文摘：在简要介绍杏的起源、分布及种质资源收集保存的基础上，着重对杏品种资源的分类、授粉生物学、孢粉学及分子生物学评价以及杏杂种后代遗传变异特点、育种目标及育种技术进行了综述，并提出了今后的研究方向。

METHODS: The 15 hybrid dogs were randomly divided into 2 groups. In the experimental group (n=9), a hole was drilled at the slope beneath the tibial plateau to reach the medullary cavity. The cavity was enlarged by an appropriate drill to confirm the size of the cavity. The absorbable polyamide intramedullary rods were inserted from the hole in tibial superior extremity, and the fracture was anatomically reduced with the rod passing through the fracture. Two locking nails, which were cylinder polyamide rods, were respectively located 2 cm from the cutting site, in the distal and proximal ends. Auxiliary plaster external fixation was performed for 4 weeks. In the control group (n=6), quincunx intramedullary nails of the same diameter with 4 pre-drilled holes were accordingly inserted into the cutting segment, and 2 screws were locked in the distal and proximal ends, respectively.

15只杂种犬随机分为2组，实验组(n=9)：在距离胫骨平台下斜坡处钻孔入髓腔，用合适钻头扩大髓腔，确认髓腔大小，从胫骨上端开孔插入聚酰胺钉，解剖复位骨折端并使该钉通过骨折处，在距离截骨处2 cm处的远近端分别锁上2枚锁钉，锁钉为圆柱形聚酰胺棒，辅助石膏外固定4周；对照组(n=6)：同样插入相应直径的、已预钻4孔的梅花形髓内钉截段，在骨折端的近端及远端分别锁2枚螺钉，辅助石膏外固定4周。

Genetic diversity among 46 rice clusters was studied using the AFLP molecular marker, and relationship between genetic distanceand hybrid performance in a diallel set of crosses between them was assessed.

利用AFLP分子标记对46个水稻品种进行遗传多样性分析，继而研究分子标记遗传距离与按照NC设计获得的195个杂交组合的产量及特殊配合力的相关性，探讨预测杂种优势的可能性。

Basing on our early stage research work about collection and description of sugarcane germplasm and the aided project of Yunnan Natural Science Fund (2001 C0015Q), the wild species Erianthus fulvus, which has good characters, cold-resistant, drought-resistant, higher Brix and less chromosome number, was utilized for the first time through intergeneric hybridization with sugarcane cultivar. Its F_1 hybrids were appraised with some new techniques and methods for germplasm enhancement.

本研究在课题组考察采集和保育鉴定甘蔗野生种质资源的前期工作基础上，依托云南省自然科学基金资助项目(2001C0015Q)，首次利用具有特异优良性状(抗旱、耐寒、锤度高、染色体数目少)的蔗茅野生种与甘蔗栽培种或品种进行属间远缘杂交，扩大甘蔗遗传多样性；采用新技术、新方法对蔗茅杂种F_1代材料进行早期鉴定评价研究，筛选具有育种价值的新种质，为进一步选育生态适应性广、抗逆性强、丰产高糖的甘蔗新品种奠定物质基础。

Gametic selection was assessed with a doubled haploid population including 1 35 lines derived from anther culture of a typical indica and /japonica cross, ZYQ 8/JX 1 7, by investigating the segregation and recombination of morphological characters, isozymes and RFLP markers.

对典型的灿与粳稻杂种，窄叶青8号／京系17F1花药进行培养获得的132个双单倍体的形态特性、同工酶与RFLP标记的分离与重组进行了考察分析，研究是否存在配子选择问题。

The choice characters set up by regression and path analysises did not only provide basis ofchoice of charater for hydrid parent plant and hydrid progeny of rice but also opened a brightfuture for the application of computers in high-yield breeding.

回归和通径所确定的选择性状不仅可以作为对水稻杂交亲本及其杂种后代的性状选择依据，提高其选择效果，同时也为计算机在水稻高产育种中的应用开辟了广阔的前景。

The 1000-grain weight heterosis was mainly due to the grain fresh weight heterosis at 12 DPA and 22 DPA that the intervarietal hybrid had, and also due to its promotion of 2 kinds of hormone IAA and CTK 12 DPA, the IAA function extended to 22 DPA.

品种间杂种也具有一定的千粒重杂种优势，这与12天、22天籽粒的鲜重优势有关，籽粒发育早期（12天）2种促进型激素IAA和CTK促进籽粒生长，与其获得较大的鲜重优势有关，IAA的促进作用可延伸到22天。

To study the molecular mechanism of Larix somatic embryogenesis, a differentially expressed cDNA library of Larix somatic embryo in the period of maturation was constructed using suppression subtractive hybridization. The cDNA from the cultures at the stage of somatic embryo maturation of embryogenic cell line Y35 of L. leptolepis ×L. principis-rupprechtii was used as the tester and the cDNA from its subcultured callus was used as the driver. Eight hundreds randomly selected positive clones were sequenced, and 468 UniGenes were obtained finally.
