株两优312的高产制种技术 总被引：1，自引：0，他引：1
株两优312是德农正成种业长沙水稻研究所用湖南株洲市农科所选育的低温敏广亲和两用核不育系株1S／和自选的两系早稻父本R312配组选育而成的籼型两系杂交早稻中熟组合。2006～2007年参加国家长江中下游早稻区试,2008年通过国家农作物品种审定委员会审定,2006年在国家区试中表现理想。为了该组合早日走进市场,为市场提供优良的合格种子,我们在湖南、广西进行了大面积制种,一般产量200kg／667m^2以上,经过认真分析制种技术与制种基地当地气候和栽培习惯,我们基本掌握了株两优312的亲本特征特性及该组合高产制种技术,现将该组合的高产制种技术现总结如下： 相似文献

两优0293系湖南杂交水稻研究中心以P88S作母本、0293作父本测交而培育的一个超高产组合。2005年通过湖南省审定,2006年通过国家审定(审定编号:国审稻2006045)。该组合在示范栽培中表现出高产、优质的特点。2005年我县承担了袁隆平院士下达的100亩栽培示范任务,测产验收结果,平均亩产816.0 kg。2006年我县将两优0293扩种到1 000亩,经县农业局组织农业专家临田现场测产验收,平均亩产822.1 kg。两优0293栽培之所以获得高产,从技术上总结,我认为主要是根据其生育特性采取相应的技术措施,充分发挥了其增产优势的结果。 相似文献

香蕉是热带亚热带发展中国家重要的粮食作物和碳水化合物来源。但近年来,香蕉生产受到严重的病虫危害。大多数香蕉栽培品种是三倍体,生长周期长,而且不孕。由于没有种子,给繁殖和育种带来一定的困难。遗传转化技术的发展为香蕉品种的改良提供了一种有效的手段。香蕉的遗传转化方法有电激法、基因枪法、农杆菌介导法等。农杆菌介导法的应用是香蕉品种改良的一个重大突破。香蕉遗传转化的外植体也发展到多种,有原生质体,胚性细胞悬浮系,分生组织,以及横切薄片等。近几年,随着分子生物学的发展,出现了转化效率更高,重复性更好的香蕉遗传转化技术。如农杆菌和基因枪结合法,离心辅助农杆菌介导法、真空渗透技术等。这些新技术新方法的出现,必将推动香蕉产业高速发展。 相似文献

Automobile comfort dynamic simulation is necessary when we predict and evaluate the comfort of a automobile or optimize performance of automobile. The nine DOF vibration model of automobile is established , which acts root mean square value of body in multiple work conditions as comfort evaluation indices. Based on the comfort simulation, the Hongyan 1160 is predicted in the way of comfort. The programmes can be used in many different automobiles . The computational result indicates that the model can simulate vibration of automobile truly. It is significant to research automobile comfort evaluation to optimize performance of automobile and comfort simulation .The computational program can be applied to optimize or simulate which has some reference value. 相似文献

Applicability of molecular markers in the context of protection of new varieties of cucumber 总被引：2，自引：0，他引：2

The growing number of candidate varieties presented every year at each national Plant Variety Protection Office and their decreasing genetic variability forces strategies to be adopted that will reduce costs without losing rigour when deciding about the acceptance or rejection of a candidate variety. Molecular markers have been envisaged as a reliable tool to establish differences, but can molecular markers be used for assessing distinctness? A comparison between a molecular and a morphological characterization of 41 seed samples belonging to 36 cucumber varieties and including several external controls has been carried out to investigate the applicability of molecular markers in the context of distinctness, uniformity and stability (DUS) tests and the protection of new varieties. Both types of character indicate the same relationships among main groups, Dutch and Beth‐Alpha types, and Gerking and Slice types, the correlation between distance matrices being only 0.6489. Varieties considered uniform for morphological traits proved not to be so for molecular markers. Therefore, molecular characterization is not offering the same estimates of uniformity and relatedness between varieties as does morphological characterization. External controls were used to establish distinction limits with morphological and molecular dendrograms to focus on those varieties, which were suspiciously similar. The results with cucumber show that molecular identity could be used to assess any lack of distinctness and so corroborate the morphological assessment of candidate varieties. The morphological trait ‘type’ provides distinct characterization of varieties and the molecular characterization of candidate varieties could be used to design better field experiments to assess distinction within each group of morphological cucumber type. 相似文献
