According to the number and behavior of B genomechromosomes, all hybrid plants were classified into three types. All somatic cells of TypesⅠplants contained 16 B genome chromosomes which formed 8Ⅱat diakinesis and shown8:8 segregation at anaphase; TypesⅡcontained 14 B genome chromosomes whichformed 6Ⅱ+2Ⅰat diakinesis and showed 6:8 or 7:7 segregation at anaphase. TypesⅢcontained above two chromosomes number and behavior.

同时根据B基因组DNA为探针的GISH结果，以细胞中B基因组染色体的数目及减数分裂时的配对及分离的方式，将所有杂种植株分为三大类：Ⅰ类具有16条B基因组染色体，以8Ⅱ的方式配对，以8：8分离，共32株；Ⅱ类具有14条B基因组染色体，以6Ⅱ+2Ⅰ方式配对，以7：7或者6：8的方式分离，共4株：Ⅲ类植株包含有上述两种细胞类型类型，共1株。

Molecular systematics on germplasm resources of oak silkworm, Antheraea pernyi , including genetic diversity, cultivar taxonomy and microevolution within species, were investigated using Random Ampified Polymorphic DNA, mtDNA sequence analysis and population genetic analysis.

So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other.

在砧木选择研究进展上，中国调查出和引进了一些优良的柑橘砧木种质资源，通过体细胞融合选育出一些可作为柑橘砧木的柑橘体细胞杂种资源；在柑橘砧木资源的遗传稳定性、嫁接亲和性和矮化性等早期鉴定上，探索出一些有待完善的鉴定方法；在砧木选择上，选出一些具有某些优点的砧木，但尚不能冲击枳砧的主导地位，并且选择研究方法有必要把现行单纯的砧木比较改为与砧木种类、栽培技术或环境条件相结合进行比较。

These genes are related to many plant functions, indicating that the heterosis was related with many metabolization pathways.1.2 The quantity of discrepant genes showed that the genetic discrepancy was notalways the same with the discrepancy of expressed genes, indicating that small-scale genetic discrepancy maybe result in large-scale genes discrepantly expression; in other way, some genetic discrepancies might not embodied on the discrepant genes in the experiment.1.3 Nine and eight discrepant genes were found respectively in the superior bulkand minor bulk in the dominant level.

1.2 各张芯片差异表达基因数量表明遗传差异与表达谱差异不尽一致，可能较小的遗传差异可以造成表达谱的巨大改变，而有些遗传变异可能没有在表达谱上表现出来。 1.3 从优势集团和负优势集团中分别找到9个和8个具显性表达水平的差异表达基因，研究表明显性表达水平的差异表达基因的聚合与杂种优势的表现没有相关性。

The results showed that karyotypic type of Ya01-21was 2n=104＝100m+4sm（4SAT）, Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132＝130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.

研究结果表明，崖城01－21的体细胞染色体核型公式为2n＝104＝100m+4sm（4SAT），最长与最短染色体的长度比为4.25，平均臂比1.35，染色体属2C型，分子鉴定结合细胞学研究认为其为斑茅的真实后代，其染色体遗传为n+n；崖城01－36经ITS签定为真实杂种，其体细胞染色体核型公式为2n＝132＝130m+2sm，最长与最短染色体的长度比为3.94，平均臂比1.27，染色体属2B型，结合其性状的进展，推断亲本向其传递染色体可能以2n+n的方式进行。

Fromthese facts,It could be deduced that 8 to 14 pairs of chromosomes possessed a certaindegree of hetorology,which was directly groved to be hybrid origin of P.tomentosaaccording to the good chromosome homology and fertility of P.bolleana and thehybrids of P.tomentosa×P.bolleana,it could be further deduced that the original parentsof P.tomentosa involved probably P.bolleana or P.alba.

从终变期、中期I的染色体构型看，有数目不等的联会程度较差的单价体和棒状二价体出现，在后期I，甚至末期I亦可见到含落后染色体分裂相的细胞，由此推断可能有8~14对染色体表现出一定程度的异源性，鉴于新疆杨以及毛白杨与新疆杨杂交产生的杂种毛新杨的染色体同源性较强、育性较好等现象，进一步推断毛白杨起源亲本可能包括新疆杨或银白杨。

Results of grafting trial shows: the budding survival rate on hybrid UCB-I was higher commonly than that on the Pistacia atlantica Desf; On two rootstocks, one-year-old branch performed better than twoyear-old stem; In mid August, the highest budding survival rate was attained with two rootstocks; After treatment with 50、100ppm IBA and 50ppm 6-BA, the budding survival rate on hybrid UCB-I was decreased, but the budding survival rate on Pistacia atlantica was increased evidently, particularly it has been increased 22. 8％ by treatment of 100ppm IBA.

阿月浑子嫁接试验结果表明：在杂种UCB-I上的芽接成活率普遍高于在大西洋黄连木上的芽接成活率；两种砧木一年生枝上的芽接成活率均高于二年生主干上的芽接成活率；8月中旬在两种砧木上的芽接成活率均最高；用50、100ppm IBA和50ppm 6-BA处理接芽后，均可显著提高大西洋黄连木上的芽接成活率，尤其100ppm IBA处理可提高其嫁接成活率22.8％，但上述处理都降低了在UCB-I上的芽接成活率。

The CORNELL/COPERSUCAR/USPA project for the application of RELP technology in sugarcane encompasses three objectives: aEstablishing measures of genetic distance among and within species of the Saccharum complex and hybrids. bDevelopment of a genetic linkage map applicable to the saccharum genera.

CORNELL/COPERSUCAR/USPA 合作的多倍体的核酸内切酶内切限制断段变化技术应用于甘蔗，包括三个目的：a建立甘蔗属的合成物和杂种种内和种间的基因距离的测定。b发展应用于甘蔗属的基因链锁图。c努力建立分子标记和农学特性之间的链锁。

The other two groups are longan and'Longli, a special germplasm', which is a natural hybrid of litchi and longan. The results from RAPD analysis also showed that longan might be the maternal parent and the extremely early maturing litchi types be the paternal parent since'Longli'is closer to longan in the taxnomy. This information would be useful in the distant crossing breeding to fruit of Sapindaceae family.

根据RAPD分析揭示的多态性水平和聚类分析结果及马贵荔×焦核三月红的F〓杂种群体表现出的广泛分离和父本特有RAPD位点分离方式的偏态性，本研究对荔枝的分类学提出新见解，认为广东的三月红、云南的褐毛荔等极早熟荔枝类型（在广州于5月20目前成熟）在分类上可自成一类，其地位应提高到&变种&一级。

Rivers of blood! A long time ago the lands surrounding Algalord lived through the worst moment in their history: the deeply despised "times of darkness"... times of bloody battles between the forces of the "Holy alliance" and the hellish army of the bastard known as the "Black King".
