Breeding crops for organic agriculture

Organic farming is characterized by closed production cycles with minimum external input including the prohibition of the usage of synthetic pesticides. Weed control is optimized by crop rotation, mechanical treatments and competitive varieties. Pest and insects are controlled with predators, parasitoids, symbionts and resistant varieties. The nutrition of plants is provided with animal or green [...]

Parental control and its implication on selection gain

The value of the parental control (c) depends on the recombination and the recurrent selection method. C is 0.5 if selected candidates are pollinated by selected and unselected genotypes. I.e. genotypes are selected at harvest. However, unselected genotypes contributed to the pollen cloud and thus also contributed to the following generation. Thus, desirable alleles are [...]
