Most of the triazole fungicides are widely used against rusts, powdery mildews and scabs. But triazole fungicides were harmful to fish and other aquatic organisms. And the Environmental Protection Agency has classified TBZ as a "possible human carcinogen" because it caused significant toxicity and reproductive effects on laboratory mice.

In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein. Other 14 genes were similar with known genes in databases including expansin (OsEXP2), late embryogenesis-abundant gene , an SR-related protein essential for spliceosome assembly (SART1), autophagocytosis protein , bHLH protein, fruit-ripening protein similar to ASR, nickel-binding protein 2A, DNA-binding protein, pyruvate dehydrogenase kinase , stomatin-like protein, SR1 induced by sucrose starvation, vacuolar protein sorting protein (VSP33a), gibberellin action negative regulator and retroelement.

Aimed at the arising problems such as the cross-incompatibility and hybrid's sterility during distant hybridization of fruit trees, effects of different treatments on cross-compatibility of distant hybridization in stone fruits were studied based on the former studies, then physiological and biochemical changes during hybridization between plum and apricot were primarily discussed, and rescue and culture system of hybrids' embryos were also conducted, further the genetic variation and principle between the hybrids and their parents were analyzed and methods of identification of hybrids were established.

针对果树远缘杂交过程中存在的杂交不亲和性及杂种不育性等问题，在前人研究的基础上，研究了不同处理对核果类果树远缘杂交亲和性的效应，并探讨了李、杏属间杂交过程中发生的生理生化变化以及花粉与柱头的互作，建立了李、杏属间远缘杂种的胚培养技术体系，建立了杂种鉴定检测方法，并分析了杂种后代与其父母本之间的遗传变异及规律，最终将一批远缘杂交新种质定植于大田，同时对自然界存在的杏梅种质资源进行了RAPD分析。

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.

5对参试杏梅种质资源的RAPD分析表明，杏梅与其近缘种之间亲缘关系较近，多态性相对较少；聚类分析结果显示大部分的杏梅与中国李的遗传距离较近，与形态学上的描述基本一致，因此杏梅种质资源在自然界中产生时，其母本可能为李；同时S等位基因的扩增结果显示杏梅与李的扩增条数一致，都为一条，因此推断杏梅与李的进化趋同性可能较杏更近。
