摘　　要：为了提高陇南地区核桃资源优势以及培育与研发优良单株,通过连续4年对定位的核桃优树跟踪观测,筛选出丰产、稳产、抗逆性强的核桃优树12株,这些均属于薄壳核桃,3号、4号优树综合品质最优;6号优树为紫仁核桃,核仁风味浓香;8号优树果小壳极薄,仅0.81 mm;9号优树具有穗状核桃的特点;1号优树产量相对最低,但抗晚霜能力最强。此次调查筛选结果可为陇南地区核桃优良品种开发以及核桃育种提供参考。In order to improve the resource advantage of walnut(Juglans regia L)and cultivation and development of superior individual plants in Longnan area,through the follow-up observation of the positioned walnut superior trees for 4 consecutive years,12 walnut superior trees with high yield,stable yield and strong resistance were screened,which belonged to paper shell walnut.Among them,No.3 and No.4 superior trees had the best comprehensive quality;No.6 superior tree was purple walnut with strong flavor of kernels;Nut of No.8 superior tree was small,but the shell was extremely thin,only was 0.81 mm think;No.9 superior tree had the characteristics of spike walnut;The yield of No.1 superior tree was the lowest,but its resistance to late frost is the strongest.The results provide reference for the development of walnut varieties and walnut breeding in Longnan area.
