Book (stand-alone)Manual on Mutation Breeding 2018The 2nd edition of Manual on Mutation Breeding (MMB) was published in 1977. After nearly 40 years it is necessary to update Member States (MSs) with current knowledge in practical plant mutation breeding methods and to provide a comprehensive overview and guidelines for crop improvement using induced mutation and mutation breeding techniques. In 1977 there were 106 IAEA Member States, and as of March 2015 there are 164 MSs. The irradiation services for mutation induction in plant breeding has risen proportionally with the number of MSs. Therefore, the interest for mutation breeding has been increasing. There are now over 3222 mutant varieties released worldwide in over 200 crop species, as compared to 571 mutant varieties in 84 crop species in 1977. Plant mutation breeding continues to be an active area for crop improvement. Plant mutation breeding is under-going a renaissance with new methods and wide application to more crop species in which it can provide shortcuts in developing new mutant varieties. This is particularly relevant in safeguarding food security and is required to meet environmental challenges caused by climate change (resistance to pest and diseases and tolerance to abiotic stresses).

BookletBreeding strategies for sustainable genetic improvement of Caucasian and Carpathian Brown cattle breeds 2020
Also available in:
No results found.The aim of FAO project TCP/RER/3604 was to elaborate breeding goals and plans for breeding and breed development of Caucasian Brown Cattle in Armenia and Georgia and Carpathian Brown Cattle in Ukraine. As a first step, information was collected about the breeds themselves and the environments in which they are kept. Approximately 300 phenotypic pure cows and 20 pure bulls were selected in each country, and phenotypic information was recorded. The assessments were carried out under the guidance of Tamas Szobolevszki, with support from each country’s national consultants and service providers. Genetic material was collected, genotyped, and used for a study on the genetic background of the breeds by the International Atomic Energy Agency (IAEA) in Vienna (FAO/IAEA, 2019). At two workshops held with stakeholders involved in the breed development of Caucasian/Carpathian Brown Cattle, a concept of a breeding strategy was developed, taking circumstances for implementation into account. The overall goal of the strategy is to conserve Carpathian Brown Cattle and Caucasian Brown Cattle breeds by making use of the potential for improving the breeds genetically. As the population of the pure Caucasian Brown Cattle in Armenia and Georgia is about 70 000 and 160 000 cows, respectively, this document has developed a breeding program with the aim of increasing the genetic gain for Pure Caucasian Brown, according the breeding goal for the breed. For Carpathian Brown, whose population is estimated at fewer than 1 000, the aim is to develop an in situ conservation program. -
