordaGrande,其他4个品种都可以在温室中直接利用。其中,Desertred和Sunsplash特点突出,也是选育温室专用桃品种的优异育种资源。De-sertred生长势较弱,果实经济性状良好;Sunsplash果实风味非常浓郁,可溶性固形物为12.5%～14%,达到了露地桃栽培的水平。FlordaGrande需冷量极短,仅仅75h,早花性好,是一个特异育种材料。
