摘要：基于远缘杂交技术路线,以引进的俄罗斯大果沙棘丘依斯克和蒙古大果沙棘乌兰格木两个栽培种为母本,以中国沙棘为父本,开展了杂交选育研究,在子代林为7年生盛果期时,共择出13个优良单株,其中从中国沙棘与丘依斯克的杂交子代中选出10个优良单株,从中国沙棘与乌兰格木的杂交子代中选出3个单株。13个优良杂种单株树高、地径、冠幅均显著高于母本乌兰格木和丘依斯克,但大多低于父本中国沙棘。杂种2年生枝棘刺数为2～4个,界于父母本之间,与中国沙棘雌株相比,棘刺数减少70%。优良杂种单株果实百果质量为22.17～48.92g,除个别出现超亲现象外,大多明显小于母本,但较中国沙棘提高10.57%～143.99%。13个杂种单株产量与两个母本较为接近,但明显高于父本中国沙棘,是中国沙棘的3倍以上。综合评价结果表明,所选优良杂种单株生态适应性、经济价值分别明显高于母本引进品种、父本中国沙棘,生态经济价值十分优良。
In order to improve seabuckthorn for both fruit production and soil erosion contro1,Chinese Seabuckthorn（H.rhamnoides subsp.Sinensis） as male parent was crossed with Russian and Mongolian Seabuckthorn（H.rhamnoides subsp.Mongolica） as female parent.The Russian and Mongolian cultivars have large fruits and few or nearly no thorn,and were originated from the selection made in the Altai region.Crossbreeding trial was started in 1994.Thirteen 7 years old hybrid individual trees were selected of which ten individuals were from the crosses of Chinese（♂） to Russian（♀） culfivars and three from crosses of Chinese（♂）to Mongolian（♀） cultivars.Experimental results indicated that the selected 13 hybrids were significantly larger than the female parents in height,ground diameter and crown width,but most smaller than the male parents.The number of thorns in 2-year-old branches of the hybrids was 2-4,falling between the numbers of thorns in male and female parents,but a 70% reduction compared to Chinese cultivars.The 100-berry-weight of hybrids was 22.17-48.92g,except for one individual which showed exceeding parent fact,most significantly smaller than that of the female parents,but 10.57%-143.99% larger than that of the Chinese cultivars.The fruits yields of thirteen hybrids were quitely near to the two female parents,but obviously higher than Chinese Seabuckthorn.Comprehensive evaluation results showed that the ecological adaptability and economic value of the selected thirteen hybrid individual trees were obviously higher than female parent and male parent respectively,and the ecological and economic values of the selected hybrids were excellent.
