摘要
1965～1995年间，首次选用了我国南方核桃良种云南薄壳核桃与我国北方新疆早实丰产优株核桃两大核桃种群进行种间杂交育种研究．按照杂交育种程序，经三十多年的试验研究，培育出了7914，7926、8034、8064、85227等5个杂交新品系核桃．所培育出的新品系核桃具有早实、丰产、优质、树体矮化及适应性广等特点，达到了预期的育种目标．
Interspecific crossing was carried out from 1965 to 1995 with fine Northernwalnut cultivars (Juglans regia) and fine Southern walnut cultivars (J. sigillata), with aview to altering the late--bearing charcteristic of the latter. As a result, five crossed strainswere developed, namely, 7914, 7926, 8034, 8064, and 85227, and they have all proved to beprecocious, prolific and highly adaptable dwarf trees that bear quality nuts, thus successfullymeeting the breeding objectives.
