An overview of the epidemiology and epizootology of brucellosis in selected countries of Central and Southeast Europe

The objective of this paper is to give an overview of the epidemiologic and epizootic status of brucellosis in selected countries of Central and Southeast Europe (Balkan region). Based on dimension of the disease problem, there is a need to establish collaboration in the eradication and prevention of brucellosis between all countries in the region. Although there were no readily accessible data concerning epidemiology and epizootology of brucellosis in these countries, the limited official and published data were analyzed.

The incidence of brucellosis caused by Brucella melitensis in sheep, goats and humans is a very significant problem in Macedonia and Greece. In Greece, cattle are also affected either by B. melitensis or B. abortus. The disease is an endemic problem in some regions of Yugoslavia and includes B. suis biovar 2 in pigs and in Croatia, B. melitensis in sheep, goats and human is found occasionally. No problem appears to exist with brucellosis in Bulgaria.

Financial well-supported brucellosis control programs of the European Union that will include all countries, regardless of the magnitude of brucellosis incidence, are needed for eradication and control of brucellosis.     

利用南斯拉夫玉米自交系改良478的效果初报

本研究通过对14个（478×外引系）后代选系与国内属于不同优势类群的8个骨干自交系杂交组配的56个测交组合的配合力和杂种优势研究结果表明：利用南斯拉夫自交系9804、9805、9806改良478是可行和有效的,在14个（478×外引系）优良后代选系中,有3个选系的GCA为显著和极显著正值,具有较高的直接组配利用价值。在56个测交种中,有13个单株产量显著或极显著高于CK 3.85%~33.28%。     

Variation in Yugoslavian hot pepper (Capsicum annuum L.) accessions

A total of 67 hot pepper accessions were evaluated based on 35 morphological and physiological characters. Differences were observed in a number of characters. The accessions were grouped into six clusters, mainly based on fruit weight, 1000 seed weight, and fruit number per plant. This revised version was published online in July 2006 with corrections to the Cover Date.     

中国和南斯拉夫异地育种对南斯拉夫玉米群体改良的效果

1985-1997年对南斯拉夫玉米群体SYN1/9C0进行半同胞轮回选择。1998年在唐山对C1-C6和在贝尔格莱德对C4-C6等共计10个轮回群体与4个标准自交系进行半双列杂交研究。两年的试验结果表明，群体产量和杂交组合产量以及杂种优势、配合力和田间部分性状一般配合力均存在显著差异，南斯拉夫和唐山两地改良效果极具互补性。实验还表明，中国、南斯拉夫异地育种的提高南斯拉夫玉米群体自身产量、杂交组合产量的同时，能更为有效地提升群体杂种优势，使产量特殊配合力、一般配合力同时提高。
