|
摘要
青海核桃栽培历史悠久,黄河流域广泛分布着品质优良的农家地方良种,有些可直接在生产中扩繁,部分是核桃育种珍贵资源。结合国家林业局"青海省核桃遗传资源调查与编目"项目,从2015年开始,对我省有核桃自然分布的3州(市)6县1区24个乡镇开展了为期三年的综合调查,2015年先后共标定核桃树92株,经过比对、定名,共标定青海省地方品种26种,57株,引进品种14种,27株。
Qinghai has a long history of walnut cultivation,the Yellow River Basin is widely distributed in the quality of the local farmers varieties,and some can be directly in the production of propagation,part of walnut breeding valuable resources. Based on the project of "Investigation and Cataloging of Walnut Genetic Resources of Qinghai Province"by the State Forestry Administration,from the year of 2015,we carried out a three-year comprehensive survey on the natural distribution of walnut in Qinghai Province,including 3 counties( citys) in 2015,a total of 92 walnut trees were calibrated,and 26 species and 57 strains of local varieties in Qinghai Province were identified,and 14 varieties and 27 strains were introduced.
