为开发利用红花串核桃这一优良种质资源，对形态学特征和主要生物学特性等品种特性进行了观测，制定了育种策略并探讨了品种选育技术。红花串核桃属于早实晚熟丰产耐晚霜品种，为薄麻壳泡核桃，具有二次开花结实特性；第一次果的生产利用价值和商品性能高，8年生单株产坚果15kg以上，坚果椭圆形、整齐端正、缝合线高，种仁浅黄色，取仁易、取整仁，平均单果重14．28g，种壳厚1．3mm，出仁率54％；第2次果是核桃遗传育种的新型试材，目前的生产利用价值和商品性能较低。

In order to develop and utilize the excellent germplasm resources of Red Flower String Wal- nut, its variety characteristics of the morphological and biological characteristics are observed, meanwhile, breeding technologies and strategies are proposed. Red Flower String Walnut is a thin shelled walnut which belongs to a variety of early-fruit, late-mature, high-yield and frost-resistance, and it has the characteristic of secondary flowering and fruiting. The first fruit production value and commodity is very high, and 8-year-old individual tree can produce nuts more than 15kg. Its nuts were oval and neatly upright ,and its shell seal were high. The seed is light yellow, and it＇ s easy to be taken, even wholly. The average weight of single nut is 14.28g, with 1.3ram of shell thickness and 54% of the kernel rate. Second fruit walnut is a new-type test material of genetics and breeding, but currently its production value and product performance are relatively low.
