譜系育種 的英文怎麼說
中文拼音 [pǔxìyùzhǒng]
譜系育種
英文
pedigree breeding-
Only homothallic cbs g possessed a single independent lineage. both a. mellea and a. tabescens appeared in two groups. the two clusters of a. mellea correlated to the geographical origin of the isolates, one is the north american lineage and another is the european lineage
用11個種43個圖譜的數據建立了聚類樹圖，可以清楚地見到9個類群，只有cbsg擁有一個單獨的發育系，蜜環菌狹義種和假蜜環菌都存在兩個不同的發育系，蜜環菌狹義種的兩個發育系與地理起源有關，一個是北美菌株發育系，另一個是歐洲菌株發育系。2. the data from zymogram ( est bands and their rf ) are transferred into bimorphic characteristic data. a data matrix is established based on the data and calculated by phylogenetic analysis software package winclada 1. 00. 04, and then phylogenetic trees of intraspecies and interspecies are mapped
2 、將所獲得的盲蝽科4亞科11屬23種盲蝽雄雌個體的酶譜數據（酶帶和相對遷移率rf ）轉化為二態特徵數據建立矩陣，應用系統發育分析軟體包winclada1 . 00 . 04對數據矩陣進行分析運算，並分別獲得各個亞科內和亞科間的系統發育樹。The karyotypes often of them were analysed. the rapd fingerprints and systematics of thirty wild species including the fourteen wild species mentioned and two cultivars in the family were studied. these were intended to provide theoretical reference at the cytological and molecular lever for species identification, systematics study and breeding work of these plants
本文對海南境內的14個野生種菊科植物進行了染色體計數，並對其中的10個種進行了核型分析，同時對包括上述14個種在內的30個野生種菊科植物和2個栽培種菊科植物進行了rapd指紋圖譜與系統學研究，旨在為這些植物的物種鑒定、系統學研究和育種工作提供細胞學水平、分子水平的理論依據。Thermocycled pcr samples were resolved electrophoretically on 1. 5 % agarose gels and taken photos using a polaroid camera. the statistical results were analyzed by the spss software, and the cluster figures were obtained. conclusions could be drawn from the study as following : 1 ) the molecular systematics of 57 species of crickets, which belong to 26 genera 7 family in grylloidea, had been studied by the approach of rapd
本項研究在依據外部形態分類鑒定及前人工作的基礎上，採用rapd技術，通過對蟋蟀總科7科26屬57種蟋蟀基因組dna的rapd圖譜的比較研究，在分子水平上探討這些類群的分類地位和親緣關系，為豐富蟋蟀總科的分子系統學研究，並為進一步完善蟋蟀總科的分類系統，揭示其系統發育及演化提供分子水平的依據。Then the genetic distance and shannon information index among these 13 strains were obtained by using the software popgen2 on the basis of pcr - rflp patterns. the phylogenetic tree was constructed by using the upgma algorithm method ( mega2 software package ). the shannon information index indicated that there was a higher genetic diversity among the frankia strains and some strains had a big genetic distance with others
根據酶切圖譜，通過popgen2軟體計算各供試菌株之間的遺傳距離；用shannon信息指數計算種群遺傳多樣性；利用upgma法（ mega2軟體）對所獲得的遺傳距離矩陣進行聚類分析，得到13株供試frankia菌株間系統發育的聚類分析樹狀圖譜。Abstract : the application of random amplified polymorphism dna ( rapd ) to aspects of cultivar identification and classification, pedigree analysis, genetic map construction, hybrid identification, mutant detection, gene localization in genetics and breeding of horticultural plants was introduced
文摘:介紹了rapd技術在園藝植物品種鑒定和分類、系譜分析、構建遺傳圖譜、雜種鑒定、突變體檢測、基因定位等遺傳育種研究領域的應用。Recently, the sugar beet varieties bred in china are limited in hereditary basis and genetic variation genealogy
