Breeding and exploitation of prolific breeds in Czechoslovakia
In the years 1971—1979 many experiments were conducted in order to elucidate problems of meat production increase in sheep. Ewes of native breeds (Mutton Merino = M, Improved Wallachian = I) were mated to rams of prolific breeds (Finnsheep = F, Romanov = R), producing F1 crossbred females.

Retrospective analysis of spring barley cultivars developed by Omsk breeders (1936–2021)
Plant breeding is an endless conveyor belt: cultivars developed earlier are included in hybridization plans and become the sources for new ones.

Defining valid breeding goals for animal breeds
Abstract Background The objective of any valid breeding program is to increase the suitability of a breed for its future purposes. The approach most often followed in animal breeding for optimizing breeding goals assumes that the sole desire of the owners is profit maximization.

Stupidity, immorality and social regression - the protection of animal rights in Poland compared to other European Union countries [PDF]
The paper concerns the protection of animal rights in Poland, at the level of legal provisions and application of norms. The author puts forward a thesis according to which the development of animal protection in Poland is weak and retarded in relation ...

Physiological breeding crosses parents with different complex but complementary traits to achieve cumulative gene action for yield, while selecting progeny using remote sensing, possibly in combination with genomic selection. Physiological approaches have already demonstrated significant genetic gains in Australia and several developing countries of ...

IPR 107 – Dwarf arabic coffee cultivar with resistance to coffee leaf rust [PDF]
‘IPR 107’ was derived from a cross between ‘IAPAR 59’ and ‘Mundo Novo IAC 376-4’. ‘IPR 107’ is a dwarf medium sizeplant with medium precocity in ripening and with complete resistance to rust races in this time.

Resistance gradient of black pod disease in cocoa and selection by leaf disk assay [PDF]
To characterize the gradient of resistance to black pod disease experimentally, the leaf disk assay was applied to 217cocoa genotypes. The parameters time interval, number of leaves evaluated per genotype and distribution of experimental treatmentswere ...
