Abstract : the main characters and seed set of bc1 , bc2 , bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied. the appearance of a large number of self fertile plants in ms line was analyzed. the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed. it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields
文摘:研究了雜交稻花粉對母本不育系回交後代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現,分析了不育系中出現大量自交結實株的原因,討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響,指出「同質恢」對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。The miscellany appeared in strains of myrica, casuarina and alnus were also partly coincident with what normand et al. ( 1996 ) and li zhizhen ( 2002 ) obtained : the clusters devided by the isolates from the myrica and casuarinahave grest genetic diversities. besides the analysis of the strains, we also tried to extract the dna of frankia from the nodules directly and analyse them also with the method of pcr - rflp
這些結果與baker ( 1987 )通過交叉感染試驗將來自不同宿主的50株frankia菌株分成4個類群的結果部分一致,但也暗示其可能具有局限性;此外,分析楊梅和木麻黃菌株所得到的結論支持了normand等( 1996 )與華中農業大學碩十研究生學位論文李志真( 2002 )所得的結論,即木麻黃和楊梅的菌株比較混雜,兩者都不能成為獨立的類群。Serious cross reation existed between v. albo - atrum and mv2, mv3, mv4. the other pathogen isolates v31 and v32 also had cross reactions, but the reaction was not serious. because limited number of pathogen isolates were selected, it could not prove that the selected immunogen was widely presentative, more pathogens isolates should be tested to verify the acquired hybridomas cells
5株單抗雜交瘤細胞中沒有一株具有種或屬的特異性,其中mv2在棉花黃萎病菌若干菌系間的檢測表明其能夠區分不同的致病類型; mv1和mv4組合檢測的結果基本上能將棉花大麗輪枝菌鑒定到種;黑白輪枝菌與mv2 , mv3 , mv4的交叉反應比較強烈,其他菌株v3 , v32有個別的交叉反應,但不強烈The authors discovered four peculiar phenomena, i. e., the self seed - setting and its genetic stability of the autoteraploid rice, the early - generation stabilization in the cites between alloploid rices, the self embryogenesis of autoteraploid rice wider isolated conditions, and a high seed - setting percentage in some plants of autotetraploid rice after the treatment of ion beam, in the research of autotriploid and autotetraploid rices

利用與糖基合成有關的基因str - de作探針對這兩個菌株的總dna進行了southern雜交,從兩個菌株的總dna中均檢測到一段相同大小的陽性片斷,約6 . 4kd ( bamhi + bglii酶切) 。2 - e4 - a and 82 - 6 are hybridized during their log growing time, and the hybrid - hybridomas are cloned for 3 times and produce 6 hybrid - hybridoma cells. the chromatosome of hybrid - hybridoma 3 - hu and hybridoma 2 - e4 - a and s2 - b are counted, and the antibody of ascites fluid or culture supernatant of 3 - hn is prepared. the positive clones are detected by three methods at the same time : rbc agglutination for monospecific anti - human rbc type a antibody, indirect elisa for anti - p24 antibody, and rbc solid - phase adherence for bispecific antibody
選其中一株3 - h _ ( 11 )做雜交-雜交瘤細胞染色體計數,同時計數兩母株2 - e _ 4 - a和s _ 2 - b的染色體數:制備腹水型和上清型抗體,用三種方法同時檢測其中的雙特異性抗體、單特異性抗人紅細胞抗體和抗p24抗體,即紅細胞固相吸附法測雙特異中文摘要性抗體,紅細胞凝集試驗測單特異性抗人a型紅細胞抗體,間接elisa法測抗p24抗體;用腹水型抗體做耐熱性及耐凍融實驗。The results indicated that opposite maize had widespread heterosis like alternative maize ; yield advantage of opposite f1 ( alternative alternative ) was better than that of f1 ( opposite opposite ) and f1 ( alternative opposite or reverse ) ; general combining ability of yield characters was decreased by opposite characters transfer maize, but alternative maize with opposite genes has high general combining ability, so that on the opposite maize breeding, alternative inbred lines with different opposite genes can be parents for breeding hybrid lines ( alternative alternative ) and hybrid varieties with more seeds and high yield can be obtained
結果表明:對生玉米同互生玉米一樣具有普遍的雜種優勢,在產量性狀上f1對生株優勢互互組合大於對對組合和對互(互對)組合;對生性狀的轉育對產量性狀的一般配合力有降低效應,而含有對生基因的互生玉米具有較高的一般配合力效應,因此,在對生玉米育種中可以利用含有不同對生基因的互生自交系作親本來組配雜交組合(互互) ,從而獲得較高的制種產量和高產的對生雜交種。In order to select male nucleo - sterile new genotype, a tentative idea was put forward for the nucleo - male sterility to attach a tps ( thermo - photoperiod sensitivity ) and a selection strategy of combination of selection and identification, at the same time, the spring and summer sowing method were used to provide different environment conditions of appraising sterility and tps. the results indicated that ( 1 ) sterility could be appraised under the spring sowing environment and tps could be appraised under summer sowing environment. ( 2 ) under spring sowing environment, sterility could be selected, but not maintained. thereby, lines selected could only be selected as recorded selection method in the experiment. ( 3 ) and then, selection was carried out from spring sowing line selected into summer sowing in same line with tps to select plants. these plants through the intercrossing selection had been combined with sterility and tps. in this way, a new selection protocol for selection sterile line with tps was formed. it mainly involves the spring and summer sowing method, recorded selection method and the intercrossing selection method
為了選育新類型玉米雄性核不育系,提出了為玉米核不育性添加溫光敏感性的設想和選擇與鑒定相結合的策略,同時應用分期播種的方法為作物提供不同的生長和發育的環境條件,以鑒定玉米雄穗的育性變化和對不同環境條件溫光的反應.研究結果表明,春播環境下可鑒定和選擇玉米的不育性,夏播環境下可鑒定和選擇其溫光敏感性.針對玉米核不育性難以找到保持系的特性,結合兩種播期選擇兩種性狀.但春播環境下選擇的不育性群體難以通過選擇單株來保持其不育性,為記錄性群體選擇.通過從春播入選的雜合不育性優良株系群體轉移到其對應的夏播溫光敏感性入選的同一優良群體中進行優良單株選擇,能逐漸使不育性和溫光敏感性相結合而選育出純合溫光敏不育系.這種新的選擇程序主要包括應用分期播種法、記錄性選擇法和春夏兩季交叉式選擇法,使含有不育基因的可育株系逐步累積不育基因並增加了溫光敏感性而育成玉米溫光敏不育系It was found that there were changes to some extent in the main characters of the days from seeding to initial heading, plant height and seed setting rate when the seeds of the tested hybrid rice combinations and their parents were sowed at different time in hainan for the seed purity identification, and the changing extent was different between some hybrids and their parents, which would affect the accuracy of purity identification
摘要通過比較不同播種時期雜交水稻種子樣品在海南種植鑒定的農藝性狀表現,發現播始歷期、株高、結實率等主要性狀均表現出不同程度的變化,且部分組合與其親本的變化幅度不同,從而影響鑒定的準確性。In fact, dormancy is very complicated because of its complex traits : the first one is regulated and controlled by complex genetic characters ; the second one is influenced by environmental factors, such as light and temperature, during seed development on the mother plants, during seed storage, and during germination
然而實際中有些種子同時存在著這兩種休眠類型,首先休眠受復雜的遺傳特性的調控,其次休眠還受到環境因素的影響,如種子在母體植株上的發育、儲藏期間以及萌發時的光照和溫度等。The segregation ratio of wild type plants to mutant plants in the population degenerated from heterozygotes was 3 : 1, indicating that the mutant is controlled by a single recessive gene, and designated tentatively as tor
同時,雜合株系呈典型的3 : 1分離比例,表明該突變性狀由單隱性基因控制,並將該突變體暫時命名為tor 。According to the southern hybridization results, 43 bacillus strains were divided into several groups, 22 strains were chosen randomly from all these groups for sequencing of aii gene. it was found that the nucleotide acid sequence of aii genes showed 85. 4 % - 100 % homology and amino acid sequence of aii proteins showed 8 8. 1 % - 100 % ho mology
