The study suggest:(1) The observation of satellites in root tip and multiplex PCR makers could accurately identify the homozygous and the heterozygosis of 1BL/1RS translocation.(2) Through the restoring degree we could confirm the success of the transfer. The combination of the restoring degree and the agronomy property could increase the efficiency of practical application.(3) This study proposed the transformation from the physiological male sterile to the genetic male sterile, and then establish a method of utilize the strong superiority crosses.

其中复合引物PCR更适合于回交后代中大量目标种子的筛选；(2)恢复基因转育后代定株与不育系测交，依据测交恢复度可准确确定恢复基因在回交后代的延续，恢复基因定株定向转育与性状选择结合可大大提高转育后代的实际应用效果；(3)本研究提出的粘类小麦雄性不育恢复基因Rfv1定向转育体系，可有效地实现小麦由化控强优势组合向三系强优势组合的定向转化，即生理型不育途径向遗传型不育途径的定向转化，进而建拓一套杂交小麦强优势组合多途径利用新体系。

To disease resistance, SP3 (from H1) had stronger ability to resist leaf mold. 4.The characters obtained by space mutation were easier to be stable. The results showed that, the differences of the flowering dates of 1st inflorescence, the positions of 1st inflorescence, number of leaves between 1st and 2nd inflorescences in the colony were decreased with the development of generations. Most of these heritable characters could be stable in SP3 and a few could be stable in SP4, 2~3 generations earlier than that of traditional breeding (The characters were stable in 6 generations.).

试验结果表明，植株的第一花序开花期、植株的第一花序节位、第一至第二花序间隔叶数及产量的株间变异（变幅、标准差和变异系数），随着世代的递增而降低，大部分株系的变异性状从SP3后就稳定遗传，少数株系的变异性状从SP4后才稳定遗传，比一般常规育种的6个世代开始稳定，可提早2～3个世代，经地面定向选择能较快选出综合性状优良的目标株系。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.

菌株的亚克隆基因组片段中，分离出phaA、phaB和phaC三个基因片段，定向克隆至原核表达载体pBV220，通过对其生物活性与功能分析，确证了基因phaA、phaB和phaC的生物学功能；为了通过植物生物反应器对这三个基因进一步研究利用，本实验利用这三个基因构建了两组可用于不同植物生产PHA的真核表达载体，并对紫叶酢浆草进行PHA基因遗传转化的初步研究，获得主要结果如下：利用克隆的phaA、phaB、phaC三个基因分别构建了可用于转化紫叶酢浆草表达载体pBI121-A、pBI121-B、uBquiting-C；可用于玉米转化的种子特异性表达载体p7S-A、pBI121-S-B、uBquiting-C。

The fact that the pink plants were predominant among the population of RP1 cross progeny hints that the pink had the strong descendiblity, Whereas another fact that the plants with the color of another parent were predominant among the population of R01 cross progeny indicates that the nacarat/saffron plant had the low descendiblity. The above results suggest that it is better to choose the pink plants with the target color flower of breeding as a parents when arranging the cross combination. Many novel flowers with singular value of view and admire can be bred by the different cross combination since the wide segregation chromatogram is not confined to the parents'.

以RPl及R01作母本或父本，分别与不同花色杂交，F1代发生了明显的花色分离，RP1的杂交后代均以粉色占优势，表明粉色的遗传力较强，R01的杂交后代均以其它亲本占优势，表明桔黄/桔红的遗传力较弱，因此在选配组合时，最好选择具有育种目标的粉色个体作为亲本；另外由于分离谱较广，且分离的色谱范围并不完全限于双亲之间，可根据不同的杂交配组，培育出具极高观赏价值的稀有花色。

The splicing／decomposible encoding scheme proposed by Xu et al is applied to the construction of dynamic selection and mutation operators that were built respectively on the levels of genotype and phonotype of population.
